How to tension the chain on the Forrest chain saw

When to change the chain

The need to replace the chain mainly arises when the chain is worn and overstretched. If you can’t tighten the tool with the adjusting screw, you need to replace it. But installing a new part on an old, worn sprocket and the same bar is not recommended, because it will wear out quickly.

Many owners of electric saws know that the chain wears down 2-3 times faster than the bar and sprocket wear out, and resort to a little trick.

  • When you have a new chain saw you should buy 3 saw chains at a time.
  • After one chain has been in use for a few hours, it must be replaced with a new one. Next, the second chain is changed in the same way.
  • After each change, you need to turn the bar for even wear.

Carrying out these simple manipulations leads to even wear of all parts and prolongs their service life.

Sawing problems and solutions to these problems

Sometimes the operator encounters some difficulties while working with an electric saw.

How to adjust the chain correctly?

You can install the chain and adjust the tension with your own hands without having to go to a service center, regardless of the class of chainsaw, its age. Each link should be fully checked before beginning work, since slack can also be caused by worn teeth or sprockets. STIHL 180, Husqvarna, Champion, Partner and other models:

  • Position the tool on the table with its headset on top. unscrew the threaded fasteners of the protective cover, remove the bar and thoroughly clean each element (it is convenient to use a vacuum cleaner or a cylinder with compressed air);
  • determine the correct chain position. The teeth should be on top, running in the opposite direction to the body;
  • Pull it straight onto the bar. Check the bolt mechanism, make sure there is enough clearance.

To check tightness

To check tension it is sufficient to pull the chain off the middle of the bar, no more than 2/3 of the chain link shanks may protrude.

  • The chain must not be blocked when manually sliding it over the bar if it is properly adjusted.
  • Also eliminates squeaking and other extraneous noises around the drive sprocket location.
  • After running the chain, you need to check the tightness of the tire thread fasteners and the protective cap.

The chain does not tighten after a long period of use, because of a lack of adjustment travel in the tensioning mechanism. The chain is designed so that it can be sharpened by removing a few links. On the other hand, such economy turns out to be a loss of chain smoothness and accelerated wear of the bar and drive sprocket rim.

Necessary gadgets and tools for tightening the chain on the chainsaw

In order to tension it correctly, you need some simple know-how and a few simple tools. On STIHL chain saws, tensioning is easy with the integrated chain tensioner. This method is as simple as possible and is very quick to tighten. To tension or adjust the amount of slack in the chain, the manufacturer recommends you do this:

  • unscrew the sprocket cover with a wing nut;
  • Turning the adjusting wheel determines the required chain length, tightening it to the required degree;
  • close the sprocket cover again and the chain is secured to the bar.

If you can not tighten the chain of a chainsaw built-in mechanism, use these tools (by the example of an electric saw Sparky):

  • angle grinder with a metal disk;
  • Allen wrench, 5 mm in diameter;
  • A piece of wire;
  • a wooden stick or a sturdy chip;
  • flat screwdriver.

After de-energizing the electric saw, unscrew the screws with an Allen key, remove the housing cover, unscrew the tensioning screw with a screwdriver and remove the stem nut. The side of the screw adjacent to the saw body is ground with a disk. Then the saw is assembled in the reverse order. The sawdust is needed to clean the body from sawdust.
