Files and how to work with them
Use a special saw chain round le for sharpening. Standard round
les are unsuitable. For the order number, see “Accessories”.
Type 484: File the rst cutter half with a 3/16” (4,8 mm) dia. round
saw-chain le, then switch to a 11/64” (4.5 mm) dia. le.
Type 092: Saw chain round le, dia. 5/32” (4.0 mm).
The le should cut only when pushed forwards (arrow). Lift the
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 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 le holder makes 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 ling, see illustration)
and limits the cut depth to the correct 4/5 of the 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 at
le (1). See „Accessories“ for the order number.
Round off the front of the depth limiter (2).
