Initial Operation - Bosch GSB 22-2 RE Bedienungsanleitung

Initial Operation

Do not drill, fasten or cut into blind areas
where electric, gas or water lines may exist.
Use appropriate detectors to determine if
these lines are hidden in the work area or
call the local utility company for assis-
tance.
Contacting electric lines may cause fire or
electric shock. Striking a gas line will probably
result in explosion. Breaking into a water pipe
will cause property damage or may cause an
electric shock.
Check for correct mains voltage: The voltage
of the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching on and off
Brief activation
Press or release the On/Off switch 6.
Continuous use
Switching on: Press On/Off switch 6 and
retain with locking button 5.
Switching off: Press and release On/Off
switch 6.
Changing the Rotational Directions
Operate the
switch 7 only at a standstill.
Using the rotational direction switch 7, the direc-
tion of rotation of the machine can be changed
(by actuating the On/Off switch 6, the rotational
direction switch 7 can be locked).
Right Rotation (see figure
Press the rotational direction switch through to
the right stop (for drilling, impact drilling, driving
screws, etc.).
Left Rotation (see figure
Press the rotational direction switch through to
the left stop (for loosening and unscrewing
screws and nuts).

Gear selector, mechanical
Two speed ranges can be preselected with the
gear selector 8:
Speed I: Lower rpm range
Speed II: Higher rpm range
The gears can be switched when the machine is
running or at standstill. However, this should not
be carried out at full load or maximum speed.
Stepless Speed Control
The machine runs with variable
speed between 0 and maximum
depending on the pressure applied
to the On/Off switch 6.
Light pressure results in a low rotational speed
thus allowing smooth, controlled starts.
Do not load the machine so heavily that it comes
to a standstill.
Speed Selection
With the thumbwheel 3, the required speed can
be selected (also while running).
The required speed is dependent on the material
and can be determined by trial and error.
After longer periods of working at low speed, al-
low the machine to cool down by running for ap-
prox. 3 minutes at maximum speed with no load.
Constant Electronics (GSB 22-2 RCE)
The Constant Electronics with "Tachogenerator"
keep the set speed almost constant, even under
load.
Drilling, Driving and Impact Drilling
Drilling and Driving
Push selector switch 2 to the right.
Impact Drilling
Push selector switch 2 to the left.
The switch 2 notches in distinctly and can be op-
erated whilst the machine is running. Hard metal
drills are necessary when working with concrete,
stone and brick.
