How to lubricate the gearbox of an electric jigsaw. Jigsaw. Service and useful tips. Jigsaw Diold: a budget option for the household

Repairing a jigsaw with your own hands is quite possible, but it is worth noting: there are troubles that cannot be eliminated with a conventional tool. For example, a breakdown of an electric motor requires qualified intervention, since only a specialist can fix such a malfunction.

Let's consider what happens to a jigsaw during its operation. Now it is difficult to find a model that does not have the function of feeding the blade forward to reduce the load on the owner’s hand. The presence of such an operating mechanism causes increased wear of individual structural elements. We are talking about the guide roller, as well as the rod bushings. Other typical situations include:

. It occurs when the sawyer is overzealous and puts a lot of pressure on the horizontal feed. In inexpensive models, the file can damage the fragile holder. Another common breakdown is the failure of the rod, as a result of which the jigsaw ceases to fulfill its purpose and the saw does not move.

Lack of service. Causes increased bearing wear, abrasion of the cam block in some models, and deterioration of gears.

Failure of electrical components systems. We are talking about a start button, which is often associated with the engine speed controller.

Long operating time. Affects the condition of the current-collecting surfaces of the engine and wears out the brushes. Repair consists of replacing the relevant parts.

Periodic maintenance - cleaning the insides from small sawdust, replacing brushes and lubricant - will extend the life of the electric jigsaw and prevent its failure.

Blade holder faults

Many modern jigsaws are equipped with bells and whistles, which are their weak points. For example, some models often require repair of the saw blade mount due to the presence of such functions as:

• Quick clamp, which does everything for the owner of the tool: just move the lever, place the blade and work. Over time, the structure becomes loose and fastening parts become unusable. Unfortunately, most of these clamps cannot be repaired; they must be completely replaced.
• Lightweight screw mount- a real problem for owners of cheap and mid-priced instruments. The rod attachment, made of weak alloys, has low strength, breaks, and the bolts break the seats. Repair consists only in the handicraft production of the appropriate product from durable steel, since each line of cheap tools often has its own saw blade holder configuration.

If the jigsaw has a classic screw fastening of the file, then repairing it will not be difficult. This is a durable and time-tested design; you can use bolts for a Phillips screwdriver or a wrench. The clamping blocks are standard; finding a replacement for an extremely worn part is not difficult. There is a problem with thread wear, but in this case you can cut a new one.

Repair steps

It is easy to disassemble the tool. The case is divided into two halves, allowing access to all parts of the mechanics. The first step is to remove contaminants and replace the lubricant, after which you can begin repairs.

Replacing stem bushings

Let us note right away that there are no spare parts in stores. You can find the corresponding part by purchasing a broken tool at a flea market. Parts from other devices and mechanisms are often suitable. For example, jigsaws with a round stem exit are the easiest to repair. A round bushing is selected; if necessary, the internal diameter is increased by stuffing it onto a cone. This repair allows you to eliminate runout and play of the rod, and improve the quality of the cut.

If necessary, unique fixing clips are also made (depending on the jigsaw model). When installing them in the housing, copper foil can be used as small pads.

Replacing the rod

In inexpensive jigsaw models, the rod is a thin metal plate of complex shape. If overloaded, it may simply burst. The part is replaceable, some jigsaw models are compatible with others. The device must be carefully disassembled, recording the process in the photo, in order to reassemble it. Then, with the part removed, go to the market or store. Then install the part and apply lubricant.

Replacing brushes

Most models of jigsaws, unless we are talking about frankly budget ones, come with pair of pullers. To replace them, just open the housing: in the rear of the engine, on the contact block, the necessary elements are immediately visible. Repair is simple: old parts are carefully removed, contact pads are cleaned of dust, and wiped with alcohol. After this, it is enough to install new brushes.

Replacing the start button with speed control

You can purchase a replacement part both at specialized points and in stores that sell spare parts for electronic devices. The jigsaw body opens and the corresponding part is freed from the wire leads. This often needs to be done after unscrewing the terminal screws. Modern models do not force you to use a soldering iron. After removing the old one, the new part is installed and connected.

It is better to disassemble the case and remove the button before going to the store to buy exactly the same part for the seat.

