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 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: Starting operation,
tensioning chainsaw.
• Switch off the saw and pull out the
power plug.
• 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. 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 se-
rious injury.

Maintaining the chain bar

Use cut-protection gloves when
handling the chain or the chain
bar.
The chain bar must be turned round every
10 working hours, in order to guarantee
uniform wear.
1. Switch off the saw and pull out the
power plug (18).
2. Remove the sprocket chain wheel cov-
ering (15), 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 (
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 (15)
and tighten the chainsaw.
Turning over the bar (4) requires you to
move the tensioning screw (
other side of the bar. Unscrew the retain-
ing bolt attaching the bar to the tensioning
screw. Move the tensioning screw over
to the other side of the bar and screw the
retaining bolt back in.
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.
