Files and how to work with them
Sharpen using a special file holder with a saw chain round file dia. 5/32" (4.0 mm). Normal round files are not appropriate for this work. See "Accessories" for the order number.
The file should cut only when pushed forwards (arrow). Lift the file when leading it backwards.
First sharpen the shortest cutter. The length of this cutter is then the standerd for all other cutters of the chain.
Always guide the file horizontally (90o to the guide bar).

After having sharpened the chain, the height of the depth limiter must be checked by means of a chain gauge. See "Accessories" for the order number.
Correct even the smallest excess height (13) with a special flat file. See "Accessories" for the order number.
Round off the front of the depth limiter (14).
