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 (9) to varying ex-

Practical Advice

Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
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.
Chiselling
For chiselling, you will need an SDS plus chisel MV 200 at-
tachment (accessory), which inserts into the SDS plus tool
holder (2).
The dust extraction system (15) must not be mounted when
chiselling.
Inserting screwdriver bits (see figure M)
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 (33) 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.

Maintenance and Cleaning

position.
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.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.

u
It is recommended that you have use an after-sales
service for this.
– Clean the tool holder (2) after each use.
Changing the Filter Element (see figure N)
In order to maintain the filter performance, the filter
element (25) of the dust box (10) must be changed after ap-
prox. 15 operating hours.
– To remove the dust box (10), press the two release
buttons (12) and pull the dust box downward out of the
dust extraction system (15).
– Remove the filter element (25) upward and insert a new
filter element.
– Reinsert the dust box into the dust extraction
system (15) from below until you hear it click into place.
Note: If the filter element (25) is damaged (e.g. holes, dam-
age to the soft sealing material), it must be replaced immedi-
ately. Working with a damaged filter element can cause dam-
age to the power tool.
Also replace the filter element (25) when the suction capa-
city is insufficient, even when the dust box (10) is empty.
