switches off (see 14b).
After switching on the device, wait until the device has
reached its max. speed. Only then must you start with
the grinding.
The disk will continue to run after the equipment is
switched off. There is a risk of injury.
Test run:
Before starting work and after each change of grinding
disk, carry out a test run of at least 60 seconds with
no load.
Switch off the equipment immediately if the disk runs
lumpy, substantial vibrations occur, or abnormal noises
are generated.
Grinding with the grinding disc
The arrow on the protective hood ( 3) shows the direc-
tion of rotation of the grinding disc.
• Place the workpiece on the workpiece support ( 18)
and slowly bring it to its desired angle on the grinding
disc ( 19).
• Move the workpiece slightly from side to side in or-
der to achieve an optimal grinding result. This way, the
grinding disc is worn uniformly. Occasionally, allow the
workpiece to cool down.
Tape loops
The arrow on the protective hood ( 9) shows the direc-
tion of rotation of the grinding belt.
• Firmly hold the workpiece, do not exert any strong
force.
• Move the workpiece slightly from side to side in order
to avoid a one-sided wear of the grinding belt.
• Always grind the pieces of wood in the direction of the
wood grain in order to avoid chipping.
Change grinding belt
1. Loosen the 3 fixing screws (11) and hang out the
grinding belt cover (12).
2. Loosen the clamping screw (8) by a few rotations.
3. Press the clamping lever (7) downwards and detract
the grinding belt (10).
4. Place the new grinding belt (10) in the centre on the
upper (20a) and lower (20b) rollers and let go of the
clamping lever (7).
5. Tighten the clamping screw (8) and mount the grin-
ding belt cover (12). Set the tape run:
6. Loosen the nut (21a) of the ad justable screw (21)
with a ring spanner. The tape run accuracy is set by the
turning the adjustable screw (21) with a screwdriver.
7. Check the tape run by manually turning the grinding
belt.
8. Re-tighten the nut (21a). Change grinding disc
Information on replacement:
• Never operate the device without protective equip-
ment.
• Ensure that the rotation speed stated on the grinding
disc ( 19) is the same or higher than the nominal rota-
tion speed of the device.
• Ensure that the grinding disc dimensions match tho-
se of the device.
• Only use flawless grinding discs (ringing test: when
you strike the grinding disc with a plastic hammer,
it results in a clear sound).
• Never re-drill a locating hole which is too small to
make it larger.
• Never use separate bushings or adapters in order to
make grinding discs whose hole is too large
fit the device.
• Do not use any saw blades.
• To clamp the grinding tools only use the clamping
flange provided.
The pads between the clamping flange and the grin-
ding tools must be made of elastic materials e.g.,
rubber, soft cardboard etc.
• Always reassemble the device completely after repla-
cing the grinding disc.
Switch the device off and remove the mains plug.
Allow the device to cool down.
Wear protective gloves when changing the grinding
discs in order to avoid cutting damages.
1. Remove the spark protection ( 1) (see „Assemble/
set spark protection).
2. Loosen the 3 fixing screws (15) and remove the
grinding disc cover (16).
3. Loosen the fixing screws (11) and remove the grin-
ding belt cover (12) (see „Changing the grinding
belt").
4. Unscrew the grinding disc nut (19a) in the clockwise
direction, by holding the nut of the opposite
roller of the grinding belt in place (see small image).
5. Remove the clamping flange (19b) and the grinding
disc (19).
6. Set up the new grinding disc (19) and the clamping
flange and manually screw the grinding disc
nut (19a) in the anti-clockwise direction.
7. Screw the grinding disc cover (16).
8. Set the spark protection ( 1) and the workpiece
support ( 18) so that the distance between the grinding
disc (19) is max. 2 mm (see „Assembly").
The grinding disc nut must not be screwed too tightly in
order to avoid a breaking of the grinding disc and nut.
Test run:
Before starting work and after each change of grinding
disk, carry out a test run of at least 60 seconds with
no load.
Switch off the equipment immediately if the disk runs
lumpy, substantial vibrations occur, or abnormal noises
are generated.
CLEANINg AND mAINTENANCE
Disconnect the plug before adjustment, maintenance
or repair.
Have any work not described in these instructions ca-
rried out by a specialist workshop.
Use only original components. Allow the equipment to
cool before carrying out any maintenance and clea-
ning work.
There is a risk of burns.
Before each use, check the equipment for obvious
defects such as loose, worn or damaged components
and check that screws or other parts are sitting co-
rrectly. In particular, check the grinding disk (
19). Replace damaged parts.
