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 484: 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 092: Saw chain round Þ le, dia. 4.0 mm.
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.
Round off the front of the depth limiter (2).
