Chainsaw modifications are usually thought of when something is missing. For example, a milling machine. This will require:
The procedure is as follows. The wheel is welded at the end of the boom base, cutting off the boom so that the wheel exactly enters the cut contour to prevent tension or loosening of the chain. A removable adapter for cutters is attached to the wheel.
We hope that after reading the information briefly presented in our article, you will be able to independently eliminate minor faults that have arisen and operate this tool as a confident user.
Electric saws are an indispensable tool in a summer cottage or in a private house. It easily copes with cutting thick branches, planks and various wood materials. Even the most reliable tool has its own degree of wear, it is periodically required to correct minor or major breakdowns. Do-it-yourself electric saw repair is possible only in some cases and in the presence of certain skills and tools. Often the tool has to be returned to the service. But there are some breakdowns that can be easily corrected on their own.
In order to master the skills of repairing electric saws, it is necessary to understand their design. The main element that cuts the material is the saw chain, which is driven by the motor. The chain itself is a set of cutting links, which are held together by hinges. The movement of the chain is carried out along a plate, which is called a tire. This part is made of high quality steel, which is not subject to chips, scratches and corrosion - this is the main indicator of the quality of the tool. Tires are distinguished by design:
A welded bar is something like a "sandwich" that is welded from three parts into one, with a driven sprocket riveted into the structure. One-piece design with replaceable tip - one sheet product, ideal for long instruments. In such a tire, the main load falls on the roller bearing of the driven sprocket. One-piece configuration can reduce friction loss by 8-10%. If the tool has a solid carbide tire, then it is optimally suited for work with high loads, as well as for use in conditions where there is a lot of sand, dust and dirt.
1. When working with an electric saw of any configuration, it is necessary to remember about the possibility of a "kickback" - throwing the tool towards the person performing the work. This situation occurs when the very end of the guide bar rests against the material being cut. To avoid injury in such a situation, manufacturers equip saws with an automatic chain brake.
2.An automatic chain brake is also called an inertial drive, which works thanks to a shield located in front of the left hand of the person performing the work. Before starting work, this shield is placed in a position closer to the hand so that it can be quickly activated if necessary. If there is a moment of kickback, then the operator's hand rests on this guard and the chain stops. The position also changes due to the inertia arising from the impact. Such a system makes it possible to reduce the likelihood of repairing electric chain saws, since its main mechanism will not be damaged during an impact.
3. Another system that prevents wear and damage is automatic chain lubrication. Oil is poured into a special reservoir, which, during the operation of the saw, is transferred through the oil pump to the drive sprocket and chain. Some models even have an oil supply regulator, since different amounts of oil are needed for different intensities of work. For example, repairing a Makita electric saw involves inspecting the oil supply system.
4. Electric chain saws have some drawbacks or weak points. One of them is the gearbox design. The torque is transmitted to the chain through a gearbox, which is rigidly connected to the anchor of the electric motor. This design transfers all the loads to the motor, that is, if the workpiece contains solid inserts or the saw chain is dull, then it will not slide so smoothly over the surface. This will result in overheating of the motor or wear of some of its parts. As a preventive measure, it is necessary to sharpen the saw in a timely manner and not to put pressure on it while working. Often they come to the service repair of a Parma electric saw with this kind of malfunction.
5. The second weak point of saws with an electric motor is the dependence on the voltage in the network. If it falls, the load on the motor increases, in models that are not equipped with thermal protection of the motor, the increasing load leads to its combustion. But the temperature rise protection also has disadvantages, since at low voltage it is triggered, reducing performance. For example, the repair of an Interskol electric saw is often reduced only to an increase in the voltage in the network, after which the tool functions properly.
One of the saw elements that you need to keep track of yourself is the chain.It must be sharpened prophylactically, since if it is delayed with this process, it will no longer be possible to repair the electric chain saw with your own hands. It must be taken to a service where they will be sharpened on professional machines.
1. Extending the service life of the saw blade:
2. How to determine if the saw needs sharpening. To do this, it is enough to pay attention to the shavings - if they are small and slightly darker, then the chain is dull. This is because the blunt edges do not remove the required cutting layer, which leads to chip breakage. Also, the quality of saw sharpening is determined on the basis of visual inspection, there should be no radii on the saw part, no damage in the form of torn sections, the shape of the tooth and cutting edge should be the same as on a new tool.
