rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Setting the rotational direction
The rotational direction switch (7) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (6) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (7) through to the right stop.
Left rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (7) through to the left
stop.
Mechanical Gear Selection
You can press the gear selector switch (8) with the
u
power tool off or on. You should not do this at full load
or maximum torque, however.
Gear I:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Gear II:
High speed range; for working with a small drilling diameter.
If the gear selector (8) cannot be swivelled all the way to the
stop, turn the drive spindle slightly with the drill.
Preselecting speed
You can preselect the required speed/impact rate using the
speed preselection thumbwheel (5), even during operation.
The required speed is dependent on the material and the
work conditions and can be determined by practical trials.
Switching on/off
To start the power tool, press and hold the on/off switch
(6).
Press the lock-on button (4) to lock the on/off switch (6) in
this position.
To switch off the power tool, release the on/off switch (6);
or, if the switch is locked with the lock-on button (4), briefly
press the on/off switch (6) and then release it.
Overload clutch
The power tool is equipped with an overload clutch (anti-ro-
tation) to limit high torque reactions.
If the application tool jams or snags, the power trans-
u
mission to the drill spindle will be interrupted. Always
hold the power tool firmly with both hands to with-
stand the forces this may create and adopt a position
with stable footing.
Switch the power tool off immediately and remove the
u
application tool if the power tool becomes blocked.
Switching on when the drilling tool is blocked may
cause high torque reactions.
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (6) to varying extents.

A light pressure on the on/off switch (6) results in a low rota-
tional speed. Increased pressure on the switch causes an in-
crease in speed.
Practical advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
When drilling into metal, only use sharpened HSS drills (HSS
= high-speed steel) which are in perfect condition. The
Bosch accessory range guarantees appropriate quality.
Using the drill bit sharpener (accessory), you can effortlessly
sharpen twist drill bits with a diameter of 2.5–10 mm.
The machine vice, which is available as an accessory, en-
ables the workpiece to be securely clamped. This prevents
the workpiece from turning and any accidents this could
cause.
