Maintaining and Sharpening Saw Chain
Correctly sharpened chain
A properly sharpened chain slices through wood effortlessly and requires very little feed pressure.
Do not work with a dull or damaged chain as it will increase the physical effort required, cause higher vibrations, produce unsatisfactory results and a higher rate of wear.
:Clean the chain.
:Check the chain for cracks or damaged rivets.
:Replace any damaged or worn parts of the chain and match the new parts to the shape and size of the original parts.
It is necessary to observe the angles and dimensions specified below. If the saw chain is incorrectly sharpened – especially if the depth gauges are too low – there is an increased risk of kickback and resulting danger of injury.

The chain pitch (e.g. 3/8") is marked near the depth gauge of each cutter.
Use only special saw chain files. Other files have the wrong shape and cut.
Select file diameter according to chain pitch – see table "Sharpening Tools".
You must also observe the following angles when resharpening the chain cutters.
