Only operate the rotational direction switch (8) when
u
the power tool is not in use.
Always set the rotational direction to clockwise rotation for
hammer drilling, drilling and chiselling.
– Clockwise: To drill and to drive in screws, press the
rotational direction switch (8) all the way to the left.
– Left Rotation: To loosen and unscrew screws and
nuts, press the rotational direction switch (8)
through to the right stop.
Note: If the rotational direction switch is in the middle posi-
tion, the on/off switch is blocked.
Switching On/Off
– To switch on the power tool, press the on/off switch
(10).
The worklight (14) lights up when the on/off switch (10) is
lightly or fully pressed, allowing the work area to be illumin-
ated in poor lighting conditions.
When switching on the power tool for the first time, the start
may be slightly delayed as the power tool's electronic system
has to configure itself first.
For low temperatures, the power tool reaches the full ham-
mer/impact capacity only after a certain time.
– To switch off the power tool, release the on/off switch
(10).
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 (10) to varying ex-
tents.
Applying light pressure to the on/off switch (10) 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 36 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 (13) to the "Vario-
Lock" position.
– Turn the application tool to the required chisel position.
– Turn the impact/mode selector switch (13) to the "chis-
elling" position. With this, the tool holder is locked.
– Set the rotational direction for chiselling to clockwise.
Practical Advice
Setting the drilling depth (see figure H)
You can use the depth stop (17) to set the required drilling
depth X.
– Press the button for depth stop adjustment (15) and in-
sert the depth stop into the auxiliary handle (16).
The fluting on the depth stop (17) must face downwards.
– Insert the SDS-plus application tool into the SDS-plus tool
holder (2) 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.
Rapid shut-off (KickBack Control)
The rapid shut-off function (KickBack Control)
gives the user greater control over the power
tool and offers them better protection than
power tools that do not have Kickback Control.
The power tool will switch off if it suddenly and
unforeseeably rotates around the drilling axis.
– To switch the tool back on, release the on/off switch
(10) and then press it again.
Rapid shut-off is indicated by flashing of the worklight (14)
on the power tool.
Vibration damping
The integrated vibration damping function re-
duces the generated vibration.
Do not continue to use the power tool if the damping
u
element is damaged.
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 (22) 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
(4) backwards and remove the universal holder (22)
from the tool holder.
Attaching the Fall Protection System (see figure J)
Note: A fall protection system (24) that is suitable for the
weight of the entire system should be used to prevent the
power tool from falling. The maximum permitted length of
the fall protection system is 1.8 m. Please always refer to the
permitted attachment area (23) on the power tool.
It is best to use the fall protection system with a tape loop se-
cured by an anchor knot or a fall protection system with fall
damper.
Please always refer to the operating instructions when at-
taching the fall protection system (24).
