when you are withdrawing it.
4. Sharpen fi rst 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 fi led with the aid of a fl at
fi le. 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
The adjustment of the chain tension is de-
scribed in the chapter “Assembly - tension-
ing chainsaw”.
• Switch off the device and remove the
battery (16) 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 have to re-tension the chain after the
fi rst 5 cuts and no later than after 10 min-
utes’ sawing time.
Approved saw chains:
Oregon 90PX040X,
Trilink CL14340TL.
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, poten-
tially leading to serious injury.
Maintenance intervals
Regularly carry out the maintenance opera-
tions listed in the following table. The life
of the saw is extended by regular main-
tenance of your chainsaw. Furthermore,
you get optimum cutting performance and
avoid accidents.
