Run-on Brake
When the On/Off switch 9 is released, the chuck
brakes to a stop, thus preventing the run-on of
the tool.
When driving in screws, wait until the screw is
screwed in flush with the material and then re-
lease the On/Off switch 9. By doing so, the head
of the screw does not penetrate into the materi-
al.
Overload 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.
Operating Instructions
Do not operate the power tool stationary. It
is not designed for operation in a drill stand.
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.
The machine is also suitable for occasional
screwdriving jobs, however, not for screwdriv-
ing applications with intense speed reductions
where the safety clutch disengages frequently.
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.
1 619 929 757 | (2.8.07)
Insert a screwdriver bit into the universal bit
holder. Use only screwdriver bits that match the
screw head.
Set the selector switch 7 to the "Drilling" sym-
bol.
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 (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
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 serv-
ice.
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.
