Files and how to work with them
Use a special saw chain round file for sharpening. Standard
round files are unsuitable. For the order number, see "Acces-
sories".
Type 086, 484, 686: File the first cutter half with a 4,8 mm dia.
round saw-chain file, then switch to a 4.5 mm dia. file.
Type 093, 099: File the first cutter half with a 5,5 mm dia. round
saw-chain file, then switch to a 4.5 mm dia. file.
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.
New saw teeth must be filed to the exact same shape as the
Chain typ
used teeth, including on their running surfaces.

File depending on chain type (90° or 10° to the guide bar).
A file holder makes file guidance easier. It is marked for the
4/5
correct sharpening angle of:
(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 "Accesso-
ries" for the order number.
Correct even the smallest excess height with a special flat
file ( 1). See "Accessories" for the order number.
Round off the front of the depth limiter (2).
