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 (90
The file holder makes file guidance easier. It is marked for
the correct 30° sharpening angle (keep the marks parallel with
the chain when filing, see illustration) and limits the cut depth
to the correct 4/5 of the file diameter. See "Accessories" for the
order number.
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).
