Applying light pressure to the on/off switch (9) 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.
Practical Advice
Setting the drilling depth (see figure F)
You can use the depth stop (15) to set the required drilling
depth X.
– Press the button for depth stop adjustment (5) and insert
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 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 (7) to the "Vario-
Lock" position.
– Turn the application tool to the required chisel position.
– Turn the impact/mode selector switch (7) 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 G)
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 (18) 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 (18)
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.
Maintenance and Service
Maintenance and Cleaning
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.