If all these factors do not meet the necessary requirements, then the saw needs to be sharpened. Continuing to work on a blunt saw will have an impact on productivity as well as the service life of the saw. With sharpened elements, the load on the motor increases, it overheats and all its elements wear out faster than the specified period.

The INTERSKOL PC-16 2000T chain saw is equipped with a powerful 2-kilowatt motor. The Oregon bar measures forty cm (16 inches). This length is enough to cut down small trees, collect firewood, and carry out construction work. The saw allows you to cut wood not across, not along the grain. The spike retains the oil-like grip better on the workpiece and reduces operator stress. Saw weight (fully equipped) - 6 kg.
Protection against accidental activation increases the safety of work.
For trouble-free operation, the chain is automatically lubricated with a plunger pump.
The inertial brake stops the chain in case of emergency (nettles, kickback).
The volume of the oil tank is eighty-five milliliters.
Due to the affordable price, you can buy the INTERSKOL PTs-16 / 2000T electric chain saw for use in the country or in a suburban area. In the online store "220 Volt" you will always find a suitable delivery option without paying for the order.
What remains for our client to do is that chain saws are suitable for sawing wood not in the transverse, not in the longitudinal directions, and the PC-16 / 2000T is no exception.
This common hearing tool is equipped with a powerful motor, gearbox and Oregon chain saw. The chain is lubricated by a plunger pump located in the gearbox housing.
The saw has a number of safety non-blocking devices. Electric saw repair. DIY electric saw repair, short video about. The main thing is that the power-on lock button does not allow accidental pressing of the start key. On the additional handle there is an additional switch that blocks the engine. Thus, the engine can only be started by grasping both handles.
Additional safety device installed on the instrument. the inertial brake lever, which is responsible for emergency braking of the saw chain, for which the saw's rebound design is intended (this happens with careless work).

The Russian company "Interskol" was founded in one thousand nine hundred and ninety-one, its main office is located in Khimki, Moscow region. Do-it-yourself electric saw repair video all user video: vyacheslav viter. The products of this company are power tools of various classifications (drills, saws, hammer drills, grinders), its products are distributed in numerous CIS countries, in some regions of Europe and the Middle East.
According to the research carried out, Interskol is the most popular domestic company in our country. And when in two thousand and nine, oil-like acquired the Italian company Felisatti - the tools became more versatile.
One of the advantages of this company is that, like oil, it produces quite diverse products, without buying an expensive unit yet, they buy some small one to do, as it is also called a tool, in order to check the quality of manufacture, not visually make sure of the reliability of this manufacturer.
In the current situation, the products of this Russian brand mean more than eighty types of power tools of various classes of non-functional. Not the main share of this assortment is made up of hand-held power saws. Do-it-yourself repair of Husqvarna and Calm chainsaws: video. Adjusting the carburetor, you can repair the calm 365 chainsaw with your own hands - video. About one of them, speaking specifically about the Interskol PC-16 / 2000T model, we will not talk about the review here.
Among the main advantages of this electric chain saw should be noted the already familiar lightness, convenience and low speed of work. As well as models of other brands, this tool is capable of cutting both longitudinally and not in transverse mode. Among its advantages, it is also worth noting a powerful motor, a reducer, and a reliable tire with an Oregon chain. The chain is lubricated when using a plunger pump, which is usually not a problem. They were voiced in his review by Stas Shutov from Yaroslavl:
Completely, saws well, used it for one year, then the oil pump broke down. I had to contact the service not to pay money not so much for a new pump, but at the same time for services for its replacement. A year later, history repeated itself. As a result, for repair gave almost as much as the saw itself cost.
Not although, a very significant drawback regarding the fact that it is essentially impossible to get spare parts for this saw. Considering that the chain is not a tire, grind down quickly enough -> the myth of the nuance has a very negative effect on the full operation of the saw. Therefore, our assessment for quality will be average - only seven points.

Detailed disassembly not chain assembly electric saws Dnepromash is not similar with a description of the features. How to check.
One of the main characteristics of the convenience of the Interskol PTs-16 / 2000T hand-held electric chain saw is the safety device in the guise of the engine blocking button, not the brake lever. This oil is ideal for summer cottages, but in more industrial areas it is better to choose a saw with a higher power. Do-it-yourself chainsaw repair (repair of a Chinese chainsaw). The chain enters the wood very gently so that it does not get stuck in the wood like oil, it must be sharpened regularly. The saw cut turns out to be very neat and uneven. A large, uncomfortable handle allows you to work with the saw for a long period, without a forced break.
