6.4 Securing/Releasing the 2-hole nut
(depending on features)
Securing the 2-hole nut (13):
The 2 sides of the 2-hole nut are different. Screw the
2-hole nut onto the spindle as follows:
See illustration B on page 2.
- X) For thin grinding discs:
The edge of the 2-hole nut (13) faces upwards so
that the thin grinding disc can be attached
securely.
Y) For thick grinding discs:
The edge of the 2-hole nut (13) faces downwards
so that the 2-hole nut can be attached securely to
the spindle.
- Locking the spindle. Turn the 2-hole nut
(13)clockwise using the 2-hole spanner (14) to
secure.
Releasing the 2-hole nut:
- Lock the spindle (see chapter 6.1). Turn the 2-hole
nut (13) anticlockwise using the 2-hole spanner
(14) to unscrew.
7. Use
7.1 Adjusting the speed (depending on
features)
Set the recommended speed at the thumbwheel.
(8) (small number = low speed; large number = high
speed)
Cutting disc, roughing disc, cup wheel and diamond
cutting disc: high speed
Brush: medium speed
Sanding plate: low to medium speed
Note: We recommend using our angle polisher for
polishing work.
7.2 Switching On and Off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
Avoid inadvertent starts: always switch the
tool off when the plug is removed from the
mains socket or if there has been a power cut.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
both hands using the handles provided, stand
securely and concentrate.
Avoid the machine swirling up or taking in dust
and chips. After switching off the machine,
only place it down when the motor has come to a
standstill.

7.3 Working Directions
Grinding and sanding operations:
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.
Rough grinding: position the machine at an angle of
30° - 40° for the best working results.
Abrasive cutting-off operations:
Always work against the run of the disc
(see illustration). Otherwise there is
the danger of the machine kicking
back from the cut out of control. Guide
the machine evenly at a speed
suitable for the material being processed. Do not tilt,
apply excessive force or sway from side to side.