A fairly rare failure is the failure of the engine thermal fuse. The part is being replaced. Sparking may be observed, which indicates not only a heavy load, but also wear on the brushes and lack of lubrication. Therefore, periodic maintenance is the key to reliable operation of the jigsaw.

Conclusion

When carrying out any repairs, precautions should be taken. The jigsaw must be unplugged. The first thing you need to check is the serviceability and condition of the power cable, plug, and contact in the socket. Some jigsaw models are equipped with a fuse located in the plug. This element should also be inspected and checked for serviceability.

The overall efficiency of the entire mechanism depends on each of its individual parts. In the case of a modern electric jigsaw, with a relatively complex design, this is exactly the case. Each element of this device is designed to perform a specific function for the sake of the overall result - performing a controlled cut. If problems occur on one of the mechanism components, the performance of the tool may decrease, down to zero. To return your device to service, it is enough to find and eliminate the “weak link”. We will tell you further how to repair a jigsaw with your own hands and reduce further wear of its parts.

Design and principle of operation of an electric jigsaw

To learn how to identify and troubleshoot a mechanism, you must first understand how it works. The numerous components of a jigsaw design may seem quite difficult to understand at first glance. In fact, the principle of operation of this device very simple, especially for those who know at least a little about technology. Next, we will tell you how an electric jigsaw works, outlining the main points in the most popular language, understandable even to an inexperienced reader in electrical engineering.

The mechanism of any electric jigsaw is based on an electric motor, gearbox and rod. These are the main elements that force the file to make the necessary movements. Often a cooling fan and a pendulum mechanism are connected to the engine. The function of power supply and in some models of speed control is performed by a special start button with an electrical circuit. All of the above elements are compactly and securely placed in a plastic case, interacting with each other.

To obtain high-frequency reciprocating movements of the saw blade, the energy supplied to the power tool undergoes significant transformations in its body. Bypassing the start button, electricity passes to the graphite brushes of the motor, causing the rotor to rotate around its axis. The torque is transmitted to a special “gearbox” mechanism, which converts the movement from rotational to reciprocating, directing it to the rod. The final unit is a fastening element that reliably connects the rod to the saw blade, forming a strong movable structure.

Types of faults

Prolonged or improper use of the tool can most likely cause it to break. A device malfunction occurs as a result of excessive contamination, wear of mechanism parts, or a short circuit of the electric motor. Repair of a jigsaw, depending on the nature of the breakdown, boils down to cleaning and lubricating the elements, or completely replacing them. Below, we will look at the most common types of breakdowns.

Mechanical problems

This category includes contamination, wear, or complete breakdown of mechanism parts. The engine of the tool is running, but it is not possible to obtain the required cut. There may be several reasons for mechanical breakdowns that require repair of jigsaws. Here are the most typical ones.

The jigsaw cuts crookedly
A significant deviation of the fork blade away from the intended line is often associated with the saw attachment mechanism or the rod. The reason for this may be severe contamination of the parts or their wear. To correct the situation, you need to remove the parts, clean them with a rag and put them back together. If the problem persists, the stem or fastener should be replaced.

Strong vibration and noise
Strange sounds, uncharacteristic of a running power tool, usually come from a faulty gearbox. This may be due to lack of lubrication, contamination or breakage of the gear teeth. To find out the exact cause and its further elimination, it is necessary to remove the side part of the case and visually inspect the mechanism for the presence of the above problems. In case of breakdown, the mechanism should be replaced with a similar one.

The jigsaw hits when cutting
Regular jolts of the tool during operation may be associated with the pendulum mechanism or the rod. The reason for this is mainly damage to parts, and in rare cases, severe contamination. To repair a jigsaw with a similar malfunction, it should be disassembled, the faulty unit should be identified and replaced with a similar one. If there is no obvious damage, all parts should be completely cleaned and lubricated.

Engine malfunctions

Oddly enough, numerous jigsaw breakdowns occur not only on moving parts, elements interacting with each other. Very often, a device stops functioning (partially or completely) due to the fault of damaged electronics. To identify such faults, you need a special “multimeter” device that determines the characteristics of the current in the device circuit. It is necessary for a complete diagnosis, although some problems can be identified without it.

