Screwdriver Tools (see figure B)
When working with screwdriver bits 8, a universal bit holder 9
should always be used. Use only screwdriver bits that fit the
screw head.
Replacing the Drill Chuck
For power tools without spindle lock, the drill chuck must
be replaced by an authorised after-sales service agent for
Bosch power tools.
The drill chuck must be tightened with a tightening
torque of approx. 31–35 Nm.
Dust/Chip Extraction
 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er 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.
Reversing the rotational direction (GBM 13 RE)
(see figure C)
The rotational direction switch 6 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 5 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 6 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 6 through to the
right stop.
Switching On and Off
To start the machine, press the On/Off switch 5 and keep it
pressed.
To lock the pressed On/Off switch 5, press the lock-on button
4.
To switch off the machine, release the On/Off switch 5 or
when it is locked with the lock-on button 4, briefly press the
On/Off switch 5 and then release it.

Adjusting the Speed (GBM 13 RE)
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 5 is pressed.
Light pressure on the On/Off switch 5 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Working Advice
 Before any work on the machine itself, pull the mains
plug.
 Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is guar-
anteed by the Bosch accessories program.
Twist drills from 2.5-10 mm can easily be sharpened with the
drill bit sharpener (see accessories).
Belt Clip
With the belt clip 2, the machine can be hung onto a belt. The
user has both hands free and the machine is always at hand.
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.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
If the machine should fail despite the care taken in manufac-
turing 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 in-
clude the 10-digit article number given on the type plate of
the machine.
