1st gear:
Low speed range; for working with large drill-
ing diameter.
2nd gear:
Higher speed range; for working with small
drilling diameter.
If the gear selector 2 cannot be fully engaged, lightly rotate
the drive spindle with the drill bit by twisting the drill chuck.
Switching On and Off
To start the machine, press the On/Off switch 4 and keep it
pressed.
Lock the pushed On/Off switch 4 by
pushing the lock-on button 3 upward.
To switch off the machine, release the On/Off switch 4 or
when it is locked with the lock-on button 3, briefly press the
On/Off switch 4 and then release it.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 4 is pressed.
Light pressure on the On/Off switch 4 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Working Advice
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is guar-
anteed by the Bosch accessories program.
Twist drills from 2.5–10 mm can easily be sharpened with
the drill bit sharpener (see accessories).
We recommend the use of a drill stand (see accessories) for
work where greater precision is particularly required.
The machine vice, which is available as an accessory, enables
secure clamping of workpieces. This prevents the workpiece
from turning and any accidents this would cause.