Jigsaw won't turn on
The complete lack of vital activity of the tool is due to the lack of contact between the motor and the network. The reasons for this problem lie in the wiring or the start button. To identify a malfunction, it is necessary to completely inspect, or better yet, ring the instrument cable and internal wiring. The functionality of the button is checked by connecting the wiring directly to the motor. If the tool works when plugged into the network, then the problem lies there. The faulty contact must be replaced.

Doesn't cut under load
At first glance, the working tool is completely unable to cope with once simple tasks and slows down even on materials of small thickness. Significant loss of power is associated with engine damage. The jigsaw anchor, due to a short circuit, does not create a sufficient rotational impulse, creating the illusion of work. Typically, an instrument with such a breakdown sparks and emits a characteristic burning smell. To accurately determine the location of the short circuit, parts of the stator and rotor of the motor are alternately tested with a multimeter. The solution is to replace the damaged part or the entire motor.

Floating speed and burning smell
When, during operation, the tool periodically loses its strength, reducing its power and accompanied by a burning smell, it is worth paying attention to its wiring. To identify a weak contact, it is necessary to remove the housing cover and visually inspect all wires and their connections for defects. It is better to do this using a multimeter, paying attention to the start button and the motor windings. To restore the integrity of the circuit, the conductors should be replaced or the charred contacts should be cleaned.

Sparking brushes during operation
The abundant formation of sparks that occurs in the commutator area during operation of the tool can be associated not only with a malfunction of the engine, but also with a defect in the graphite brushes. IN modern world, this component is one of the most frequently replaced parts when repairing equipment, so many jigsaws have special grooves for quick and convenient removal. You can make the replacement yourself. It is enough to disconnect the old brushes from the contacts and connect new ones in their place.

Replacing the rod

The procedure for removing a damaged rod and installing a new one is quite trivial and boils down to a banal disassembly of the tool. Depending on the design of the jigsaw, you can access the element by unscrewing the front panel or the side panel, if the first is missing. The faulty rod is removed and a new one is installed in its place. When installing, pay attention to the moving metal parts located on the base of the rod. They must be positioned in such a way that they fit into the grooves of the upper fastening and the metal frame that serves as the base of the rod. The assembled structure must be generously lubricated with a thick lubricant such as Litol-24.

A more visual demonstration of replacing the rod can be seen in the video below about repairing a fiolent jigsaw with your own hands.

Replacing the saw holder

Replacing some types of fasteners is much easier than finding these parts. To perform a similar operation with block and screw clamps, you do not even need to unscrew the tool body. Saw holders of this type are attached to the end of the rod using one or two screws, which makes it quite convenient to change them. In the case of some screw fasteners, replacement will require removing the rod to more conveniently and securely fix the holder.

The video below about repairing a jigsaw with your own hands clearly demonstrates the process of replacing the shoe type fastening.

If things are relatively simple with simple saw holders, then replacing a quick-clamping one can cause some difficulties, especially for an inexperienced craftsman. Let's start with the fact that these types of fastenings, according to the location of the levers, are divided into radial, lateral and frontal. The first type is the most common and spare parts for its repair can be found, but the last 2 are unique, which can be ordered directly from the manufacturer. In the case of a radial type of fastening, you can purchase a repair kit and try to sort it out yourself, but it would be best to buy it assembled, along with the rod.

Replacing brushes

Due to abrasion or burning of contacts, jigsaw brushes very often become the main contenders for replacement. In some models of power tools, this operation does not require removing the housing and occurs simply by unscrewing a pair of bots. Unfortunately, the quick access function is not provided on all models, so we will consider a more common option.

First of all, you need to gain access to the electric motor. To do this, we disassemble the housing or remove a certain part of it. Next, in the collector area, we look for brushes and study the principle of their fastening. On different models tools, fastening of these elements can vary significantly. In some places they are pressed against metal plates, in others they are latched with special levers, and sometimes they are even held in place by the body of the instrument. The replacement process itself is not some incredibly complicated DIY jigsaw repair. It is enough to carefully remove the defective brushes and replace them with new, identical ones. This process is clearly demonstrated in the following video.

