Files and how to work with them
Sharpen using a special
Þ
le holder with a saw chain round
Þ
le.
Normal round
Þ
les are not appropriate for this work. See „Ac-
cessories“ for the order number.
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.
Always guide the
Þ
le horizontally (10
°
to the guide bar).

The
Þ
le holder makes
Þ
le guidance easier. It is marked for the
correct sharpening angle of 25° (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 (

). See „Accessories“ for the order number.
Round off the front of the depth limiter (