The amount of oil is controlled using an external level, which is also very useful, but this function allows you to protect the saw from idle operation and, as a result, from overheating. Do-it-yourself chainsaw repair (repair. True, as with many similar saws, the oil runs out quickly enough, you do not have to constantly interrupt work to refuel the saw. In addition, the volume of the tank itself is small, which also causes certain inconveniences with the use of this tool.
If the oil level is not monitored, the pump can quickly break down. This, for a reason with such a feature, of course, there are some inconveniences when cutting, so the score for such a criterion is only six points.
The Interskol PC-16 / 2000T model also has problems with functionality. A thick tree cuts with difficulty, the chain can periodically jam. If you need this common rumor tool to quickly cut wood for a fire, as it is also called a fireplace, the saw will cope with this task very quickly. The review by Vadim Krupyshin from Moscow provides more detailed information:
Due to the great busyness last summer, my summer cottage was heavily overgrown. I tried to start sawing by hand, after half an hour I was exhausted and did not decide that I had to take an electric saw. I decided to stop my choice on Interskol, to be honest, I was attracted by its low cost, I didn't really think about quality in those days. And in addition, I already had the tools of this brand, but I did not fully trust him. DIY repair of chainsaws and chain saws. I bought a saw, came to the dacha, poured oil, now in twenty minutes all the work was done! True, several times there were problems with the clamping of the tire, due to the fact that he began to saw at the wrong angle. For a couple of seconds, I pulled up the chain and did not continue to work. Not a bad saw for a quite adequate price.
An additional recommendation from the owners of this tool is that it is advisable to fill in the oil with a more liquid one, so that the chain is fully lubricated. We will not give the maximum rating for functionality here, but oil has earned a solid eight points.
Most recently, the cost of this saw was very attractive - only three thousand rubles. Alas, for some reason, the manufacturer decided to raise the price by almost half now the tool costs almost as much as the best Makita electric chain saw.
Not such a change in pricing policy will have a positive effect on the popularity of the product, because the choice here will be obvious. Although a couple of years ago, probably the users between Makita not Interskol chose the products of the second brand precisely because of its low cost, they were not satisfied with such a choice, because they managed to save significant funds.
Today this model costs 6-7 thousand rubles, and for such a price you will find a better quality, unreliable electric saw. Therefore, the score for this item will be the lowest - only four points, since such a price is absolutely unjustified.

Do-it-yourself electric saw repair is of interest to all owners of such tools. It should be understood that any device has its own degree of wear, therefore from time to time it will be necessary to repair various malfunctions.
Electric saws are widely used in suburban areas for cutting branches, boards and trees.
Electric saws are indispensable tools for summer cottages or private homes. They are able to easily cope with sawing branches, thick boards, as well as various wood blanks. To repair this device, you need to have some skills and tools. In most cases, electric saws are repaired by experienced professionals. However, there are some types of faults that you can easily rectify yourself.
Elements that will be necessary in order to repair an electric saw with your own hands:
original accessories recommended by the manufacturer;
files in the form of circles and ovals;
mandrel;
caliber;
chain sharpening device.
The following breakdowns are most common:
If the tool does not turn on, you will need to check the power supply, the condition of the cables and connections.
If the supply network is in good condition, it will be necessary to check the chain brake, which stops the operation of the device. To fix this problem, you need to change the position of the brake element shield.
If the power saw fails to turn on, then you will need to check the condition of the cable.
If the power of the saw has decreased, this means that the brushes are worn out. In this case, they must be replaced.
Quite often, the chain does not stop immediately, but after a while. The longer the file is used, the longer this period of time becomes. To fix this problem, you need to replace the saw brake band.
In some cases, there is an unpleasant sound during the operation of the saw. It most often appears due to insufficient amount of oil in the device or due to clogged grooves that pass it. To rule out a malfunction, you will need to add oil and clean the grooves.
When carrying out repair work, only original accessories recommended by the manufacturer must be used. If elements from third-party manufacturers are used, then this will lead to breakdowns of the device or the occurrence of unforeseen situations.
If the case is damaged, it is best to return the tool for repair.
It is not allowed to replace the cutting elements of the device that are not intended for it.
One of the components of a saw that you need to keep an eye on is the chain. It needs to be sharpened from time to time. If you tighten up with this process, then you will not be able to repair the electric chain saw yourself. In this case, it will have to be sent to a service where sharpening will be carried out on special devices.