Replacing the start button

When the tool stops responding to the power supply command, the first thing to do is check the start button by ringing it with a multimeter. Having confirmed that the element is faulty, disconnect its contacts and remove it from the housing. At this stage, there are 3 options for the development of the event:

• You can try to disassemble the button and repair it yourself.
• Connect the wires directly and start the tool by plugging the plug into the outlet.
• Look for a suitable button in specialized stores or markets and replace it.

If you choose the latter option, all the difficulty will be in the search, since the trigger must be absolutely identical to the standard one. Perhaps you will be lucky and the necessary element will be found in the nearest store. It all depends on the location and model of the instrument. The installation process fully corresponds to the removal, only in reverse order. We connect the wires to the contacts and tighten the device body.

If you want to repair the jigsaw button yourself, we recommend that you watch the video below, which demonstrates this process in great detail.

Tool prevention

The long service life and constant efficiency of the tool depend not only on the characteristics of its operation, but also on timely care of its mechanism. Regular preventative measures will significantly reduce the wear of parts, reducing the likelihood of serious breakdowns.

Carrying out such a procedure requires only a screwdriver, a piece of rag for cleaning and a little grease. The whole process takes no more than an hour and consists of disassembling the jigsaw and carefully cleaning its parts. The gearbox and rod assembly must be cleaned and lubricated most thoroughly. Prevention should be carried out as the tool becomes dirty, based on the frequency of its use.

Among the hand tools used in the household, the most popular is the jigsaw. This is an electrically driven device designed to produce a curved cut.

Demand determines supply. The power tool market is represented by a wide range of both household and professional models from domestic and foreign manufacturers. Any equipment requires maintenance and repair if necessary.

Using examples of real breakdowns and methods for eliminating them presented in this article, the user will learn about repairing jigsaws from different manufacturers generally.

The design of electric jigsaws and their malfunctions

The design of jigsaws from different companies differs little. It consists of a body, a sole, a saw blade, a cutting tool mechanism, a gearbox and an electric motor that drives the working part of the tool.

The difference in models from one manufacturer or another lies in the design features of some components. It is natural that the malfunctions and the reasons for their occurrence are also identical.

Knowledge of the most common failures of power tools and preventive measures to prevent them will help both the novice master and the experienced professional.

Typical failures of electric jigsaws include:

1. Sawing curvature.
2. Change in shape or destruction of the support roller.
3. Breakage of the cutting tool mounting unit.
4. Damage to the gear wheels of the gearbox.
5. Destruction or bending of the support rod.
6. Broken teeth on the jigsaw collet.
7. Early wear of the armature worm gear.

Typical power tool failures and measures to prevent them

The jigsaw is designed to perform rough curved cuts, so there is no point in talking about ideal sawing. Although this indicator is also different in hand tool models from different manufacturers. When using cheap models, they don’t pay much attention to this, and the cut turns out completely crooked. You need to deal with this in service centers, but you can try to get rid of the curvature at home.

The support roller may break if poor quality saw blades or dull tools are used. Use of cutting tools in inappropriate load conditions. The result may be jamming or cutting of the support roller.

To avoid such a problem, you need to use well-sharpened cutting blades of acceptable quality, observing optimal cutting conditions and following the manufacturer’s recommendations.

As a rule, almost all models of jigsaws are equipped with a tool-free saw blade fixation unit. This simplifies the process of changing cutting tools. But operating the mechanism in conditions of constant dustiness leads to wood shavings getting into it, and this leads to failure of the device.

In order to avoid damage to the unit, it must be constantly cleaned of dust and lubricated with a special compound such as WD-40. During operation, you must use a vacuum cleaner by connecting it to the tool.

Failure of gearbox elements is a consequence of wood dust entering through the ventilation holes. Here, as in the previous case, you cannot do without a dust collector.

Breakage or bending of the support rod occurs during careless use of the power tool. This can happen when it falls or an unintentional collision of the jigsaw body, directly the support rod, with protruding elements of the surfaces being processed.

The destruction of a tooth on the collet of an electric jigsaw can only occur through the fault of the performer. This is caused by an attempt to inadvertently tighten a cutting blade that is not fully inserted.

