Safety Clutch
If the tool insert becomes caught or
jammed, the drive to the drill spindle is in-
terrupted. 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.

Working Advice

Chiselling
For chiselling, a MV 200 SDS-plus chiselling at-
tachment (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 re-
quired.
Clean the shank end of the adapter shank and
apply a light coat of grease.
Insert the universal bit holder with a turning mo-
tion 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 lock-
ing sleeve 3 toward the rear and remove the uni-
versal 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
having this carried out by an after-sales
service.
Clean the tool holder 1 each time after using.
WARNING! Important instructions for con-
necting 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 the type plate of the machine.
