Why does the chain on the electric saw fly off? Do-it-yourself electric saw repair - Setafi

Sometimes the chain from the saw can fly off right during operation. This is due to insufficient tension and lack of periodic checks. Repair of the chain saw is carried out independently, for this a few minutes are enough. After restoration, you need to check the tension - normally, the move should be smooth, while the chain should not sag. How to do this is described in the article.

Main reasons

To carry out a competent repair of an electric saw, you first need to figure out why the chain flies off it. The main reasons are:

• tire failure (often deformation);
• heavily worn groove;
• a malfunction on the side of the chain (the internal teeth that slide along the groove have broken off).

First you need to make sure that the chain tension is normal. To do this, they act like this:

1. Pull with fingers on either side.
2. Examine the internal teeth.
3. They should slide normally along the groove and not completely come out of it.
4. Manually pull the chain over the bar. If the move is smooth, there is no sagging, then everything is in order. This is how the repair of the Makita electric saw and other models begins.

5. If the chain is too tight, there is a need for a little loosening, otherwise it may break during sawing.

The main reason why the chain on the saw flies is due to weak tension. This is noticeable by how much it sags. Moreover, if only 1-2 teeth (no more) fall out of the groove completely, this is an acceptable situation. But if 3 or more - you need to make a tension (but not too tight).

How to repair

If the cause is due to a weak tension, it is necessary to tighten the chain a little. And it does not matter which circuit is on yt4334 01 or other models. Their device and principle of operation are the same. To troubleshoot the problem, proceed as follows:

1. Loosen the nut that secures the tire.
2. Using a screwdriver, turn the adjusting screw next to the tire.
3. Then tighten the nut.
4. Check the move - it should be smooth, not too tight, but without sagging.
5. If necessary, adjust and check again.

There is also such a problem in which the chain on the saw is not lubricated. The main reasons are associated with a clogged oil filter, tube, or a malfunction on the part of the oil pump. In these cases, it works like this:

1. Remove the protective cover.
2. Remove the tire, chain.
3. Clean all openings through which oil is supplied.
4. Then you need to understand how to assemble an electric saw. To do this, perform the same steps, but in reverse order.

It is not recommended to start work immediately. First, it is better to make sure that the oil is no longer leaking, since it should only come out during operation. To do this, put a sheet of paper on the table and turn on the lamp. Then connect the saw to the outlet and run over this sheet. If oil drops appear on it, then the problem is solved.

Fault Prevention

Repair of electric saws can be done at home. But to avoid problems, it is recommended to follow the standard preventive measures:

1. Regularly clean and lubricate the filter using industrial oil.
2. If necessary, it is better to replace the filter so that the saw works properly.
3. Before starting work, check the bolts and nuts - they must be tightened tightly enough.
4. Lubricate bearings and sprocket regularly.
5. Sharpen the chain promptly. You can do this yourself with a file or turn to a master who works with a professional tool.

Thus, the chain almost always flies due to low tension. You can fix the problem yourself. At the same time, do not pull it too tight - otherwise the chain may break.
