Do-it-yourself jigsaw repair 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 will be able to eliminate such a malfunction.
Consider what happens to the 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 wearer's hand. The presence of such a mechanism of operation causes increased wear of individual structural elements. These are the guide roller as well as the stem sleeves. Other typical situations include:
Extremely high load... Occurs with excessive diligence of the sawyer, which puts a lot of pressure on the horizontal feed. In inexpensive models, the file can damage the fragile holder. Another common breakdown is stem failure, as a result of which the jigsaw ceases to fulfill its purpose and the saw does not move.
Lack of maintenance... Causes increased bearing wear, abrasion of the cam block in some models, gears becoming unusable.
Failure of electrical components systems. This is a start button that is often associated with an engine speed governor.
Long run time... Affects the state of the current-collecting surfaces of the motor, abrades the brushes. The repair consists in the replacement of the corresponding parts.
Periodic maintenance - cleaning the insides of small sawdust, replacing brushes and grease - will extend the life of the electric jigsaw and prevent its failure.
Many modern jigsaws are equipped with bells and whistles, which are their weaknesses. For example, some models often require repair of the file attachment, due to the presence of functions such as:
Quick clamp, which does everything for the owner of the tool: just pull the lever, place the blade and work. Over time, the structure loosens, the fastening parts become unusable. Unfortunately, most of these clamps cannot be repaired, they can be completely replaced.
Lightweight screw mount - a real problem for owners of cheap and medium-priced instruments. The rod end, made of weak alloys, has low strength, splits, bolts break seats. The repair consists only in the handicraft of the corresponding product from durable steel, since each line of cheap tools often has its own configuration of the file holder.
If the jigsaw has a classic screw fastening of the saw, then it will not be difficult to repair it. It is a durable and time-tested design, you can use screws for a Phillips screwdriver or a wrench. The clamping units are standard, it is not difficult to find a replacement for an extremely worn part. There is a problem with thread wear, but in this case, you can cut a new one.
The tool is easy to disassemble. The body is divided into two halves, allowing access to all parts of the mechanics. The first step is to remove dirt and replace the grease, after which you can start repairing.
Let's note right away that there are no spare parts in stores. You can find the corresponding part by purchasing a broken tool at the flea market. Parts from other devices and mechanisms are often suitable. For example, jigsaws with a round stem are the easiest to repair. A round bushing is selected, if necessary, the inner diameter is increased by packing on a cone. This repair allows you to eliminate the runout and backlash of the rod, to improve the quality of the cut.
If necessary, unique fixing clips are made (depending on the jigsaw model). Copper foil can be used as small spacers when installed in a case.
In inexpensive jigsaw models, the stem is a thin metal plate of complex shape. Under excessive load, it can simply burst. The part is replaceable, some jigsaw models are compatible with others. The device must be carefully disassembled, fixing the process in the photo in order to reassemble. Then, with the part removed, go to the market or store. Then install the part and apply grease.
For most models of jigsaws, if we are not talking about frankly budgetary ones, the kit comes with a pair of pullers... To replace them, it is enough to open the case: in the back of the engine, on the contact block, the necessary elements are immediately visible. Repair is elementary: old parts are carefully removed, contact pads are cleaned of dust, wiped with alcohol. After that, it is enough to install new brushes.
You can purchase a replacement part both in specialized points and in stores selling spare parts for electronic devices. The body of the jigsaw opens, the corresponding part is freed from the wire leads. This should often be done after unscrewing the terminal block screws. Modern models are not forced to use a soldering iron. After removing the old, the new part is installed and connected.
It is better to disassemble the case and dismantle the button before going to the store in order to buy exactly the same part in the seat.
Jigsaw start button
Rather rare breakdowns include failure of the engine thermal fuse. The part is replaced. Sparks can be observed, which indicates not only a heavy load, but also wear of the brushes and a lack of lubrication. Therefore, periodic maintenance is the key to the reliable operation of the jigsaw.
