Do not use the “Quick-R” clamping nut if the accessory has a clamping shank thicker than 6.8 mm!
In this case, use the 2-hole nut (13) with 2- hole spanner (14).
- Lock the spindle (see chapter 6.1).
- Position the "Quick-R" clamping nut on the spindle so that the 2 lugs engage in the 2 grooves on the spindle.
(1) (3) See illustration on page 2.
- Tighten the "Quick “clamping nut by turning clockwise by hand.
- Turn the grinding wheel firmly clockwise to tighten the "Quick “clamping nut.
Releasing the clamping nut (1):
Only when the “Quick-R” clamping nut (1) is attached must the spindle be stopped using
the Quick-R spindle locking button (4).
- The machine continues to run after switching off.
- Press in the Quick-R spindle locking button just before the grinding disc stops. (4) The “Quick-R”
clamping nut (1) loosens itself by around half a turn and can be removed without additional effort or tools.
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, and 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.
Machines with slide switch:
Switching on: Push the sliding switch forward. (5) For continuous activation, now tilt downwards until it
engages.
Switching off: Press the rear end of the slide switch (5) and release it.
