10. Troubleshooting

Machine with "WE..." in the model designation:
- Overload protection: The electronic signal
display (6) lights up and the load speed
decreases dramatically. The motor temperature
is too high! Run the machine in idling until it cools
down and the electronic signal display switches
off.
- Overload protection: The electronic signal
display (6) lights up and the load speed
decreases slightly. The machine is overloaded.
Work with a reduced load until the electronic
signal display goes out.
- Electronic safety stop: The electronic signal
display (6) lights up and the machine was
SWITCHED OFF automatically. If the slew rate
of the current is too high (for example, if the
machine suddenly seizes or kickback occurs), the
machine switches off. Switch off the machine at
the trigger switch (8). Switch it on again and
continue to work as normal. Try to prevent the
machine from seizing. See Section 4.2.
- Restart protection: The electronic signal
display (6) FLASHES and the machine does
not start. The restart protection is active. If the
mains plug is inserted with the machine switched
on, or if the power 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 22-180 MVT, W 22-230 MVT, W 24-180 MVT,
W 24-230 MVT, W 26-180 MVT, W 26-230 MVT:
- Switching on the machine reduces the voltage
briefly. Unfavourable mains power conditions may
have a detrimental effect on other machines.
Power impedances less than 0.2 ohm should not
cause malfunctions.
11. Accessories
Use only genuine Metabo accessories.
Use only accessories which fulfil the requirements
and specifications listed in these operating
instructions.
Fit accessories securely. Secure the machine if it is
operated in a bracket. Loss of control can cause
personal injury.

13. Environmental Protection

The generated grinding dust may contain harmful
substances. Dispose appropriately.
Observe national regulations on environmentally
compatible disposal and on the recycling of disused
machines, packaging and accessories.
Only for EU countries: Never dispose of
power tools in your household waste! In
accordance with European Directive 2002/
96/EC on waste electrical and electronic equipment
and its implementation in national legal systems,
used power tools must be collected separately and
handed in for environmentally compatible recycling.
