Preparing the saw chain

Preparation Zoom

One of the main advantages of the basic saw tooth chain is that it can be resharpened with a round file.

An exception to this rule are the STIHL carbide-tipped "Duro chains" which are particularly wear resistant, their extremely hard cutting edges mean they need to be resharpened with special diamond cutting wheels. Please contact your STIHL Approved Dealer for more information.

 

When should the chain be sharpened?

Even the best saw chain wears and becomes dull with time. It is time to resharpen the chain when one of the following conditions occurs:

  •  The chain does not pull itself into the cut, it has to be forced to cut by applying pressure to the powerhead.
  • When bucking, fine sawdust is pulled from the cut instead of coarse, thick chips.
  • Smoking in the cut even though chain lubrication is good and the chain tension is correct.
  • The cut wanders in one direction. This is an indication of dull cutters on one side of the chain or irregular cutter lengths.
  • The saw "chatters" and "bounces" during the cut. In this case you must check the depth gauge settings.
