Position for drilling without impact in wood,
metal, ceramic and plastic and for screw-
driving
Vario-Lock position for adjusting the chisel
position
The impact/mode selector switch (12) will
not engage in this position.
Position for chiselling
Setting the Rotational Direction
The rotational direction switch (5) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (7) is being pressed.
Only operate the rotational direction switch (5) when
u
the power tool is not in use.
Always set the rotational direction to clockwise rotation for
hammer drilling, drilling and chiselling.
– Clockwise: Slide the rotational direction switch (5)
all the way to the left.
– Anticlockwise: Slide the rotational direction
switch (5) all the way to the right.
Switching On and Off
– To switch on the power tool, press the on/off switch (7).
The worklight (10) lights up when the on/off switch (7) 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
(7).
Adjusting the Speed/Impact Rate
– Adjust the speed/impact rate of the power tool when it is
on by pressing in the on/off switch (7) to varying extents.
Applying light pressure to the on/off switch (7) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
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 bet-
ter protection than power tools that do
not have KickBack Control. The power
tool will switch off if it suddenly and un-
foreseeably rotates around the drilling
axis.
– To switch the tool back on, release the on/off switch (7)
and then press it again.
Rapid shut-off is indicated by flashing of the worklight (10)
on the power tool.

Practical Advice

Setting the drilling depth (see figure G)
You can use the depth stop (15) to set the required drilling
depth X.
– Press the button for depth stop adjustment (13) and in-
sert the depth stop into the auxiliary handle (14).
The fluting on the depth stop (15) 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.
– 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.
Changing the chiselling position (Vario-Lock)
You can lock the chisel in 44 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 (12) to the "Vario-
Lock" position.
– Turn the application tool to the required chisel position.
– Turn the impact/mode selector switch (12) to the "chis-
elling" position. With this, the tool holder is locked.
– Set the rotational direction for chiselling to clockwise.
Inserting screwdriver bits (see figure H)
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.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