Saw chain lubrication system.
You can extend the service life of the sawing element as follows:
Before starting work, you need to make sure that there are no solid metal elements in the workpiece. If the element for cutting comes into contact with the metal workpiece, then notches or chips will appear on the chain, which cannot be removed in the future.
Do not sharpen on the ground, as digging into the ground can clog the oil grooves. As a result, the chain will not be lubricated and will wear out quickly.
Be sure to keep an eye on the saw blade. Jamming should not be allowed, as as a result, the metal will overheat and reduce its service life.
It should be determined whether the saw needs to be sharpened. To do this, you need to pay attention to the chips: if they are small or have a dark color, then the chain is dull. Blunt edges are not able to remove the desired cutting layer; as a result, the chips are crushed. The quality of the sharpening of the tool can also be determined by inspection. The part that is used for sawing must be free of defects in the form of torn pieces. The shape of the serration and cutting edge must be the same as when not in use.
If these factors do not meet the relevant requirements, then the saw must be sharpened.
If you perform work using a blunt file, this can affect productivity, as well as the period of possible use of the tool.

In the case of using blunt elements, the load on the electric motor will increase, as a result, it will overheat and all its parts will wear out before the specified period.
You can sharpen an electric saw as follows:
Scheme of manual sharpening of a chain of an electric saw.
To sharpen, you will need to prepare a special set of tools, which consists of files in the form of circles and ovals, a mandrel and a gauge. In rare cases, such a set may include a hook for cleaning the chain slits.
The file in the shape of a circle must be combined with a mandrel.
The flat file and the gauge must be used separately.
The chain is sharpened on the saw blade.
The mandrel is placed on the edge of the cutting teeth, and the angle of sharpening of the chamfer must be taken into account.
The sharpening angle should be between 30 ° and 100 °. The most time consuming dressing process is setting the correct angle. If you set the wrong angle, the tool will deteriorate.
The file during the sharpening process must be installed perpendicular to the shank, it should protrude slightly above the tooth.
Sharpening must be done in one direction.
When one tooth is sharpened, the chain needs to be scrolled and start sharpening the other tooth.
When all the teeth are sharpened with a file, you need to start processing the cut - a protrusion on the chain that has no edges for cutting. This element is placed on the same plate with a tooth. This device is designed to form a depression during the cutting process.
If the cut stops protrude, the chain will not cut. In this case, it will slip. If the restraining elements are deeply recessed, then the wood will jam the cutting element of the device.
Editing of the cut stops is done using a gauge. It will need to be applied to the edge of the cutting teeth. The end rail must be flush with the boundary piece.
If the limiting element protrudes, then it must be trimmed. In this case, you can use an ordinary flat file.
With a similar tool, you need to move along the bounding element in the same direction.
In this case, you need to do the following:
Angle table for sharpening the chain on the machine.
The first step is to remove the chain from the shank.
The chain is installed on the guide element of the device and tightened with a roller and a ratchet. These elements will hold the chain by the cutting teeth.
You can set the sharpening angle with a protractor, which is installed on the device.
The abrasive wheel must be lowered, with its help a small part of the metal is removed - approximately 0.001 m. Thus, the chain is straightened and sharpened.
After straightening the first tooth, the guide element will need to be rearranged to the next one. Thus, all the teeth are straightened.
With the help of such a sharpening, it will be possible to withstand the rigid framework of the fixture editing.
If you plan to buy such a device for personal use, then it is recommended to purchase not an electrical device, but a manual one. The latter is much cheaper.

It is quite simple to repair and sharpen an electric saw with your own hands, you just need to prepare all the necessary tools and follow the correct sequence of actions.
The electric saw is preferred for one good reason - it is very lightweight, and therefore easy to use. Of course, you can't go far into the forest with her - the network cable won't let you. But in use near the house (for sawing logs, preparing firewood, trimming trees, during construction and repairs), there is no better tool.
During operation, especially with frequent use, the electric saw starts to junk: it emits incomprehensible sounds, smells, does not slow down on time or does not turn on at all. There is nothing to be done - any technical device does not last forever. And every working day shortens his life. But there are breakdowns that only a professional service can handle (for example, a damaged case). And there are cases when you can reanimate an electric saw with your own hands, with effort, knowledge and skill.
We have made a selection of practical tips on how to repair a saw yourself, without going to a specialist.
