Test run:
Before starting work and after each
change of grinding disk, carry out a test
run of at least 30 seconds with no load.
Switch off the equipment immediately if
the disk runs lumpy, substantial vibrations
occur, or abnormal noises are generated.
Sharpening the saw chain
When working with the saw chain,
keep clean the ventilation openings
(see "Maintenance and cleaning").
An incorrectly sharpened saw
chain may damage the chain the
increase the risk of the saw jump-
ing back.
Ensure that the chain is aligned
accurately.
Observe the correct rake angle
and minimum dimensions of the
saw chain. Remove as little mate-
rial as possible.
Do not grind in drive
(a) or connecting (b)
links, otherwise the
saw chain may rupture.
In the event of non-observance,
there is a risk of accidents when
handling the chainsaw.
Instructions for sharpening
•
Clean the saw chain before you
sharpen it. Use a brush or cloth to re-
move oily wood chips or residual oil.
•
After sharpening, all cutting links must
be of equal length and width.
•
The chain is worn and must be re-
placed with a new saw chain if only
approx. 4 mm of cutting tooth remain.
Inserting the saw chain:
1. To open the chain guide, turn the
clamping lever (13) anticlockwise. You
must first return the clamping lever to
its home position several times.
The clamping lever unlocks by pulling
it outward, returning it to the home po-
sition and allowing it to snap back in.
2. Place the saw chain in the chain guide
(7). Ensure that the cutting edges face
the grinding disk (18).
3. Flap down the chain stop (15) and pull
the saw chain back until the cutting
tooth (27) to be sharpened contacts
the stop (see figure
Adjusting the sharpening angle:
4. Loosen the locking
screw (10) and use the
scale (11) on the rotary
disk of the chain clamping
unit (12) to set the correct
sharpening angle α.
Tighten the locking screw.
Adjusting the stop:
5. Turn off the motor and pull down the
grinding head (2) by the handle (4).
6. Turn the chain feed adjusting screw
(14a) to move the cutting tooth (27)
towards the grinding disk (18) until
they make contact (see figure
Tighten the adjusting nut (14b) to lock
the adjusting screw (14a).
7. Turn the clamping lever (13) clockwise
to tighten the chain links in the chain
guide (7) (see 1.).
8. Turn the adjusting screw (6a) to set
the depth stopper such that the grind-
ing disk (18) contacts the tooth root
(see figure
