Bosch Power Tools
Assembly
Changing the Tool
Before any work on the machine itself, pull the mains
plug.
Wear protective gloves when changing the tool.
The
drill chuck can become very hot during longer work peri-
ods.
Key Type Drill Chuck (see figure A)
Open the key type drill chuck
1
by turning until the tool can be
inserted. Insert the tool.
Insert the chuck key
7
into the corresponding holes of the key
type drill chuck
1
and clamp the tool uniformly.
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 tighten-
ing 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 10 RE,
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.
When not using the power tool, switch it off in order to save
energy.
Adjusting the Speed (GBM 10 RE, 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
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).
We recommend the use of a drill stand (see accessories) for
work where greater precision is particularly required.
The machine vice, which is available as an accessory, enables
secure clamping of workpieces. This prevents the workpiece
from turning and any accidents this would cause.
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.
