Practical Advice

Setting the drilling depth (see figure J)
You can use the depth stop (11) to set the required drilling
depth X.
– Press the button for depth stop adjustment (10) and in-
sert the depth stop into the auxiliary handle (12).
The fluting on the depth stop (11) 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.
– 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 K)
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 (23) 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 (23)
from the tool holder.

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.

needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch

It is recommended that you have use an after-sales
