Do-it-yourself Interskol saw repair

In detail: do-it-yourself interskol saw repair from a real master for the site my.housecope.com.

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 on 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:

welded;
one-piece with a removable tip;
solid with carbide tip.

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 guard 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 tear 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 at 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.

If the saw does not turn on, it is necessary to check the presence of power, the integrity of the wires and connections.
If everything is in order in the power supply, it is necessary to check the chain brake, which blocks the operation of the tool. To eliminate this problem, you must move the brake shield to a different position.
If the measures described above did not turn on the saw, then it is necessary to check the integrity of the cable and plug.
If the saw power has decreased, productivity has dropped, it is necessary to replace the carbon brushes, which, apparently, are worn out.
Quite often, the chain does not start to stop immediately, but after a certain period of time. The longer the saw is used, the longer this time interval becomes. To get rid of this problem, it is necessary to replace the saw brake band, which has worn out over time.
The saw often produces an unpleasant, cutting sound in the ear. This sound often appears due to a lack of oil in the mechanism or due to contamination of its conductive grooves. Troubleshooting is simple - add oil and clean the furrows.
It is important to use only original spare parts recommended by the manufacturer for repairs. Using third-party spare parts often leads to tool breakage or hazardous situations.
If there is damage to the case, then for your own safety, the saw must be returned for repair.
Do not replace cutting parts of the tool that are not recommended by the manufacturer or do not fit in design.

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:

before starting work, make sure that there are no solid metal objects in the workpiece. If contact of the cutting element with a metal object occurs, then a notch or chip will remain on the chain, which can no longer be removed;

it is impossible to carry out work on the ground, as the deepening into the ground will clog the oil grooves, as a result of which the chain will remain without normal lubrication and will wear out faster;
it is necessary to monitor the saw wedge, it must not be allowed, as this overheats the metal and reduces its service life.

2. How to determine if the saw needs sharpening. To do this, it is enough to pay attention to the chips - 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.

3. How to sharpen an electric saw yourself:

a special tool is required for sharpening, this is a set of round and oval files, a mandrel and a caliber;
sometimes the kit additionally includes a hook for cleaning the chain slots from chips;
a round file is combined with a mandrel;
flat file and caliber are used separately;
the chain is sharpened on the saw blade itself;

for sharpening on the machine, the chain is removed from the bar;
the chain is installed on the guide of the machine and tightened with a roller and a ratchet, which hold it by the cutting tooth;
the machine has a protractor that sets the sharpening angle;
the abrasive wheel is lowered, with its help an insignificant layer of metal is removed - about a few tenths of a millimeter. This is the process of straightening and sharpening the chain;
after straightening one tooth, the guide is rearranged to the next, and so on;
this type of sharpening allows you to withstand the rigid framework of dressing and sharpening the tool;
if there is a desire to purchase such a machine for yourself, then it is recommended to purchase not an electric version of it, but a manual one, since its cost is much lower. The machine allows you to push back the repair of Bosch electric saws and any other manufacturers.

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 it is necessary to sharpen the saw. 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 the electric saw chain.

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 one 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.

Is your TV, radio, mobile phone or kettle broken? And you want to create a new topic about this in this forum?

First of all, think about this: imagine that your father / son / brother has an appendicitis pain and you know from the symptoms that it is just appendicitis, but there is no experience of cutting it out, as well as the tool. And you turn on your computer, access the Internet on a medical site with the question: "Help to cut out appendicitis." Do you understand the absurdity of the whole situation? Even if they answer you, it is worth considering factors such as the patient's diabetes, allergies to anesthesia and other medical nuances. I think no one does this in real life and will risk trusting the life of their loved ones with advice from the Internet.

The same is in the repair of radio equipment, although of course these are all the material benefits of modern civilization and in case of unsuccessful repairs, you can always buy a new LCD TV, cell phone, iPAD or computer. And for the repair of such equipment, at least it is necessary to have the appropriate measuring (oscilloscope, multimeter, generator, etc.) and soldering equipment (hairdryer, SMD-hot tweezers, etc.), a schematic diagram, not to mention the necessary knowledge and repair experience.

Let's consider the situation if you are a beginner / advanced radio amateur who solders all sorts of electronic gizmos and has some of the necessary tools. You create an appropriate thread on the repair forum with a short description of “patient symptoms”, ie. for example “Samsung LE40R81B TV does not turn on”. So what? Yes, there can be a lot of reasons for not switching on - from malfunctions in the power system, problems with the processor or flashing firmware in the EEPROM memory.
More advanced users can find the blackened element on the board and attach a photo to the post. However, keep in mind that you replace this radio element with the same one - it is not a fact that your equipment will work. As a rule, something caused the combustion of this element and it could “pull” a couple of other elements along with it, not to mention the fact that it is quite difficult for a non-professional to find a burned-out m / s. Plus, in modern equipment, SMD radio elements are almost universally used, soldering which with an ESPN-40 soldering iron or a Chinese 60-Watt soldering iron you risk overheating the board, peeling tracks, etc. The subsequent restoration of which will be very, very problematic.

The purpose of this post is not any PR of repair shops, but I want to convey to you that sometimes self-repair can be more expensive than taking it to a professional workshop. Although, of course, this is your money and what is better or more risky is up to you.

If you nevertheless decide that you are able to independently repair the radio equipment, then when creating a post, be sure to indicate the full name of the device, modification, year of manufacture, country of origin and other detailed information. If there is a diagram, then attach it to the post or give a link to the source. Write down how long the symptoms have been manifesting, whether there were surges in the supply voltage network, whether there was a repair before that, what was done, what was checked, voltage measurements, oscillograms, etc. From a photo of a motherboard, as a rule, there is little sense, from a photo of a motherboard taken on a mobile phone there is no sense at all.Telepaths live in other forums.
Before creating a post, be sure to use the search on the forum and on the Internet. Read the relevant topics in the subsections, perhaps your problem is typical and has already been discussed. Be sure to read the article Repair strategy

The format of your post should be as follows:

Topics with the title “Help fix the Sony TV” with the content “broken” and a couple of blurred photos of the unscrewed back cover, taken with the 7th iPhone, at night, with a resolution of 8000x6000 pixels are immediately deleted. The more information about the breakdown you put in a post, the more chances you will get a competent answer. Understand that the forum is a system of gratuitous mutual assistance in solving problems and if you are dismissive of writing your post and do not follow the above tips, then the answers to it will be appropriate, if anyone wants to answer at all. Also note that no one should answer instantly or within a day, say, no need to write after 2 hours “That no one can help”, etc. In this case, the topic will be deleted immediately.
You should make every effort to find a breakdown on your own before you get stuck and decide to go to the forum. If you outline the whole process of finding a breakdown in your topic, then the chance of getting help from a highly qualified specialist will be very great.

If you decide to take your broken equipment to the nearest workshop, but do not know where, then perhaps our online cartographic service will help you: workshops on the map (on the left, press all buttons except “Workshops”). You can leave and view user reviews for workshops.