When carrying out any repairs, precautions should be taken. The jigsaw must be disconnected from the mains. The first thing to check is the health and condition of the power cable, plug, contact in the socket. Some jigsaw models are equipped with a fuse located in the plug. This element is also worth inspecting and checking for serviceability.
The jigsaw is designed for cutting various materials. The design is simple, but breakdowns are also inevitable. Do-it-yourself jigsaw repair usually consists in replacing a blade that has worn out, fixing units, and a support roller. In the event of a breakdown of the motor, it is recommended that the device be returned to the master for repair.
Jigsaw device diagram.
How to determine if the jigsaw needs repair or preventive measures? There are a number of signs to look out for:
the body began to heat up too much during operation;
when switching on and further operation, uncharacteristic sounds are heard;
collector brushes sparkle;
the engine cannot be adjusted, there are other problems.
Replacing the jigsaw rod guide bushings.
When the listed symptoms are found, you must immediately turn off the jigsaw, then inspect it, determine the malfunction. All types of such breakdowns can be conditionally divided into 2 large groups.
Electrical breakdowns:
A factory defect in the form of a rotor breakdown (cannot be repaired, you must contact the service center).
The stator or rotor gets very hot during operation, there is a melting on the insulation. The reason is dust ingress, pollution, incorrect loading.
The brushes are worn out (replaced).
If the speed regulator does not work, then it needs to be replaced. It is best to contact a master.
Breakdown of the mechanical part of the jigsaw:
The internal structure of the jigsaw.
The gear has been found to have wear or deformation of the teeth. It is possible to repair the jigsaw, a complete replacement of the gear is required, in the future it is necessary to carefully monitor the loads, the correct choice of the blade.
The stem breaks, there are kinks on it. It is required to repair the jigsaw by replacing the stem, in the future, choose the right saws in accordance with the type of material. For example, for wood or metal, take only specially designed devices.
The balancers that guide the rollers are worn out. Need to replace the balancers, in the future you need to monitor the loads.
If the bearings are worn out, they are replaced. It is best to contact a master.
Other types of breakdowns can also be observed. For example, a strong impact may cause the body to split.Do not drop the jigsaw, in this case, you can damage other parts of it. It is best not to fix engine breakdowns with your own hands, but immediately contact the service center. Replacing worn parts can be handled by yourself... To do this, the manufacturer provides instructions, following it, you can easily cope with the work yourself.
The main characteristics of household jigsaws.
How do I repair when I find a problem? The support roller can break if the load is applied too much, i.e. cutting technology is broken. The file is attached to this particular roller if it is broken, but the file cannot be used. To prevent a breakdown from occurring:
Use only high quality hacksaw blades.
Blunt files must not be used.
Hacksaw blades should be selected only in full accordance with the purpose. For example, for metal, only the fabric is used that is intended specifically for this material.
If the roller is not replaced when it is broken, the equipment may jam during operation. The repair will begin not with replacing the roller, but with cutting it with another tool and then replacing it. The renovation itself is not too difficult. The support roller with traces of damage must be removed, and then replaced with a new one corresponding to the used jigsaw model.
The blade fixation unit usually breaks when a large amount of dust gets on it. During operation, dust is not uncommon, therefore, for prevention, it is regularly required to clean the surface of the fasteners. Over time, the situation will get worse, the equipment may completely fail. Repair usually consists of completely replacing the retainer.
To prevent malfunctions, you can carry out regular preventive maintenance.
It consists in performing a number of actions:
The assembly must be constantly cleaned and then lubricated.
During work, you must use a dust collector, which will prevent a large amount of dust from getting on the tool.
Repairs may be required in other cases as well. Breakdowns can be associated with physical wear and tear of the equipment.
Replacement of certain parts is required in the following cases:
Jigsaws are usually easy to repair. The job is to replace the worn out part. To extend the service life of the equipment, it is necessary to follow the operating rules and carry out preventive maintenance. In case of more complex breakdowns, it is better to immediately contact the master.

