How to check a chainsaw calm by number

Ignition check. a necessity

Many users are also interested in another question: how to check the ignition on a chainsaw. In the video, the subtleties of this process are clearly shown. First of all, the ignition coil is checked:

• visual assessment of the contamination of nodes;
• isolation of wires and their serviceability;
• reliability of contacts and the degree of strength of their fixation;
• presence of rust.

Then the spark plug cap and circuit breaker are checked. If everything is in excellent condition here, then most likely the ignition coil is working fine. However, it will not be superfluous to assess its resistance. It is extremely difficult to measure this indicator. It is necessary to know not only the resistance criteria of the windings of the part, but also many other nuances. That is why, having decided to check the magneto of the chainsaw, as the ignition coil is called, you can use the negative and high-voltage wires. However, the results are not always reliable. Sometimes the chain can ring. As practice shows, most often this indicates a complete malfunction.

The spark is checked with a special technical device. How to check the ignition coil on a chainsaw in this situation? The device is fixed in the open circuit. A section is selected between the high-voltage wire and the candles. This device can rarely be found among ordinary users. Due to its high cost, it is advisable to check the spark with its use in service centers.

Visual assessment

• correct setting of idle speed;
• the degree of chain tension;
• general adjustment.

After all, most of the models did not go through the pre-sale preparation procedure. That is why, if the buyer does not know the intricacies of using a chainsaw, it is worth contacting an expert. He will help to check not only its adjustment, but also the general operating condition. It is very important to make a visual assessment of the device. It is necessary to adjust the number of idle revolutions. You should also evaluate the chain tension. It is equally important to determine if the chain is dull. The height of revolutions deserves special attention.

External condition is an important criterion

• kinks;
• dents;
• cracks.

Particular attention should be paid to the pipes. If these parts are deformed, they should be replaced immediately. In the event that the device has been stored for a long time, it is necessary to completely drain all the available fuel. Oil and gasoline mixed with each other will form a sludge over a long period. It can ruin the carburetor condition.

How to test a chain?

When it is necessary to check the chainsaw, it is worth separately assessing the lubrication of the chain and its general condition. It should be well taut. The tire is a separate criterion. This part must be undeformed and perfectly straight. Tighten the chain if necessary. The tire sprocket is treated with oil. Provision should be made for the chain not to sag. If this problem cannot be corrected, then it is advisable to replace the part. If the chain is not tensioned to the correct level, injury to the user is very likely.

It is necessary to check the degree of sharpening of the chainsaw. Using a device with a dull circuit increases the load several times. That is why the clutch and piston elements can fail very quickly.

How to completely check a chainsaw

Fake? It is worth finding out in advance!

How to determine before buying that this is an original Stihl chainsaw? The easiest way to do this is by the serial number. You can find it right under the muffler. This is the crankcase of the device. Sometimes the manufacturer indicates this information above the bumper. It is located slightly away from the muffler. On the same part of the original product, there will be not only numerical information, but also the company logo.

Another criterion indicating that this is a real Stihl chainsaw is the presence of a branded sticker. It must be present on the case itself or under a serial designation. There is a barcode on the sticker.

The main reasons why the chainsaw is misdirected

If the chainsaw starts to cut crookedly during operation, then besides an uneven cut, we get a number of the following negative consequences:

• It is necessary for the sawyer to exert physical effort to keep the tool in a straight direction.
• Fuel consumption increases, which is associated with an increase in the trajectory of the tool passing through the material being cut
• Increased load on the drive sprocket, which leads to accelerated wear
• The tire wears out as the load only increases on one side
• Decreases tool performance
• Obtaining a cut curve. If the forest is being prepared for the manufacture of boards, then crooked trunks are equated to scrap. If the tree is cut for firewood, then as a result, the curved-sawn log will not be very convenient to chop
• Discomfort during work. the master gets tired quickly, working with a faulty tool

Why can a chainsaw cut trees crookedly? Many people might think that the reason is a malfunctioning chainsaw tire, but in fact, there are four main reasons:

• Incorrect or uneven sharpening of the teeth
• Using a chain, bar or sprocket that does not match in pitch
• Saw head wear. this is often due to abrasion on one side of the bar
• Untimely tightened chain

If such a malfunction occurs, such as uneven cutting of wood, then it is necessary to resort to its elimination as soon as possible. If you continue to operate the tool with such a malfunction, this will lead to engine wear and the need to repair it.

