Switching On and Off

I
the On/Off switch 4 toward the
O
rear and then press the On/Off
switch 4.

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.
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 sharp-
ened with the drill bit sharpener (see accesso-
ries).
