8. Maintenance, cleaning
Clean, check and perform maintenance work on the

setting, cleaning, maintenance or repair work.
8.1
Grinding wheel change
Use only original Metabo grinding wheels.
The permissible rotational speed specified on
the grinding wheel must be equal to or greater
than the maximum idling speed specified on the
identification plate of the machine.
Grinding wheel check:
suspend the grinding wheel on a thread.
Knock lightly with a piece of hard wood. You will
hear a clear tone if the grinding wheel is in perfect
condition. If you hear a clattering, dull or hollow
sound, the grinding wheel is damaged.
Do not use damaged grinding wheels.

be carried out after the grinding wheel has been
changed. All persons must stay clear of the danger
zone when this is performed.
