Deviations from the measure-
ment data of the cutting geom-
etry can lead to an increase of
the spring-back slope of the
machine. Increased danger of
accident!
Special tools are necessary for sharpen-
ing the chain, which guarantee that the
cutting edges are sharpened at the cor-
rect angle and to the correct depth. For
the inexperienced 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.
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 en-
sure proper sharpening.
3. For the sharpening, a round file with
4.0 mm diameter is necessary.
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 with-
drawing 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 re-
placed by a new saw chain if only
approx. 4 mm of the cutting teeth is
remaining.
7. After the sharpening, all cutting ele-
ments 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 limi-
tation should be set back about 0.65
mm from the cutting tooth. After the
setting back of depth limitation, round
it off a little at the front.
Adjusting the chain tension
The adjustment of the chain tension is
described in the chapter: Starting opera-
tion, tensioning chainsaw.
• Switch off the saw and pull out the
power plug.
• Check the chain tension regularly and
adjust as often as possible. When
pulling on the saw chain with 9 N
(approx. 1 kg) tensile force, the saw
chain and blade must have a gap of
no more than 2 mm.
Starting up a new saw chain
In the case of a new chain, the tensioning
force decreases after some time. There-
fore you must re-tension the chain after
the first 5 cuts and at longer intervals
after this.
Never attach a new chain to a
worn drive pinion or place onto
a damaged or worn chain bar.
The chain could spring back or
break, potentially leading to seri-
ous injury.