The armature worm gear will not last long if you start the cutting process before the tool motor reaches optimal power. To extend the service life of the mechanism, do not start work before reaching full engine speed.

Jigsaw Interskol: correction of sawing curvature

It is worth paying attention to the Interskol jigsaw domestic production. It is produced in Izhevsk. For household use this is a completely acceptable option. It has many positive qualities, and the most impressive is its low cost. But there are also disadvantages.

Replacing the quick release saw blade mount

This is the curvature of the saw. What is the problem, and is it possible to get rid of it? The culprit was the quick-release fastening of the file. The fact is that it is designed for saw blades of maximum thickness. All cutting tools of smaller thickness simply dangle in the mount.

How to get out of this situation? You need to replace the quick-release mount with a simple device with regular bolts. It's not difficult to make. You need to take a square rod, cut two blanks, drill holes in them and connect them with two M5 bolts and nuts. The procedure for attaching the saw blade will become somewhat more complicated, but the tool will produce an even cut.

Refinement of jigsaw design

In addition, you can modify the design of the tool itself and limit the movement of the file in the transverse plane.

To do this you need:

• take sheet aluminum and cut the plate to the size of the jigsaw sole;
• In the front part of the workpiece, it is necessary to make a cut to the size of the working area of ​​the cutting tool. File all edges, make bevels on the inner longitudinal edges of the cutout;
• You need to cut a plate from plexiglass to the size of the working area of ​​the saw blade. File all sharp edges and make reverse bevels on the outer longitudinal edges;
• The aluminum plate must be marked for installation on the jigsaw base. Drill holes and make chamfers for installing countersunk screws;
• a piece of plexiglass must be inserted into an aluminum plate, having first made a cut at its location.

Now, during operation, the saw blade will be limited in transverse movement almost in the cutting zone, which will give it even greater straightness.

Jigsaw Diold: a budget option for the household

Another, no less popular manufacturer of domestic power tools is the Smolensk company Diold. Jigsaws are distinguished by their low price and fairly decent quality. For home work, this is a completely suitable budget option.

Support roller repair

It also has points that are worth paying attention to. The first is the support roller. Over time, which is about a year, he begins to lose round shape. The reason is the material of the roller or the technology of its manufacture. It lacks hardness.

Its repair consists of replacement. Still, it is better not to reinvent the wheel, but to purchase an original roller from the manufacturer or take the tool to a service center, especially if it is under warranty.

If this option is not suitable or is not feasible, then you can revive the jigsaw using improvised means. To do this you will need a regular M5 bolt with a nut. In this case, the bolt will serve as an axis, so the thread on it needs to be ground off, and the nut with a roller, in which a groove needs to be cut along the generatrix according to the thickness of the saw blade.

It is ideal to do this on lathe, but you can also use a tool that is at hand, for example, a drill and an angle grinder disc. The disk must be clamped in a vice, the bolt and nut must be clamped into a drill and a groove must be cut. The repair option is not ideal, but it has the right to life, since it has been tested in practice.

Start Button Maintenance

Another nuance in using a Diold jigsaw is that wood dust gets into the start button. This happens due to the lack of tightness, and dust getting inside the button prevents the passage of current. The solution to the problem is to periodically, at least once a year, clean the contacts.

Metabo jigsaw: ideal in quality, but difficult to repair

One of the best jigsaws on the world market are models from the German company Metabo. Everything about it is good. High power, aluminum body, pendulum device. In addition, the tool is equipped with electronics that allow you to configure the jigsaw to individual programs for each type of cut. And the cut is simply perfect both in quality and straightness. The Metabo power tool is the best jigsaw to date.

But not eternal. Breakdowns happen here too. The reasons can be very different. But as practice has shown, the weak point is the mechanics. After significant loads, and in particular, sawing metal, it may fail.

As a rule, the axle on the bearing bracket, lever and rod do not support. To restore the instrument, it is better to purchase all original spare parts and carry out the assembly at a service center by specialists.

At self-assembly When using a Metabo jigsaw, it is imperative to apply Castrol LMX lubricant to all rubbing surfaces with the addition of RiMET grease in a ratio of 3:1.

