Operation
Starting Operation
Observe correct mains voltage! The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Power tools marked with 230 V can also be
operated with 220 V.
Setting the Operating Mode
With the selector switch for drilling/hammer drilling 4,
the operating mode of the machine is selected.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine can
be damaged.
To change the operating mode, press the release but-
ton 5 and turn the drilling/hammer drilling selector
switch 4 to the desired position until it can be heard to
latch.
Position for hammer drilling in concrete
or stone as well as for chiselling (chiselling
only with the MV 200 accessory).
Position for drilling without impact in
wood, metal, ceramic and plastic as well
as for screwdriving and thread cutting.
Reversing the Rotational Direction
The rotational direction switch 6 is used to reverse the
rotational direction of the machine.
Actuate the rotational direction switch 6 only
when the machine is at a standstill.
Right rotation: Turn the selector switch for drill-
ing/hammer drilling 6 on both sides to the stop in
the position
.
Left rotation: Turn the selector switch for drill-
ing/hammer drilling 6 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 8.
To lock the On/Off switch, keep it pressed and addi-
tionally push the lock-on button 7.
To switch off the machine, release the On/Off switch
8. When the On/Off switch 8 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 8 is pressed.
Light pressure on the On/Off switch 8 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 switching
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.
The dust extraction 14 may not be mounted for chisel-
ling.
Inserting Screwdriver Bits (see figure M)
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 31
with SDS-plus shank (accessory) is required.
The dust extraction 14 may not be mounted for screw-
driving.
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 31 out of the tool holder.
