7. Use
7.1 Switching On and Off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
The machine must not be allowed to draw in
additional dust and shavings. When switching
the machine on and off, keep it away from dust
deposits. After switching off the machine, only place
it down when the motor has come to a standstill.
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 at the intended handles, take a secure
stance and concentrate on the work.
See illustration A on page 2.
Torque activation

Continuous operation (depending on features)
Switching on: Slide the lock (4) in the direction of the
arrow, press the trigger (5) and keep it
pressed. The machine is now switched on.

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.
Separating:
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.

move back and forth so that the surface of the
workpiece does not become too hot.
Wire brushing:
Press down the machine evenly.
8. Cleaning
Motor cleaning: blow compressed air through the
rear ventilation slots of the machine regularly,
frequently and thoroughly. Here, the machine must
be held firmly.
Button (6) for adjustment of the handle
(depending on features): Occasionally blow
compressed air through the button (when pressed,
in all 3 main handle positions).

9. Troubleshooting

- Switching on procedures produce brief reductions
in voltage. Unfavourable power conditions can be
detrimental to other devices. Power impedances
smaller than 0.2 ohm should not cause any
malfunction.
10. Accessories
Use only genuine Metabo accessories.
If you need any accessories, check with your
dealer.
The dealer needs to know the exact model
designation of your power tool in order to select the
correct accessory.
