Inspect the saw chain for the most
9.4
worn-out cutting tooth and start sharp-
ening this tooth. The most worn-out
cutter is important in order to sharpen
all other cutters to the same depth.
Mark the first sharpened cutter in a
suitable way (e. g. with chalk).
Loosen the fastening lever (9), lift the
9.5
chain stop (10) and move the chain so
that the cutter after the next one can be
sharpened (see Fig. K).
Secure the chain with the fastening
9.6
lever (9) and sharpen this tooth. Make
sure not to sharpen the cutter too much
in order not to damage the body of the
cutter! (See Fig. L).
Sharpen every second cutting tooth in
9.7
one direction. Then turn the angle of the
chain holder assembly (8) to the
needed angle in opposite direction (see
Fig. K).
10. Operation – Grinding the cutters
on the opposite
Turn the chain holder assembly (8) only
when the grinding disc is not moving.
To sharpen the remaining cutters on the
10.1
opposite, first switch off the device and
pull the battery.
Loosen the locking screw (6) and turn
10.2
the chain holder assembly (8) in the
opposite direction up to the corre-
sponding angle. Re-tighten the locking
screw (see Fig. N).
Also mark the first sharpened cutter
10.3
and proceed as stated in the chapter
„Operation – Sharpening the Cutters", in
order to sharpen the remaining cutters
(see Fig. M).
11. Notes for the grinding disc to be
used
To avoid injuries always use suitable grind-
ing discs that are in proper condition!
With the simple sound test you can check
the disc for cracks and damages. Hang up
the grinding disc so it can swing freely (e. g.
on a thick thread) and knock the disc edge
with an object. The disc should give a clear
and high pitch sound. If the sound is
damped or blank, the grinding disc is defec-
tive and should not be used furthermore.
Make sure before carrying out any work on
the saw chain sharpener that the battery is
removed.
12. Changing the grinding disc
Switch off the machine and remove the
12.1
battery!
Remove the protective cover (2).
12.2
Unscrew the 3 retaining screws (see
Fig. O).
Hold the grinding disc (14) firmly with
12.3
one hand and loosen the flange nut by
turning counter clockwise (see Fig. P).
Replace the grinding disc by a new one.
12.4
Tighten the flange nut by turning clock-
12.5
wise and hand-tight only.
Mount the flange nut on the grinding
disc from the correct side (see Fig. Q)
Please observe the direction rotation
on the grinding disc. The direction
rotation of the spindle is additionally
marked on the grinding disc protective
cover (2).
Mount the protective cover (2) on the
12.6
machine. Only use grinding discs with
an outer diameter of 108 mm and with
an inner diameter of 23 mm.
The grinding speed from replacement
discs must meet or exceed the rpm
rating of the machine.
13. Set the depth limiter spacing
(See Fig. R).
Once the chain has been fully sharpened,
you must make sure that the depth limiter
spacing is kept. The depth limiters (17)
must be lower than the cutting tooth (16).
You may need to file the depth limiters (17)
to the specifications for your chain using a
file (not included in delivery).
14. Cleaning and maintenance
Cleaning
14.1
• Remove the battery from the device
before cleaning or maintaining the
machine.
• Keep safety devices, ventilation openings
and the motor housing as free as possi-
