Putting Into Operation; Working Instructions - Bosch GBH 2-22 RE Bedienungsanleitung

Putting into Operation

Ensure that the mains voltage is correct!
The voltage of the power source must agree with the
value given on the nameplate of the machine. Ma-
chines designated for 230 V can also be operated with
220 V.
Set the Operating Mode
With the operating mode selector switch 7, select the
operating mode of the machine.
Change the operating mode only when the ma-
chine is switched off! Otherwise, the machine can
be damaged.
To change the operating mode, press the locking but-
ton 8 and turn the operating mode selector switch 7 to
the desired position until it can be heard to latch.
For hammer drilling in concrete or stone
and for chiselling.
For drilling in steel or wood, for driving
screws and cutting threads.
Setting the Direction of Rotation (GBH 2-22 RE)
With the right/left rotation switch 4 , the rotational di-
rection of the machine can be changed (see Fig.
Right rotation: Turn the right/left rotation switch 4 on
both sides to position
Left rotation: Turn the right/left rotation switch 4 on
both sides to position
Switching On/Off
To switch on the machine, press the on/off switch 6 .
To lock on , press the on/off switch 6 and lock by
pressing the locking button 5 .
To switch off, release the on/off switch 6. When
locked, first press the on/off switch 6 and then release.
Setting the Speed (GBH 2-22 E/GBH 2-22 RE)
By increasing or decreasing the pressure on the on/off
switch 6, the speed of the switched-on machine can
be continuously regulated.
Reduced speed of the machine facilitates the starting
of holes (e.g., on smooth surfaces such as tiles), pre-
vents the slipping of the drill and the splintering of the
drilled hole.
Recommended Speed Ranges:
– High speed for hammer drilling in concrete or stone
as well as for chiselling
– High speed for drilling in steel
– Medium speed for drilling in wood
– Low speed for driving screws and cutting threads.
