– Anticlockwise: To loosen and unscrew screws and nuts,
press the rotational direction switch (6) all the way to the
right.
Switching On/Off
– To switch on the power tool, press the on/off switch (8).
– To lock the on/off switch (8), press and hold it while also
pushing the lock-on button (7).
– To switch off the power tool, release the on/off switch
(8). If the on/off switch (8) is locked, press the switch
first and then release it.
Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when
it is on by pressing in the on/off switch (8) to varying ex-
tents.
Applying light pressure to the on/off switch (8) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
Changing the chiselling position (Vario-Lock)
You can lock the chisel in 13 different positions, so you can
select the optimum working position for each task.
– Insert the chisel into the tool holder.
– Turn the impact/mode selector switch (10) to the "Vario-
Lock" position.
– Turn the application tool to the required chisel position.
– Turn the impact/mode selector switch (10) to the "chis-
elling" position. With this, the tool holder is locked.
– Set the rotational direction for chiselling to clockwise.
Chiselling with lock function
To chisel for extended periods without pressing the on/off
switch (8), lock the on/off switch in "chiselling" operating
mode.
– To lock the power tool, press the on/off switch (8) down
fully whilst simultaneously pressing the lock-on
switch (7).
– To switch the lock off, press the lock-on button (7) again.
Note: If you switch to a different operating mode while the
on/off switch is locked, the power tool will switch off.
Practical Advice
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
Setting the drilling depth (see figure H)
You can use the depth stop (13) to set the required drilling
depth X.
– Press the button for depth stop adjustment (11) and in-
sert the depth stop into the auxiliary handle (12).
The fluting on the depth stop (13) must face downwards.
– Insert the SDS-plus application tool into the SDS-plus tool
holder (3) to the stop. Otherwise, the movability of the
SDS-plus drilling tool can lead to incorrect adjustment of
the drilling depth.
Bosch Power Tools
– Pull the depth stop far enough out that the distance
between the drill bit tip and the edge of the depth stop
corresponds to the required drilling depth X.
Overload clutch
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.
Inserting screwdriver bits (see figure I)
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
A universal holder (20) with SDS-plus shank (accessory) is
required to work with screwdriver bits.
– Clean and lightly grease the insertion end of the shank.
– Insert the universal holder into the tool holder while turn-
ing it until it locks automatically.
– Check that it is locked by pulling the universal holder.
– Insert a screwdriver bit in the universal holder. Only use
screwdriver bits that fit the screw head.
– To remove the universal holder, slide the locking sleeve
(5) backwards and remove the universal holder (20)
from the tool holder.
