Vario-Lock position for changing the chiselling
position.
The impact/mode selector switch (12) will not
engage in this position.
Position for chiselling
Setting the Rotational Direction
Only operate the rotational direction switch (5) when
u
the power tool is not in use.
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.
Right rotation: Slide the rotational direction switch
(5) all the way to the left.
Left rotation: Slide the rotational direction switch
(5) all the way to the right.
Always set the rotational direction to right rotation for ham-
mer drilling, drilling and chiselling.
Rotational direction switch in centre position: Set the ro-
tational direction switch (5) to the centre position to protect
the power tool from being switched on accidentally.
Switching On/Off
– To switch on the power tool, press the on/off switch (7).
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.
– To switch off, release the on/off switch (7).
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 (7) to varying ex-
tents.
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 better
protection than power tools that do not have KickBack Con-
trol. The power tool will switch off if it suddenly and unfore-
seeably rotates around the drilling axis.
– To switch the tool back on, release the on/off switch 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 I)
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 positions. This makes it pos-
sible for you to always work in the ideal position.
– Insert the chisel into the tool holder.
– Turn the impact/mode selector switch (12) to the "Vario-
Lock" position Setting the Operating Mode.
– Turn the application tool to the required chiselling posi-
tion.
– Turn the impact/mode selector switch (12) to the "chis-
elling" position. With this, the tool holder is locked.
– Set the rotational direction to right rotation for chiselling.
Inserting screwdriver bits (see figure J)
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.
Only store the battery within a temperature range of –20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
