Other diameters damage the
chain and can lead to danger dur-
ing work!
4. Sharpen only from the inside to the out-
side. 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 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 sharp-
ness depth (depth limitation) 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
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. 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 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.
