8.1

Setting speed

The speed can be preset via the setting wheel (5)
and is infinitely variable.
Positions 1-6 correspond approximately to the
following no-load speeds:
1......... 900 / min
2......... 1700 / min
3......... 2350 / min
The VTC electronics make material-compatible
work possible and an almost constant speed, even
under load.
8.2 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.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
both hands using the handles provided, stand in a
safe position and concentrate.

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.
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
overloaded. 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
kickback occurs), the machine switches off.
Switch off the machine using the slide switch (3).
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 power supply is restored following an
interruption, the machine does not start up. Switch
the machine off and on again.