Jigsaws are an indispensable tool for every home craftsman. This simple device can cut everything - metal profiles, timber with boards, and plastic. Everywhere they are not adapted. Like the grinders, jigsaws for 10-12 years almost did not get used to almost any changes. Even the laser line appeared on them back in 2003.
This jigsaw (from the Dutch in China) Skil 1061AA is not a very common model. Belongs to the initial class of jigsaws. A decent power of 800 W suggests that a tool at this price is not only unfinished, but focused on rough work, and one should not expect accuracy from it.
Skil 1061AA, traditionally for all jigsaws, is equipped with a pendulum stroke for fast and rough cutting, speed control.
The accuracy of the laser illumination is poor. By the way, it is powered from the mains, not from batteries, as is the case on many models with "pointers".
Another thing that distinguishes the Skil 1061AA is its rough, heavy-duty outsole, which again suggests that the tool is not for jewelery work.
In general, the impressions are twofold. On the one hand, it is not an expensive and powerful tool. And extremely tenacious. On the other hand, after more precise competitors in its niche, for example, STERN JS-100KL, it seems to be somewhat rambling and bulky. And the fastening of the files leaves much to be desired - it is made at the level of “cheap Chinese”.
Skil 1061AA specifications:
Saw movement frequency 800 - 3000 strokes / min
Sawing capacity in wood 100 mm
Sawing capacity aluminum 10 mm
Sawing capacity of steel 4 mm

My review is short: use it for wear where an expensive tool is a pity. Firewood, slabs, boards, beams, plywood for rough work, after all, you also need to cut something if you intend to saw with a jigsaw (by the way, it is cheaper than a chain saw - there are files for longer than chains, it does not eat oil).
Among the hand tools used in the household, the jigsaw is the most popular. 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 technical maintenance and repair if necessary.
Using examples of real breakdowns and methods for their elimination presented in this article, the user will learn about the repair of jigsaws from different manufacturers in general.
The design of jigsaws from different companies is not much different. It consists of a body, a sole, a saw blade, a cutting tool mechanism, a gearbox and an electric motor that drives the working body of the tool.
The difference in the models of a particular manufacturer lies in the design features of some units. It is natural that the malfunctions and the reasons for their occurrence are also identical.
Knowing the most common power tool failures and the preventive measures to prevent them will help both the novice DIYer and the experienced professional.
Among the typical failures of electric jigsaws are:
Sawing curvature.
Change in shape or destruction of the support roller.
Breakage of the cutting tool attachment.
Damage to the gears of the reducer.
Destruction or distortion of the support rod.
Broken teeth on the jigsaw collet.
Early wear of the armature worm gear.
The jigsaw is designed to perform rough curvilinear cuts, so it's not worth talking about the ideality of sawing. Although in models of hand tools from different manufacturers, this indicator is also different. When using cheap models, they don't pay much attention to this, and the cut turns out to be completely crooked. You need to deal with this in service centers, but you can try to get rid of the curvature at home.
The platter roller can break if you use poor quality saw blades or a blunt tool. The use of a cutting tool in an inappropriate load condition. This can result in a jammed or cutting of the platter roller.
To avoid such a problem, you need to use well-sharpened cutting blades of acceptable quality, observing the optimal cutting conditions and following the recommendations of the manufacturer.
As a rule, almost all models of jigsaws are equipped with a toolless saw blade fixation unit. This simplifies the process of changing cutting tools. But the operation of the mechanism in conditions of constant dustiness leads to the ingress of wood chips into it, and this leads to the failure of the device.
In order to exclude a breakdown of the unit, it must be constantly cleaned of dust and lubricated with a special compound such as WD-40. During operation, it is necessary to use a vacuum cleaner by connecting it to the tool.
Failure of the gearbox elements is the result 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 the careless use of the power tool. This can happen when it falls or unintentionally collides with the jigsaw body, directly the support rod with protruding elements of the machined surfaces.