Jigsaw Fiolent: main reasons for failure

Let's consider another budget option for a jigsaw - the Crimean Fiolent. This is a completely acceptable model both in price and quality. There are two problems with using a jigsaw. This is a possible failure of the rod due to incorrect handling of the tool and insufficient or improper lubrication.

Replacing the rod

In the first case, to avoid this damage, it is enough to handle the tool carefully and carefully. But if this happens, you will have to replace the damaged rod. To do this you need:

1. Remove the housing cover by unscrewing the 4 screws.
2. Remove the washers from the rod rectangular shape and holding guides.
3. Unscrew the 4 bolts and remove the mechanism cover. Below it is the flywheel and the rod itself.
4. Unscrew 2 screws each, remove the lower and upper rod holders. The latter has a spring, so you need to remove it carefully.
5. Remove the damaged rod with guide washers.
6. Lubricate the flywheel and eccentric with special gearbox lubricant.
7. Place the guide washers on the new rod and install it in place.
8. Attach the saw blade holder to the lower part of the rod.
9. Install the upper and lower holders, screw on the mechanism cover and install washers and retaining guides.
10. Insert the cutting tool and test the jigsaw at idle and under load. If the check does not reveal any deviations, install the housing cover.

Tool lubrication

In the second case, everything is much more serious. It would seem that what is so difficult about lubrication? But due to the fact that the tool constantly operates in extreme conditions, wood dust cannot be avoided getting inside the device; service work has to be carried out according to the intensity of use, but at least once a year.

All mating parts and assemblies need to be lubricated. To do this, you need to disassemble the jigsaw. But if in the first case you, for example, limited yourself to only dismantling the rod, now we disassemble the tool completely and smear all the rubbing surfaces of the parts.

For lubrication, the manufacturer offers Litol 24, but it will not work in a jigsaw gearbox due to its thick consistency, so it is usually lubricated with oils. You can combine Litol 24 with graphite-containing lubricant Feol 2U in a ratio of 3:1.

Finalization of the design

However, it should be taken into account that now the fluidity of the lubricant mixture is higher, and after some operating time it will begin to enter the engine rotor. The reason for this is the left-hand transmission. As the rotor rotates, the lubricant mixture is captured by the teeth and fed to the rotor as if through a screw. The oil separator installed inside the electric motor housing does not perform its functions. In theory, it should reject the incoming mixture, but in practice this does not happen. This is evidence of the imperfection of the design proposed by the manufacturer.

To avoid this problem, some modification needs to be done. Or rather, place the oil separator not inside, but outside the electric motor housing. At the same time, in order for the oil separator snail to work and reject oil, it is turned over.

One more nuance. The diameter of the mounting hole is Ø 9 mm, and the diameter of the outer part of the oil separator is Ø 9.2 mm - it will ideally block the passage for the lubricant mixture. But when installing it, you need to apply a certain force and an attachment in the form of a pipe of a suitable size.

In addition, it is advisable to install a dust shield on the rear armature bearing. It will protect it from wood dust and extend its service life.

After this, you need to assemble the lubricated jigsaw and test it for functionality. After operating for 10 hours, you need to check the tool for grease getting into the motor housing. If everything is done correctly, then this option is excluded.

Bosch jigsaw: high price and expensive repairs

And of course, Bosch. Power tools from this manufacturer are distinguished by high quality components, assembly and a long service life, provided they are treated with care. It also has a drawback - the price. Moreover, both the product as a whole and spare parts are expensive.

It should be noted that Bosch tools practically do not break, but there are some nuances that appear during long-term use. For example, wear of the electric motor brushes, failure of the speed controller or saw blade fastening device. There are even more complicated accidents, failure of the rod or armature, but this is most likely due to incorrect handling.

As in the case of Metabo, Bosch jigsaws are best repaired at service centers. They will install original spare parts and provide a guarantee for the repairs performed. But this is an expensive pleasure.

After reading the article, the user gained theoretical knowledge about failures in the operation of jigsaws. Now, in the event of a breakdown, he will be able to determine the cause and make the right decision, and maybe even perform minor repairs.

With proper use and storage, a jigsaw can easily serve the entire period stated by the manufacturer. But in any case, nothing is eternal.

