If the preselected torque is reached during
screwdriving, the machine switches off; the drill-
ing tool no longer rotates. If the load on the ma-
chine is then removed with the On/Off switch
6
still pressed, the drilling tool continues to run on-
ly at very low speed for safety reasons.
After briefly releasing the On/Off switch
6
, the
next screw can be driven in with the same
torque.
For
screwdriving without torque lim-
itation
, turn the thumbwheel
3
to the
right stop. This setting is required,
when the torque in position
III
is not
sufficient.
Working Advice
f
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 tiles, set the selector switch
2
to
the “Drilling” symbol. Do not switch over to the
symbol “Impact Drilling” or work with impact un-
til after drilling through the tile.
Use carbide tipped drill bits when working in
concrete, masonry and brick wall.
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).
