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 486: Use 11/64" (4,5 mm) dia. round saw-chain le.
Type 496: Use 7/32" (5,5 mm) dia. round saw-chain le.
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 (10° to the guide bar).
A le holder makes le guidance easier. It is marked for the
correct sharpening angle of:
α = 25°
(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).
