Method Of Operation; Changing The Tool - Bosch PROFESSIONAL GDR 9,6 V Instructions D'emploi

The battery is equipped with an NTC temperature
control which allows charging only within a tem-
perature range of between 0 °C and 45 °C.
A long battery service life is achieved in this man-
ner.
A significantly reduced working period after
charging indicates that the batteries are used and
must be replaced.
Observe the notes on environmental protec-
tion.

Method of Operation

The tool holder 1 with the tool is driven by an
electric motor via a gear and impact mechanism.
The working procedure
two phases:
Screwing in and tightening (impact mechanism
in action)
The impact mechanism is activated as soon as
the screwed connection runs tight and load is put
on the motor. In this instance the impact mecha-
nism converts the power of the motor to steady
rotary impacts. When loosening screws, the proc-
ess is reversed.

Swivel Lighting System (see figure
A light source is integrated in the knurled thumb-
wheel 8. The lamp is activated as soon as the
On/Off switch 10 is pressed, unless the knurled
thumbwheel is in the position 0.
The setting of the light beam can be adjusted in
3 steps, depending on the tool insert being used.
In position 1 the focus of the light beam is approx.
20 mm, in position 2 approx. 150 mm and in po-
sition 3 approx. 500 mm in front of the tool
holder 1.
In position 0 the lamp is switched off perma-
nently.
Belt clip (see figure
With the belt clip 5 the machine can be hung,
e. g., to a hook. This allows for both hands to be
free while the machine is ready to hand.
The belt clip 5 can be screwed to the machine on
either side.
