Setting the Direction of Rotation GBH 2-24 DSR
With the right/left rotation switch
10
, the rotational
direction of the machine can be changed.
Change the direction of rotation only when the
machine is switched off!
Otherwise, the machine
can be damaged.
Right rotation:
Press the right/left switch
10
to the right to the stop.
Left rotation:
Press the right/left switch
10
to the left to the stop.
Set the direction of rotation for hammer drilling and
drilling always for right rotation.

Setting the chisel position (VARIO-LOCK)
The percussion drill (GBH 2-24 DSE /
DSR) is suitable for light-duty chiseling
work. Operator fatigue can be avoided by
rotating the tool (e.g. flat chisel) to the
optimum position for use. The tool mount
can be set to 36 different positions.
Always wear protective gloves!
Insert the tool into the tool mount.
Press release button
6
and turn the mode selector
switch
7
to Chisel adjustment. (Fig.
L
) When the
mode selector switch is in the Vario-lock position, the
tool mount can be rotated to the desired position.
To fix the tool mount in position, turn the mode
selector switch until it engages in the Chiseling
setting.
Always set the mode selector switch
7
to
Chiseling when carrying out chiseling.
Overload clutch
If the drill becomes caught or jammed, the drive to
the drill spindle is interrupted.
Because of the forces that occur as a result, always
hold the machine securely with both hands and take
a firm stance.
Sharpening chisels
Since good results can only be achieved using sharp
chisels, it is important to sharpen tools in good time.
This prolongs the life drilling depth. As a result the
vacuum attachment head always of your tools and
ensures high efficiency.
Grind chisels using grinding wheels (e.g. corundum).
Keeping the chisels wet using a steady supply of
water. Refer to the drawings below for recommended
values. Make sure that no annealing colour appears
on the cutting edges, otherwise the hardness of the
chisel will be impaired (Fig.
R
,
S
,
T
).
Dust extraction
Dust extraction prevents large accumulations of dust,
high concentrations of dust in the ambient air and
facilitates disposal.
The appliance can be plugged directly into the
socket of a Bosch all-purpose vacuum cleaner which
incorporates a
remote control Saugfix start
device.
Attach vacuum attachment (accessory) and connect
the vacuum cleaner. The vacuum attachment springs
back as far as the preset drilling depth. As a result
the vacuum attachment head always remains close
to the surface.
Maintenance and cleaning
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep
the machine and the ventilation slots clean.
Clean the tool holder daily.
Replacing the Dust Protection Cap
Replace the dust protection cap
1
without delay if it
is damaged. A damaged dust protection cap can
allow dust to penetrate into the tool holder and lead
to malfunctions.
Have the replacement of the dust protection cap
performed by a customer service agent.
In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The
protective insulation of the machine can be
de-graded. The use of a stationary extraction
