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 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 set-
ting 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: Assembly,
ten-
sioning chainsaw.
Starting up a new saw chain
In the case of a new chain, the tensioning
force decreases after some
time. There-
fore, you have to re-tension the chain af-
ter the first 5 cuts and no later than after
10 minutes’ sawing time.
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 se-
rious injury.

Maintaining the chain bar
Use cut-protection gloves when
handling the chain or the chain
bar.
1. Switch off the saw and pull out the
power plug (12).
2. Remove the sprocket chain wheel
covering (8), the saw chain (5) and the
chain bar (4).
3. Check the chain bar (4) for wear. Re-
move burrs and straighten the guide
surfaces with a flat file.
4. Clean the oil passages (
26) of
the chain bar, in order to guarantee a
trouble-free, automatic oiling of the
saw chain during operation.
5. Mount chain bar (4), chainsaw
(5) and sprocket chain wheel covering
(8) 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.
F
Turn the chain bar
Use cut-protection gloves when
handling the chain or the chain
bar.
The blade (4) has to be reversed regularly
after a working time of approximately 10
hours in order to ensure even wear.
