Reversing the Rotational Direction
The rotational direction switch 4 is used to reverse the
rotational direction of the machine. However, this is
not possible with the On/Off switch 6 actuated.
Right rotation: Turn the selector switch for drill-
ing/hammer drilling 4 on both sides to the stop in
the position
.
Left rotation: Turn the selector switch for drill-
ing/hammer drilling 4 on both sides to the stop in
the position
.
Set the direction of rotation for hammer drilling, drilling
and chiselling always to right rotation.
Switching On and Off
To start the machine, press the On/Off switch 6.
To lock the On/Off switch, keep it pressed and addi-
tionally push the lock-on button 5.
To switch off the machine, release the On/Off switch
6. When the On/Off switch 6 is locked, press it first
and then release it.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on power tool
can be variably adjusted, depending on how far the
On/Off switch 6 is pressed.
Light pressure on the On/Off switch 6 results in low
speed/impact rate. Further pressure on the switch
increases the speed/impact rate.
Overload Clutch
If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted.
Because of the forces that occur, always
hold the power tool firmly with both hands
and provide for a secure stance.
If the power tool jams, switch the machine
off and loosen the tool insert. When switch-
ing the machine on with the drilling tool
jammed, high reaction torques can occur.
Operating Instructions
Chiselling
For chiselling, a MV 200 SDS-plus chiselling attach-
ment (accessory), which is inserted into the SDS-plus
tool holder 1, is required.

Inserting Screwdriver Bits (see figure H)
Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts can
slip off.
To work with screwdriver bits, a universal bit holder 21
with SDS-plus shank (accessory) is required.
Clean the shank end of the adapter shank and apply a
light coat of grease.
Insert the universal bit holder with a turning motion
into the tool holder until it automatically locks.
Check the locking effect by pulling the universal bit
holder.
Insert a screwdriver bit into the universal bit holder.
Use only screwdriver bits that match the screw head.
To remove the universal bit holder, pull the locking
sleeve 3 toward the rear and remove the universal bit
holder 21 out of the tool holder.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales service.
Clean the tool holder 1 each time after using.
WARNING! Important instructions for connect-
ing a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to the
following code:
Do not connect the blue or brown wire to the earth
terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it must be
disposed of safely.
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service centre for
Bosch power tools.
In all correspondence and spare parts order, please
always include the 10-digit article number given on