Any breakdown does not occur from scratch. It is often rooted in poor build and quality, or mishandling. If you buy a quality tool from a reliable manufacturer, it is not so easy to "ditch" it. But still, most often malfunctions arise due to:
Power surges. If the instrument has built-in fuses - protection against voltage surges, then it will withstand deviations from 220 V by 10% in one direction and the other. Not more. If there is no protection, the motor will burn out.
Non-compliance with recommendations. Often the instructions say: half an hour of work, 15 minutes off. Once it is written, then it must be observed. Avoiding the mode means overheating the motor.
Untimely lubrication. In the overwhelming majority of electric saws, lubrication is automatic. Make sure not to run out of oil. Remember that running dry is death for the motor. If the oil does not automatically flow to the "asterisk", then lubricate it yourself, every 3-5 hours of operation.
Overload capacity. If it happened, this is also your fault, not the manufacturer's. If it is indicated that it is possible to cut logs up to 5 cm in diameter, then cutting a ten-centimeter trunk is clearly too much.
Design flaws. This is already an oversight of the manufacturer. The most common disadvantage is the rigid coupling of the gearbox with the armature. When transferring a strong load (blunt tape or hard wood), it wedges and heats up. Gears wear out quickly. The way out of the situation is to sharpen on time and avoid overloading.
1. Original factory parts from the same manufacturer.
It's hard to believe, but almost half of the breakdowns are due to a dull chain. It brings with it an increase in the load on the motor, its overheating and premature wear. When the sawing band is stupid, the gears of the reducer, the drive sprocket, bearings, etc. break.
Sharpening must not be carried out directly on the ground, as dirt can clog the oil grooves.
Sharpening devices are used: files (circle and oval), mandrel and caliber.
The sharpening angle must be greater than 30 degrees.
The file should protrude slightly above the tooth.
Sharpen the teeth one at a time, scrolling the tape.
After sharpening the teeth, using a gauge, you should straighten the cuts (protrusions that are responsible for the deepening during the sawing process).
If the cuts protrude slightly beyond the line of the teeth, then they can simply be cut with a file.
As you can see, troubleshooting is easy, and there is also difficult. Remember that with proper use and maintenance, the need for repairs will arise much less frequently.
In the household, especially in a private house or in the country, a tool such as a saw is simply necessary. To work with the old "friendship - 2" you need an assistant. It will be difficult for even strong men to cut several storage meters of firewood by hand and take a lot of time.
Follow the advice of experienced owners of such a tool - do not buy cheap electric saws from dubious manufacturers. In the best case, such a tool will last one or two seasons, and the cost of repairs will be comparable to the price of a new tool.
However, even the most reliable and high-quality tool can fail for various reasons. An electric saw is not a reliable and reliable Kalashnikov assault rifle. In a power tool, there are many components and parts that are subject to a certain load during operation. Problems can arise from time to time. If you do not have the skills to repair electrical units or if the breakdown is quite serious, you should contact the service center. Do you know that when buying a tool, you should pay attention to the warranty documents. During the validity of the warranty period, in case of any, even minor malfunction, in no case open the case of the electric saw. Warranty repair of electric saws should be carried out only in a workshop from the selling company.
After the warranty period has expired, minor repairs to the power tool can be performed by yourself. This requires knowledge in mechanics and electrical engineering. Some tools and fixtures will be needed.
In order to properly maintain, carry out adjustment and repair work, it is important to know its structure and the principle of operation and operation of protective devices.
The main cutting element is the saw chain, which is driven by an electric motor. The chain consists of a series of individual links with cutting teeth. The chain links are pivotally connected. The saw chain is fixed with a certain tension on the plate (bar). By design, tires can be welded, one-piece with a replaceable tip and with a tip made of refractory metal. The latter are of the highest quality and can withstand heavy loads.
In case of refusal, check:
If the instrument does not turn on. Check the voltage in the network, the integrity of the cable and connections.
Check the saw chain locking brake. The kickback protection system may have been activated. Move the brake flap to the working position.
If the saw does not produce rated power and is jerky and the motor manifold sparks, check the condition of the carbon brushes. They should be replaced.
If the usual sound of the saw operation has changed, it began to "cut the ear", check the presence of oil in the barrel. Important
The saw chain has to be sharpened periodically. If you have a special tool, you can sharpen the teeth yourself. However, it is better to have several spare chains, and trust a master to sharpen them. This will guarantee the efficient operation of the saw.
