Changing the saw chain
Never fix a new saw chain on a
worn set of teeth or on a damaged
or worn blade.
1. Switch off the equipment and discon
-
nect from the mains.
2. Undo the blade fixing screw (
5)
and take off the chain wheel cover (
6)
3. Take off the old saw chain (
2).
The assembly and tensioning of the new
saw chain are described in the “Assem-
bly” chapter.
Maintaining the blade
Use cut-protection gloves when
handling the chain or the chain
bar.
1. Switch off the saw and pull out the
power plug (
A
31).
2. Remove the sprocket chain wheel
covering (6), the saw chain (2) and
the chain bar (3).
3. Check the chain bar (3) for wear. Re-
move burrs and straighten the guide
surfaces with a flat file.
4. Clean the oil passages (
B
27) of
the chain bar, in order to guarantee
a trouble-free, automatic oiling of the
saw chain during operation.
5. Mount chain bar (3), chainsaw (2) and
sprocket chain wheel covering (6) and
tighten the chainsaw.
When the oil channels are in opti-
mum condition, the saw chain au-
tomatically sprays a little oil a few
seconds after the saw is started.
The chain bar (3) must be turned round
every 10 working hours, in order to guar-
antee uniform wear.
Turning over the bar (3) requires you to
move the tensioning screw (
N
30a) to the
other side of the bar. Unscrew the retain-
ing bolt (
N
30b) 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 (
N
30b) in.
Maintenance intervals
Carry out the maintenance work listed
in the table below at regular intervals.
Regular maintenance of your equipment
extends the lifespan of the equipment.
You will also achieve optimum cutting per-
formances and avoid accidents.
