How to Properly Install a Chain on an Electric Saw
It is a common practice to change a saw chain when it is completely worn out and sharpening or repairing it is useless.
Going to the store for a new component, you need to arm yourself with the following recommendations:
- When changing any part of an electric saw, it is desirable to buy a product of the same manufacturer as the tool itself. That ensures the best possible results.
- It is important to consider the type of tasks to be performed. Chains with a pitch of 3/8 inch are designed for heavy loads. If the saw is rarely used, 0.325 inch will be enough.
- Tooth rake angle is important: cutting big volumes of dry wood is best done with cutting edges that have a sharpening angle of 30 degrees. For wet or frozen material, a sharpening of 10 degrees is more appropriate. The same applies to longitudinal sawing. a small sharpening angle in such cases significantly reduces the degree of wear on the cutting attachment.
- When selecting the length of the chain, you should be guided by the size of the bar.

The chainsaw chain, together with the guide bar, is the part that is most stressed during cutting, unlike other chain saw parts. Over time, it lengthens in size due to the boring of the gaps in the connecting links. This process happens to all types of chainsaws, so you should periodically monitor the chain for proper tensioning and wear when operating a chainsaw.
If the chain is too tight, the cutting performance is reduced, the motor and transmission are exposed to increased loads. The guide bar gets very hot due to increased friction, the chainsaw mode of operation goes into overconsumption of fuel mixture.

The process of pulling the track on electric saws
Any chain on the appliance must necessarily be controlled. Tensioning is quite easy:
- Examining the Fuel Crane. The system must be locked.
- Removing the candle wires or opening the decompression bolt.
- The fork of the saw is unplugged.
- The row is turned according to its movement.
The bottom of the track is slack, so you can tell when the track is not properly tensioned. There should be a constant reserve at the top that occurs when the chainstay is tensioned. Tensioning too much causes the track to stop moving.
The chain must not be adjusted if it is in working order.
For convenience and safety of storage, electric saws are equipped with special covers.
