6 Special Product Features
Metabo S-automatic safety clutch:
If the insertion tool jams or hooks, the power flow to
the engine will be restricted. Because of the high
power which then arises, always hold the machine
with both hands on the handles, stand safely, and
concentrate on your work.
Turn-off carbon brushes: If the brushes are
completely worn, the machine switches off
automatically.

With VTC electronics: A LED warns before the
brushes are completely worn.
Restart protection with VTC electronics:

The restart protection prevents the machine from
starting unintentionally when being plugged in
again or when power is restored after a power
failure.
Overload protection indicator with VTC
electronics:
(BE 1020)
The overload protection indicator issues a warning
if the machine is overloaded.
7 Initial Operation
Before plugging in, check to see that the
rated mains voltage and mains frequency,
as stated on the rating label, match with your
power supply.
To ensure that the drill chuck is securely
fitted: After initial drilling (clockwise), use a
screwdriver to tighten the safety screw firmly
inside the drill chuck. This safety screw is model-
specific and as such may not be in all models. THE
SAFETY SCREW HAS A LEFT-HANDED THREAD!
(see section 8.8)
7.1 Side handle installation
For safety reasons, always use the side
handle supplied.
Open the clamping ring by turning the side handle
(10) counter-clockwise. Place the side handle onto
the machine's collar. Tighten the side handle in the
required angle depending on the task at hand.
8 Use
8.1 Switching On and Off
To start the machine, press the trigger (8).
The speed can be changed at the trigger.

accelerates continuously up to the pre-selected
speed.
For continuous operation the trigger can be locked
with the lock button (6). To stop the machine,
press the trigger again.
If switched on continuously, the machine
continues running if it is jerked out of your
hands. Therefore, always hold the machine
with both hands on the handles, stand safely,
and concentrate on your work.
