Bosch GBH 2-24 DS Operating Instructions Manual page 10

Wear protective glasses and ear
protection.
For long hair, wear hair protection.
Work only with closely fitting
clothes.
Do not drill, cut or saw into blind areas
where electric, gas or water lines may exist.
Use suitable detectors to determine if these
lines are hidden in the work area or call the
local utility company for assistance.
Contact with electric lines may cause fire or
electric shock. Damaging a gas line can result
in an explosion. Penetrating a water pipe will
cause property damage or may cause an elec-
tric shock.
Hold the power tool only by the insulated
gripping surfaces, when performing an op-
eration where the cutting tool may run into
hidden wiring or its own cord.
Contact with a "live" wire will make exposed
metal parts of the tool "live" and shock the op-
erator.
Connect machines that are used in the open
via a residual current device (RCD) with an ac-
tuating current of 30 mA maximum. Use only
extension cables that are approved for outdoor
use.
Use the machine only with the auxiliary han-
dle 8.
Always direct the cable to the rear away from
the machine.
Do not carry or hang up the machine by the ca-
ble.
Insert the mains plug only when the machine is
switched off.
Set the machine against the screw /nut only
when switched off.
When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
When screwdriving, operate in first gear as
well as with a low speed.
Be careful when screwing in long screws; dan-
ger of sliding off.
Always switch off the machine and allow to
come to a stop before placing it down.
Never allow children to use the machine.
Bosch can only ensure perfect operation of the
machine, if the original accessories intended
for it are used.

Changing the Tool
Before any work on the machine itself, pull
the mains plug.
With the SDS-plus tool holder, simpler and easier
tool changing is possible without additional aids.
Grease the shank end of the tool regu-
larly.
The dust protection cap 1 largely prevents the
entry of drilling dust during operation. When in-
serting the tool, take care that the dust protection
cap 1 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
It is a requirement of the system that the
SDS-plus tool rotates freely, thereby pro-
ducing a radial eccentricity when the ma-
chine is running at no-load speed.
This does not affect the accuracy of the drill
hole, as the bit is automatically centred dur-
ing drilling.
Inserting (see figure
Clean and grease the shank end of the tool.
Insert the tool in a twisting manner into the tool
holder until it latches itself. Check the latching by
pulling on the tool.
Removing (see figure
Push back the locking sleeve 2 of the tool holder
and remove the tool.
Auxiliary Handle/Depth Stop
Use the machine only with the auxiliary
handle 8.
Loosen the handle by turning to the left. Rotate
the auxiliary handle 8 and adapt to the working
position.
Firmly retighten the handle.
The drilling depth can be set with the depth
stop 9.
The ribbing on depth stop 9 must point upwards.
