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 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.
1. Remove the saw chain (refer

W
to the section on operating
the saw). The chain should be
well-tensioned to ensure proper
sharpening.
2. 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!
3. 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.
4. Sharpen first the teeth on one
side. Turn the saw around and
sharpen the teeth of the other side.
5. The chain is worn and must be
replaced by a new saw chain if
only approx. 4 mm of the cutting
teeth is remaining.
6. After the sharpening, all cutting
elements must now be equal in
length and width.

7. After every third sharpening, the
sharpness depth (depth limita-
tion) 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 little at the front.
Adjusting the chain tension

•
Switch off the device and remove the
battery from the device
•
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.
Starting up a new saw chain
In the case of a new chain, the tensioning
force decreases after some time. Therefore
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.
Maintaining the chain bar
Use cut-protection gloves when
handling the chain or the chain bar.
