Reversing the Rotational Direction
Actuate the rotational direction switch 1
only when the machine is at a standstill.
The rotational direction switch 1 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 1 to
"R".
Left rotation: For loosening or unscrewing
screws and nuts, push the rotational direction
switch 1 to "L".
Switching On and Off
To start the machine, firstly pull
I
the On/Off switch 4 toward the
O
rear and then press the On/Off
switch 4.
To lock-on, pull the On/Off
F
I
switch 4 toward the rear, press
O
the On/Off switch 4 and pull it
further toward the rear.
To switch off the machine, release the On/Off
switch 4. When the On/Off switch 4 is locked,
press it first and then release it.
Adjusting the Speed
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.
Preselecting the Speed
The required speed can be preselected with the
thumbwheel 2 (also while running).
Working Advice
Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts
can slip off.
Bosch Power Tools
Tips
After longer periods of working at low speed, al-
low the machine to cool down by running it for
approx. 3 minutes at maximum speed with no
load.
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
sharpened with the drill bit sharpener (see ac-
cessories).
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.
WARNING! Important instructions for con-
necting a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it
must be disposed of safely.
