Preparing to Sharpen a Chainsaw
When do you need to sharpen your chainsaw?
Even the best saw chain wears and becomes dull after a certain period of use. 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 in order and 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.
Preparing the saw chain
Start by cleaning the saw chain thoroughly, e.g. with STIHL resin solvent. You should examine the chain for signs of damage at the same time. Replace any damaged or worn parts immediately.
If the wear marks have been reached, install a new chain.
In such a case you should contact your STIHL servicing dealer for advice.