How To Identify Your Chainsaw Chain

Let’s consider each type of malfunction separately, and find out how to determine what is the reason why the chainsaw is sawing on its side.

If the saw head is incorrectly selected

Often, most sawers simply do not pay attention to the fact that not only the chain has technical characteristics, but also the tire and the drive sprocket with a crown. All these details must correspond to each other in such a technical parameter as a step. Most chainsaws are equipped with a headset with standard pitch parameters equal to 0.325. The tire, chain and drive sprocket, or rather the crown, must have the same pitch. If one of these parts does not meet one standard, then this will lead to accelerated wear of individual parts and the entire tool.

The tire also has such a parameter as the groove width. The value of this value can vary from 1.1 to 1.6 mm, depending on the power of the tool. It is categorically contraindicated to install a tire with a groove width of more than 1.3 mm on a household chainsaw. A standard chain in such a tire will have too much play, which will lead to accelerated wear of both parts.

Never buy an instrument headset if you don’t know or remember the exact measurements. A “like this” chain, bar or sprocket may be far from suitable for your tool, and eventually all consumables will need to be replaced. To find out the width of the tire, you will need to use a caliper or look in the technical description for the tool.

Severe saw blade wear

The tire lasts much longer than the chain. However, this does not mean that you can use it forever and not think about replacing it. Usually the guide changes after 2-3 worn chains. Before replacing the chain saw guide, you need to assess its technical condition. If a Chinese-made tire is installed on the chainsaw, then it can wear out faster than the chain. That is why, when a chainsaw is found to cut wood with a chainsaw, it is necessary to diagnose the tire.

Remove and inspect the tire to be sure it is worn out. Usually, wear is manifested by a shortened one of the sides. Sometimes it is extremely difficult to detect this visually, so you need to use a caliper. A difference of a few tenths of a mm indicates that the tire needs to be replaced. There is also an easy way to check rail wear with a square. To do this, the tire is located on a flat surface, and a square must be attached to it from the side. If the top and bottom walls of the guide are in contact with the square, then the part is in good order.

Accelerated tire wear can occur due to a malfunctioning oil pump. If the lubricant is supplied with long interruptions, then friction increases accordingly, which means that the parts wear out faster. If the lubrication mechanism works properly, then this significantly increases the service life of not only the headset, but also the entire tool.

Why is it heated

In some cases, during operation, you may notice that the tire is overheating, there are two reasons for this phenomenon. The first is a factory defect. In such parts, low-quality bearings are installed, which heat it up during operation. The defective part will warm up and nothing can be done about it, only a replacement but a new one.

The second reason is, again, not enough lubrication, or its complete absence. If such signs of overheating appear, such as the paint melting at the tip of the tire and its strong smoke, it is worth stopping the operation of the tool and contacting the service center.

The choice of a tire for a chainsaw largely depends on the characteristics of the chainsaw itself. It is worth choosing only the components recommended by the manufacturer, taking into account the pitch of the drive sprocket, the width of the groove for the chain and the shape and size of the shank. The guarantee of a long service life of the saw headset of the chainsaw is an uninterrupted supply of sufficient lubricant of the appropriate brand. Excessive bar and chain wear and heat are signs that the chain lubrication system is not working properly. We have highlighted the main points of the choice, remember them and take them into account when buying, and then you will definitely buy what you really need.

The chainsaw is a truly unique tool that makes felling and sawing wood easier. The main advantage of this tool is a quick set of maximum revolutions, as well as the ability to instantly brake the chain. During the operation of the tool, various malfunctions occur, and one of them is an uneven cut. If the chainsaw cuts crookedly, then this causes inconvenience to the sawer, and also consumes a large amount of fuel. If you are faced with such a malfunction, then in this materials you will learn how it can be determined and eliminated.

When the chain is loosened and how dangerous it is

Every chainsaw needs to be tensioned regularly. If this rule is not followed, then the consequences can be very traumatic. Most sawers know what this is about and how to tighten or tighten the chain correctly. Correct cutting attachment tension. when trying to pull it away from the tire, three shanks are fully visible, as shown in the photo below.

