Files and how to work with them
Use a special saw chain round
Þ
le for sharpening. Standard round
Þ
les are unsuitable. For the order number, see “Accessories”.
Type 086, 484, 686
: File the
Þ
rst cutter half with a 4,8 mm dia.
round saw-chain
Þ
le, then switch to a 4.5 mm dia.
Þ
le.
Type 093, 099
: File the
Þ
rst cutter half with a 5,5 mm dia. round
saw-chain
Þ
le, then switch to a 4.8 mm dia.
Þ
le.
The
Þ
le should cut only when pushed forwards (arrow). Lift the
Þ
le 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
Þ
led to the exact same shape as the
used teeth, including on their running surfaces.
File depending on chain type (90° or 10° to the guide bar).
A
Þ
le holder makes
Þ
le guidance easier. It is marked for the
correct sharpening angle of:
α
= 25°
α
= 30°
α
= 35°
(keep the marks parallel with the chain when
Þ
ling, see illustration)
and limits the cut depth to the correct 4/5 of the
Þ
le 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 with a special
ß
at
Þ
le (
1
). See „Accessories“ for the order number.
