8.2 Working instructions
Grinding and sanding operations:
Press down the machine evenly on the surface and
move back and forth so that the surface of the work-
piece does not become too hot.
Roughing: position the machine at an angle of 30° -
40° for the best working results.
Cutting-off:
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 suit-
able for the material being processed. Do not tilt,
apply excessive force or sway from side to side.
Wire brushing:
Press down the machine evenly.
9. 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.
Clean the dust filter regularly: remove and clean
with a jet of compressed air.
10. Troubleshooting
10.1 Mains powered machines:
- Overload protection: There is a MAJOR
reduction in load speed. The motor temperature
is too high! Allow the machine to run at idle speed
until it has cooled down.
- Overload protection: There is a SLIGHT
reduction in load speed. The machine is over-
loaded. Reduce the load before continuing to
work.
- Metabo S-automatic safety shutdown: The
machine was SWITCHED OFF automatically. If
the slew rate of the current is too high (for
example, if the machine suddenly seizes or kick-
back occurs), the machine switches off. Switch off
the machine at the slide 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 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 inter-
ruption, the machine does not start up. Switch the
machine off and on again.
10.2 Cordless machines:
- The electronic signal display (12) lights up
and the load speed decreases. The tempera-
ture is too high! Run the machine in idling until the
electronics signal indicator switches off.
- The electronic signal display (12) flashes and
the machine does not start. The restart protec-
tion is active. The machine will not start if the
battery pack is inserted while the machine is on.
Switch the machine off and on again.
