and clamp the tool uniformly.
Screwdriver Tools (see figure C)
When working with screwdriver bits
11
, a universal bit holder
12
should always be used. Use only screwdriver bits that fit
the screw head.
Replacing the Drill Chuck
For machines without spindle lock, the drill chuck must be re-
placed through an authorized 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 mate-
rials 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)
(see figure D)
The rotational direction switch
8
is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch
7
actuated.
Right Rotation:
For drilling and driving in screws, push the
rotational direction switch
8
left to the stop.
Left Rotation:
For loosening and unscrewing screws and
nuts, press the rotational direction switch
8
through to the
right stop.
Switching On and Off
To
start
the machine, press the On/Off switch
7
and keep it
pressed.
To lock the
pressed
On/Off switch
7
, press the lock-on button
6
.
To
switch off
the machine, release the On/Off switch
7
or
when it is locked with the lock-on button
6
, briefly press the
On/Off switch
7
and then release it.
Adjusting the Speed (GBM 10 RE)
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch
7
is pressed.
Light pressure on the On/Off switch
7
results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