Tooth decay on the collet of an electrically powered jigsaw can only occur through the fault of the performer.This is the result of an attempt to inadvertently tighten the not fully inserted cutting blade.
The armature worm gear will not last long if the cutting process is started before the tool motor reaches its optimum power. To prolong the life of the mechanism, do not start work before reaching full engine speed.
It is worth paying attention to the domestic production of the Interskol jigsaw. It is produced in Izhevsk. For domestic use, this is a perfectly acceptable option. It has many positive qualities, and the most impressive is its low cost. But there are also disadvantages.
This is the curvature of the cut. What is the problem and can you get rid of it? The blame was the quick-release fastening of the file. The fact is that it is designed for the maximum saw blade thickness. All thinner cutting tools in the mount just dangle.
How to get out of this situation? It is necessary to replace the quick-release mount with a simple device with ordinary bolts. It is not difficult to make it. You need to take a square rod, cut off two blanks, drill holes in them and connect with two M5 bolts with nuts. The procedure for attaching the saw blade will be somewhat more complicated, but the tool will produce an even cut.
In addition, you can modify the very design of the tool and limit the movement of the file in the transverse plane.
take sheet aluminum and cut the plate to fit the sole of the jigsaw;
in the front part of the workpiece, it is necessary to make a cutout according to the size of the working area of the cutting tool. File all edges; make bevels on the inner longitudinal edges of the cutout;
from plexiglass, you need to cut a plate 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 its installation on the sole of the jigsaw. Drill and chamfer holes for the installation of countersunk head screws;
a piece of plexiglass must be inserted into an aluminum plate, after having made a cut at the place of its position.
The saw blade will now restrict its lateral movement in the cutting area during operation, which will give it even more straightness.
Another, no less popular manufacturer of domestic power tools, is the Smolensk company Diold. Electric jigsaws are distinguished by their low price and rather decent quality. For homework, this is a perfectly suitable budget option.
It also has points worth paying attention to. The first is the support roller. Over time, and this is about a year, it begins to lose its round shape. The reason is the material of the video or the technology of its production. It has insufficient hardness.
Its repair is to replace it. Still, it is better not to reinvent the wheel, but to purchase an original video from the manufacturer or take the tool to a service center, especially if it is under warranty.
If this option is not suitable or impracticable, then you can reanimate the jigsaw with the help of available tools. To do this, you need a regular M5 bolt with a nut. In this case, the bolt will serve as an axis, so you need to grind off the thread on it, and the nut with a roller, in it along the generatrix it is necessary to cut a groove along the thickness of the saw blade.
It is ideal to do this on a lathe, but you can also use a tool that is at hand, such as a drill and an angle grinder disc. The disk must be clamped in a vice, the bolt and nut - in the drill and cut into a groove. The repair option is not ideal, but it has the right to life, as it has been tested in practice.
Another nuance in using the Diold jigsaw is the ingress of wood dust 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 will be periodic, at least once a year, cleaning the contacts.
One of the best jigsaws on the world market are the models of the German company Metabo. Everything is good in him. High power, aluminum body, pendulum device. In addition, the tool is crammed with electronics, which allows you to customize the jigsaw to individual programs for each type of cut. And the cut is just perfect both in quality and straightness. The Metabo power tool is the best jigsaw today.
But not eternal. Breakdowns happen here too. The reasons can be very different. But as practice has shown, the weak point is mechanics. After significant loads, and in particular, cutting metal, it may fail.
Typically, the axle on the bearing bracket, arm and stem will not support. To restore the tool, it is better to purchase original spare parts, and assemble them at a service center by specialists.
When self-assembling the Metabo jigsaw, it is imperative to apply Castrol LMX grease to all rubbing surfaces with the addition of RiMET grease in a ratio of 3: 1.
Consider another budget option for a jigsaw - the Crimean Fiolent. This is a perfectly acceptable model both in terms of price and quality. There are two problems in the operation of a jigsaw. This is a possible failure of the stem during improper handling of the tool and insufficient or illiterate lubrication.