If the chain is slack or over-tensioned, it will wear out the bar. And not only the guide, but also the sprocket, bearing and motor. That is why make it a rule to check the chain tension before using the tool.

Which bus is better to install

It is quite simple to answer the question of which tire is better to install on a certain model of a chainsaw. It is worth installing the model recommended by the tool manufacturer. As a rule, the leading companies for the production of chainsaws, in parallel with the release of the tool itself, are engaged in the production and consumables that are specially designed for their tool.

Accordingly, the choice of a tire for a chainsaw, it is better to make in the direction of products designed specifically for your model and made by the manufacturer who assembled the saw itself.

If this is not possible, a good choice is chainsaw tires, which are made by leading chainsaw and chainsaw tire companies such as Oregon.

Tire wear. how to troubleshoot belt faults

If the guide has uneven wear on both sides, it is recommended to replace it. However, there is a way to restore a part, which requires a minimum set of necessary tools. Alignment is carried out using a grinder and a grinding disc (not cutting). First, we check the tire, and make sure that it has uneven wear. How to check the wear of the guide, already mentioned above.

Next, consider the instructions on how to eliminate uneven wear on the guide:

• Install a cleaning disc in the grinder’s spindle, and then fix the grinder in a vice
• Make a flat surface on which the guide will be located. It is recommended to use a piece of chipboard as a surface, which must be fixed with a clamp.
• Lean against a square and align the wiper blade with the surface.
• Start aligning the tire. To do this, we place it on the surface, turn on the grinders, and carry out its longitudinal movement
• When aligning the guide, it is important to keep it moving at a uniform speed. Sewing is necessary until both edges are the same size. The check must be done with a square.

over, the alignment must be done for both sides of the tire. After finishing work, you can install the headset on the tool and check. It is important to note that aligning the guide, which has uneven wear on one side, is only appropriate if the groove is deep enough to pass the chain shank. If the groove becomes shallow, then the tire must be replaced.

As you can see from the material, there are many reasons why a chainsaw cuts crooked. However, even a beginner can find this cause and eliminate it if you approach the solution of this issue appropriately. Start the check in order, as indicated in the description, and you will definitely identify the reasons that can be eliminated in different ways.

The chainsaw bar is the guiding and fixing element of the saw headset. The blade itself, the drive sprocket and the fasteners are consumables.

It is very dangerous to work with a broken tire, since at high speeds it can break off the body and damage the operator, or due to poor fixation on such a belt, the chain can come off and cause injury.

Most often, the wear of this element of the chainsaw occurs naturally, due to long-term operation. Since it bears the main load when cutting. But there are situations when the tire breaks due to improper operation of the tool. Excessive loading out of specification of the tool.

Or lack of proper maintenance of your chainsaw. In addition, there is also such that a professional or semi-professional tire is placed on a low-power unit, or vice versa, tires intended for household saws are placed on a pro tool and a station wagon.

First of all, the tires differ among themselves in length. So for household saws, 11 and 13 “tires are suitable, for universal and professional 14. 16” tires. Also, the elements vary in design features. There are flat and narrow canvases, there are two-piece canvases, interconnected by polyamide, and finally, with a removable head.

Reasons that lead away from a straight cut

Sometimes there are situations when it is almost impossible to make a straight cut with a chainsaw, the tire goes to the left or right. The reason for this behavior of the tool may be the following:

• Incorrect chain sharpening. The teeth of the chain are sharpened more on one side than on the other. You can fix the problem by sharpening the chain correctly.
• Uneven wear of the chain links, the support pads of the chain links on one side have a large output, because of which the chain tilts slightly and it is no longer possible to obtain a straight cut. The problem can only be solved by replacing the chain.
• Last but not least, uneven wear. As in the previous case, for this reason, the chain will change the slope and it will no longer cut exactly. The problem can be solved only by replacing the tire.

Chainsaw – How to Find the Model Number

The inability to make a straight cut with a tool is a sign of increased tire and chain wear, which in turn is worth looking for its cause. Eliminating the effects of wear by replacing consumables will not bring the desired result, because in case of unresolved malfunctions of the lubrication system, after a while everything will be repeated.
