3. For the sharpening, a round file
with 4.0 mm diameter is neces-
sary.
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 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 lit-
tle at the front.
Adjusting the chain tension
The adjustment of the chain tension is de-
scribed in the chapter: Starting operation,
tensioning chainsaw.
Starting up a new saw chain
In the case of a new chain, the tensioning
force decreases after some
74
time. Therefore,
you have to re-tension the chain after the
first 5 cuts and no later than after 10 min-
utes' 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 serious
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 (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.
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.
Turn the chain bar
Use cut-protection gloves
when handling the chain or
the chain bar.