In the first case, in order to avoid this damage, it is enough to carefully and carefully handle the tool. But if this does happen, you will have to replace the damaged stem. For this you need:
Remove the housing cover by unscrewing 4 screws.
Remove the rectangular washers and retaining rails from the stem.
Unscrew 4 bolts and remove mechanism cover. Below it is the flywheel and the stem itself.
Unscrew 2 screws each, remove the upper and lower stem holders. The latter is with a spring, so you need to clean it carefully.
Dismantle the destroyed stem with guide washers.
Lubricate the flywheel and eccentric with a special gear lubricant.
Put the guide washers on the new stem and install in place.
Attach the saw blade holder to the bottom of the stem.
Install the upper and lower holder, screw on the mechanism cover and install the washers and retaining rails.
Insert the cutting tool and test the jigsaw at idle speed and under load. If the check shows no abnormalities, install the housing cover.
In the second case, everything is much more serious. It would seem, what is difficult about lubrication? But due to the fact that the tool constantly works in extreme conditions, the ingress of wood dust into the device cannot be avoided, it is necessary to carry out service work according to the intensity of operation, 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, for example, you limited yourself only to dismantling the stem, now we disassemble the tool completely and re-lubricate all the rubbing surfaces of the parts.
For lubrication, the manufacturer offers Litol 24, but it will not work in the jigsaw gearbox, due to its thick consistency, therefore, as a rule, it is lubricated with oils. You can combine Litol 24 with Feol 2U graphite grease in a ratio of 3: 1.
However, it should be borne in mind 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 left-hand drive. When the rotor rotates, the lubricant mixture is captured by the teeth and is fed to the rotor like a screw. The oil separator installed inside the motor housing does not fulfill its function. In theory, it should throw away 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 work needs to be done. Or rather, put the oil separator not inside, but outside the motor housing.At the same time, in order for the oil separator snail to work and discard oil, it is turned over.
One more nuance. The bore diameter is Ø 9 mm, and the diameter of the outer part of the oil separator is Ø 9.2 mm - it ideally blocks the passage for the lubricant mixture. But when installing it, you need to apply a certain effort and a nozzle in the form of a pipe of a suitable size.
In addition, it is advisable to install a dust washer on the rear bearing of the armature. It will protect it from wood dust and extend its service life.
After that, you need to assemble the oiled jigsaw and test it for performance. After 10 hours of operation, the tool should be checked for grease penetration into the motor housing. If everything is done correctly, then such an option is excluded.
And of course Bosch. The power tool of this manufacturer is distinguished by the high quality of components, assembly and a long service life, provided that it is treated with care. He also has a drawback - the price. Moreover, both the product as a whole and the spare parts are expensive.
It should be noted that the Bosch tool practically does not break, but there are some nuances that appear during long-term use. For example, wear on the brushes of the electric motor, failure of the speed controller or the device for holding the saw blade. There are accidents and more complicated ones, failure of a rod or an anchor, but this is, rather, from incorrect handling.
As in the case of Metabo, Bosch jigsaws are best repaired at service centers. There they will install original spare parts and give a guarantee for the repair performed. But this is an expensive pleasure.
After reading the article, the user gained theoretical knowledge about jigsaw failures. 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.
Good afternoon, masters! I need your advice.
The Skil 4260 jigsaw has broken. Broken part: U-shaped piece, inside which there is a gear and the whole mechanism of the file holder. There are three tabs on it, the middle one is broken.
The service center said that all this structure is assembled and will cost more than 1000r. Can you please tell me if it is possible to find this U-shaped plate separately for sale somewhere (in St. Petersburg).
