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 limita
-
tion 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 o
f 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
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 dam
-
aged or worn chain bar. The chain
could spring back or break, poten
-
tially leading to serious injury�
Maintaining the chain bar
Use cut-protection gloves when
handling the chain or the chain bar�
The blade must be inverted every 8-10 work-
ing hours in order to guarantee even wear
(see chapter “initial operation”).
1. Switch off the saw and pull out the
power plug.
2. Remove the sprocket chain wheel
covering, the saw chain and the chain
bar.
3. Check the chain bar for wear. Remove
burrs and straighten the guide sur-
faces with a flat file.
4. Clean the oil passages of the
chain bar (24), in order to guar-
antee a trouble-free, automatic
oiling of the saw chain during
operation.
5. Mount chain bar, chainsaw and
sprocket chain wheel covering and
tighten the chainsaw.
With the oil nozzles in good condi-
tion and the oil regulator set cor-
rectly, the saw chain will spray a
little oil off after starting.
