8. Use
8.1 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
Switching on: Slide the lock (4) in the direction of
the arrow and press the trigger (5).
Switching off: Release the trigger (5).
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.
Now slide the lock (4) in the direction of the
arrow once more to lock the trigger (5)
(continuous operation).
Switching off: Press the trigger (5) and release.
8.2 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.
Sanding:
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.
Wire brushing:
Press down the machine evenly.

9. Cleaning
It is possible that particles deposit inside the power
tool during operation. This impairs the cooling of
the power tool. Conductive build-up can impair the
protective insulation of the power tool and cause
electrical hazards.
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner or by blowing in dry air.
Prior to this operation, separate the power tool from
the power source and wear protective glasses and
dust mask.
10. Troubleshooting
Machine with "X" in the model designation:
- Restart protection: The machine does not
start. The restart protection is active. If the mains
plug is inserted with the machine switched on, or if
the current supply is restored following an
interruption, the machine does not start up. Switch
the machine off and on again.
- When switched on, the machine accelerates
to maximum speed very quickly, i.e. automatic
restriction of the starting current does not work
(soft start). An electronic error exists. Other
safety-related electronic functions are no longer
available. Have the machine repaired immediately
(see 12.).
W 2000, W 2200-230, W 2400-230:
- 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.
11. Accessories
Use only genuine Metabo accessories.
Use only accessories that fulfil the requirements
and specifications listed in these operating instruc-
tions.
Fit accessories securely. Secure the machine if it is
operated in a bracket. Loss of control can cause
personal injury.