From the picture, it is also not clear what kind of article it has and it comes separately or assembled
Your masters got sick, however, just like ours in the Moscow Boshevsky service. In reality, such a spare part costs 600-something rubles in a store specializing in the sale of Bosch tools, spare parts and consumables (and Skill, respectively). I know because I changed it myself in my 4260. Here in the spring I wrote about it: ”> Paying for a spare part (especially a unit in which, as it turned out, there is something to break apart from what happened to me) 50% of the price of a new jigsaw is, in my opinion, bestiality. And if you take it to a service center, then the old repaired one turns out to be 50 rubles cheaper than the new one. Plus for the diagnosis, to give an answer to how much the repair will cost, they took 120 re - so it turns out that the old one is generally more expensive than the new one. I'm losing weight, in short.
I broke the part into which the canvas was inserted, and unfortunately deciding that there was nothing else to break, I threw out all this junk from the old assembly, with the exception of the plastic parts of the clamp and brass bushings (in your picture, there are pointers from number 836) in which a large gearwheel is spinning. ...
And in vain. Recently I had to work hard again with this skill - not only did one of the bushings cut off the ears, but also the middle tongue broke (frayed.)! I changed the sleeve - I restored it to work, but if you start the jigsaw in the air, then the rod sausages a little, well, this tongue should have pressed the structure. However, “speed” does not affect - as soon as the blade is brought to the material, the file is pressed by itself.
If there is a desire and opportunity, it is better to buy a Makita or something else decent for a couple of thousand, and leave this guano as it is and not be fooled! When I was buying this unit, a saleswoman in a Boshevsky store told me, saying, “Skill - you need to be gentle with it, don't press hard - prices for spare parts hoo”. F))
Knowledge typical power tool malfunctions is necessary for both the home craftsman and the professional. Knowing how to correctly identify the source of the problem and quickly repair the tool saves time and money. And knowing the reasons leading to a breakdown allows you to act proactively, avoiding modes of operation in which the tool will be prematurely damaged.
The jigsaw is a versatile power tool suitable for working with a variety of materials. It can work with wood, metal, plastic, etc. This versatility is ensured by the use of a huge variety of saw blades, which are available for all occasions. During operation, the jigsaw and its components are subjected to high mechanical stress. The experience of service centers for the repair of power tools, as well as professional advice help to identify main malfunctions of jigsaws and causes their occurrence.
Support roller breakage... The saw blade, fixed in the jigsaw, is its main working element that performs useful work. The jigsaw is attached to the jigsaw support roller, and this roller bears the greatest load when cutting the material.
Reasons why the support roller can be overloaded and prematurely damaged:
using a low-quality file;
using an overly blunt file;
using a file that does not correspond to the nature of the work being performed.
As a result of overheating, the roller may simply jam. Otherwise, the roller itself may be cut with the saw blade.
Methods for preventing this breakdown
use only high-quality components;
change the canvases in time, without waiting until they become very dull;
use canvases that correspond to the nature of the work performed;
operate the jigsaw carefully, avoiding excessive cutting forces, and follow the manufacturer's recommendations.
Breakage of the blade fixation unit... Toolless saw blade retention is a convenient feature found in many jigsaw models. Allows you to quickly change the cutting tip without wasting a lot of time. The problem is that this unit can fail due to the frequent ingress of dust generated by the jigsaw during operation.
Preventive measures
periodically clean the web mount from dust;
lubricate it, if necessary, with WD-40 greases;
use the ability to connect a vacuum cleaner or dust collector to a jigsaw.
Damage to gearbox components... The reason is all the same dust that can get inside the gearbox through the ventilation holes and lead to breakdowns. As in step 2, a vacuum cleaner or dust collector can help.
Kink or bend of the support rod... Breakdown can be prevented by developing a culture of accurate power tool handling. In particular, the jigsaw must not be dropped; try to avoid collisions of the body and stem with protruding parts of the processed material.
Broken teeth on the jigsaw collet... Occurs when an attempt is made to tighten an incompletely inserted file. Here, nothing but mindfulness will help.
Premature wear of the armature worm gear jigsaw and its main helical gear. It occurs when the cutting process itself begins even before the engine reaches full speed. Warning: Do not bring the jigsaw blade close to the material to be cut until normal travel speed is reached.
