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

f 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.

f 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

f Do not operate the power tool stationary. It

is not designed for operation in a drill stand.

Inserting Screwdriver Bits (see figure H)

f 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.

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

f 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.

f For safe and proper working, always keep

the machine and ventilation slots clean.

f 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.
