6. Attaching the grinding wheel

Before carrying out any modifications: remove
the battery pack from the machine. The
machine must be switched off and the spindle at a
standstill.
For reasons of safety, attach the safety guard
for cut-off grinding before performing Abrasive
Cutting-Off Operations (see chapter 10.
Accessories).
6.1 Locking the spindle
- Press in the spindle locking button (3) and turn the
spindle
(2) by hand until you feel the spindle locking
button engage.
6.2 Placing the wheel in position
See illustration C on page 2.
- Fit the support flange (1) on the spindle. The
flange should not turn on the spindle when
properly attached.
- Place the grinding wheel on the support flange (1).
The grinding wheel must lay flat on the supporting
flange. The metal flange on the cut-off wheel must
lay flat on the support flange.
Note: The support flange (1) is secured to prevent it
from falling off. To remove: use some force if
necessary.
6.3 Securing/releasing the clamping nut
Securing the clamping nut (15):
The 2 sides of the clamping nut are different. Screw
the clamping nut onto the spindle as follows:
See illustration D on page 2.
- A) For thin grinding wheels:
The edge of the clamping nut (15) faces upwards
so that the thin grinding wheel can be attached
securely.
B) For thick grinding wheels:
The edge of the clamping nut (15) faces
downwards so that the clamping nut can be
attached securely to the spindle.
- Lock the spindle. Turn the clamping nut (15)
clockwise using the 2-hole spanner (16) to
secure.
Releasing the clamping nut:
- Lock the spindle (see chapter 6.1). Turn the
clamping nut (15) anticlockwise using the 2-hole
spanner (16) to unscrew.

7.2 Working instructions
Grinding:
Press down the machine evenly on the surface and
move back and forth so that the surface of the
workpiece does not become too hot.
Roughing: position the machine at an angle of 30° -
40° for the best working results.
Cutting-off:
Always work against the run of the disc
(see illustration). Otherwise there is
the danger of the machine kicking

the machine evenly at a speed
suitable for the material being processed. Do not tilt,
apply excessive force or sway from side to side.
Sanding:
