Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V can
also be operated with 220 V.
Reversing the Rotational Direction (GBM 6 RE)
The rotational direction switch 5 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 4 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 5 left to the
stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 5 through to the right stop.
Switching On and Off
To start the machine, press the On/Off switch 4
and keep it depressed.
To lock the pressed On/Off switch 4, press the
lock-on button 3.
To switch off the machine, release the On/Off
switch 4 or when it is locked with the lock-on but-
ton 3, briefly press the On/Off switch 4 and then
release it.
Adjusting the Speed (GBM 6 RE)
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 4 is pressed.
Light pressure on the On/Off switch 4 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Bosch Power Tools

Working Advice

Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts
can slip off.
For drilling in metal, use only perfectly sharp-
ened HSS drill bits (HSS=high-speed steel). The
appropriate quality is guaranteed by the Bosch
accessories program.
Twist drills from 2.5–10 mm can easily be sharp-
ened with the drill bit sharpener (see accesso-
ries).
We recommend the use of a drill stand (see ac-
cessories) for work where greater precision is
particularly required.
The machine vice, which is available as an acces-
sory, enables secure clamping of workpieces.
This prevents the workpiece from turning and
any accidents this would cause.
Belt Clip
With the belt clip 2, the machine can be hung on-
to a belt. The user has both hands free and the
machine is always at hand.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article number
given on the type plate of the machine.
