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) to-
wards the grinding disk (18) until they
make contact (see figure
). Tighten
the adjusting nut (14b) to lock the ad-
justing 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 grinding
disk (18) contacts the tooth root (see
figure
). Tighten the adjusting nut
(6b) to set the grinding depth.
Sharpen:
9. Switch on the equipment (see “switch-
ing on and off “).
10. By putting gentle pressure on the han-
dle (4), move the grinding head (2)
upwards and sharpen the cutting tooth.
Do not allow the grinding disk (18)
to slow down to standstill. This is pre-
vented by reducing the pressing force
early enough.
11. Switch off the equipment to move the
chain onwards.
Loosen the clamping lever (13) and
tighten the next chain link to be sharp-
ened in the chain guide (7) using
the adjusted chain stop (15) and the
clamping lever.
Start by sharpening the teeth on
one side of the chain. Then adjust
the rake angle and sharpen the
teeth on the other side.
Check.the.depth.limiter.distance.
(see. .image.
):
The cutting links, which comprise a cutting
tooth (27) and a depth limiter lug (28), are
the sawing parts of the chain. The height
distance between these two is determined
by depth limiter distance A.
1. After every third sharpening process,
check depth limiter distance A against
the saw chain manufacturer’s specifica-
tions.
2. Use a flat file to file down the height
of the depth limiter lug (28) and, after
resetting, round off the depth limiter lug
a little. The original shape must remain
intact.