There is no need to throw away the tool after its stated service life. Experts advise carrying out several simple maintenance operations that will protect the tool from damage, and it will last for quite a long time. So, you need:

Replace the current supply wire to avoid short circuit and damage. electric shock due to insulation damage;

Replace the brushes in the electric motor - the old ones are most likely already worn out;

Renew the lubrication of mechanisms (especially bearings);

Clean the insides of the jigsaw from wood and other dust.

If you have no time or are unable to do these manipulations yourself, you should take the tool to a service center. It is important to note that self-service (disassembly and replacement of parts) of the system before the end of the warranty will result in the latter being automatically voided.

- Additional convenience will be provided by the SDS saw blade fastening system, which allows you to change attachments without effort and additional accessories

- A jigsaw will only work in full accordance with its passport specifications when high-quality accessories are selected for it. So, for example, if you work with chipboard, then using a metal file will not allow you to achieve the desired cut quality

To make the work easy, the result to be of high quality, and the tool to last a long time, you must adhere to the following rules:

How to extend the service life of a jigsaw, a little advice, which consists of lubricating the main elements of the jigsaw with liquid machine oil before each work.

Recently, one of my friends complained that in just one year of work, some of the working elements of his jigsaw were badly worn out. This is in particular the rod roller and its guide, the saw blade guide roller, and the files themselves, according to my friend, wear out very quickly.

When I talked to him about this in more detail, to my great surprise, I learned that it turns out that he did not lubricate the indicated worn elements at all before work.

For me, this was a complete revelation, since ever since I bought my jigsaw, ten years ago, I always lubricate it before every job. Perhaps this is largely why it has served me very well all these years and without any problems.

By the way, before writing this article, I was not too lazy to re-read the operating instructions for my jigsaw. And what’s interesting is that I really didn’t find any instructions there to lubricate the main working elements of the jigsaw every time before the next job. This may not be indicated in the instructions for other jigsaws.

However, I think that any person who understands technology understands that any tribo-coupling (friction coupling) necessarily needs lubrication.

It was this fact that prompted me to write this article.

Of course, it is possible that seasoned DIYers who are well versed in technical issues This article will not be particularly interesting, but, nevertheless, for other readers, for example, for beginning DIYers, it may well be not only interesting, but also very useful.

So, my advice is to lubricate the main working elements of the jigsaw with liquid machine oil before each job. This will help to significantly extend the service life of both these elements (including files) and the entire jigsaw as a whole.

I will show you the lubrication process using my jigsaw as an example.

First, lubricate the guide for the rod roller. The rod is a part that performs a reciprocating movement during the operation of the jigsaw, and the file is attached directly to the end of which.

For lubrication, it is enough to apply three or four drops of machine oil to the guide.

Then we lubricate the slot of the guide plates for the saw. This slot serves to guide the movement of the file and there is quite intense friction in it.

By the way, in many designs of modern jigsaws, instead of guide plates for the saw, there are guide rollers. Naturally, in this case it is necessary to lubricate the roller axis and the guide slot itself for the file.

And finally, lubricate the file itself by dripping a few drops of oil onto its teeth along the entire length. Moreover, it is advisable to do this not only when sawing metal, but also when sawing wood, since it significantly extends the service life of the file itself.

After we have applied the specified lubrication, it is advisable to let the jigsaw idle for 3-4 seconds, gradually increasing the engine speed so that the oil is well distributed over all rubbing parts.

Well, then you can get to work!

It is advisable to lubricate this before each time you start working with a jigsaw. Usually one time is enough, but if you have to work for a long time, then you can repeat such a lubricant once or twice during the work.

In addition, I would like to add that with such lubrication, small chips and dust intensively adhere to the rubbing parts of the jigsaw. Therefore, after work, you must thoroughly clean the working parts of the jigsaw.

For general cleaning, a regular paint brush works very well.

And for more detailed cleaning of rubbing surfaces from dust and shavings mixed with oil, a used toothbrush is suitable.

The specified measures for lubricating and cleaning the jigsaw will undoubtedly help to significantly extend the life of your tool. I strongly advise all DIYers who often have to work with a jigsaw not to neglect them!

Well, that's all for me!
Wishing everyone long and trouble-free operation of your power tool!
