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 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.
