tion. The vertical separation distance
between these two determines the
sharpness depth.
• The following values must be noted in
sharpening the cutting teeth:
H
- Sharp edge angle (30°)
- Breast angle (85°)
- Sharpness depth (0.65 mm)
- Round file diameter (4.0 mm)
Deviations from the meas-
urement data of the cutting
geometry can lead to an
increase of the spring-back
slope of the machine. In-
creased danger of accident!
Special tools are necessary for sharpening
the chain, which guarantee that the cutting
edges are sharpened at the correct angle
and to the correct depth. For the inexperi-
enced user of chainsaws, we recommend
to have the saw chain sharpened by a
specialist or a specialist workshop. If you
think yourself capable of sharpening the
chain, you can acquire the special tools in
the specialist trade.
I 1. Switch the saw off and unplug it
from the mains.
2. Remove the saw chain (refer
to the section on operating the
saw). The chain should be well-
tensioned to ensure proper sharp-
ening.
3. For the sharpening, a round file
with 4.0 mm diameter is neces-
sary.
Other diameters damage the
chain and can lead to danger
during work!
4. Sharpen only from the inside to
the outside. Guide the file from
the inner side of the cutting teeth
to the outer side. Lift the file when
you are withdrawing it.
5. Sharpen first the teeth on one
side. Turn the saw around and
sharpen the teeth of the other
side.
6. The chain is worn and must be
replaced by a new saw chain if
only approx. 4 mm of the cutting
teeth is remaining.
7. After the sharpening, all cutting
elements must now be equal in
length and width.
8. After every third sharpening, the
sharpness depth (depth limitation)
must be checked and the height
filed with the aid of a flat file. The
depth limitation should be set back
about 0.65 mm from the cutting
tooth. After the setting back of
depth limitation, round it off a lit-
tle at the front.
Adjusting the chain tension
The adjustment of the chain tension is de-
scribed in the chapter: Starting operation,
tensioning chainsaw.
• Switch off the saw and pull out the
power plug.
• Check the chain tension regularly and
re-adjust this as often as possible.When
the saw chain is tensioned with 9 N
(approx. 1 kg), the gap between the
saw chain and the guide rail may not
be more than 2 mm.
