For Your Safety; Putting Into Operation - Bosch GBH 2-24 DS Operating Instructions Manual

For Your Safety

Working safely with this machine is
possible only when the operating
and safety information are read
completely and the instructions
contained therein are strictly fol-
lowed.
In addition, the general safety
notes in the enclosed booklet must
be observed.
Before using for the first time, ask
for a practical demonstration.
Wear ear protection to prevent damage
to your hearing.
Wear safety glasses.
For long hair, wear hair protection.
Work only with close-fitting clothes.
If the cable is damaged or cut through while work-
s
ing, do not touch the cable but immediately pull the
mains plug. Never use the machine with a dam-
aged cable.
Connect machines that are used outdoors by
s
means of a fault current protection switch (FI) with
a maximum triggering current of 30 mA. Use only
an extension cable that is approved for outdoor
use.
Always direct the cable to the rear away from the
s
machine.
Use suitable detectors to find hidden utility
s
lines or call the local utility company for as-
sistance. Contact with electric lines can lead to
fire or electrical shock. Damaging a gas line can re-
sult in an explosion. Penetrating a water pipe will
cause property damage or an electrical shock.
Operate the machine only with the auxiliary handle
s
9 .
Secure the workpiece. A workpiece clamped
s
with clamping devices or in a vice is held more se-
cure than by hand.
Place the machine on the nut/screw only when
s
switched off.
For screwdriving, work using the first gear or with a
s
low speed.
Be careful when screwing in long screws; danger
s
of sliding off.
When working with the machine, always hold it
s
firmly with both hands and provide for a secure
stance.
Always switch the machine off and wait until it has
s
come to a standstill before placing it down.
Never allow children to use the machine.
s
Bosch is able to ensure flawless functioning of the
s
machine only if the original accessories intended
for it are used.

Tool Changing (Fig. M–Q)
Take care that the dust protection cap 2 is not
damaged when changing tools.
SDS-Plus Tools
The SDS-plus tool is designed to be freely movable.
This causes eccentricity when the machine is off-load.
However, the drill automatically centres itself during
operation. This does not affect drilling precision.
Inserting (Fig.
Clean and lightly oil the tool before inserting.
Insert the dust-free tool into the tool holder 1 with
twisting until it latches.
The tool locks itself. Check the locking by pulling on
the tool.
Removing (Fig.
Pull the locking sleeve 3 to the rear (a) and hold while
removing the tool (b) .
Tools without SDS-plus
Do not use tools without SDS-plus for hammer
drilling or chiselling!
To work with tools without SDS-plus (e.g., drills with
cylindrical shafts), a drill chuck 11 with a SDS-plus
chuck shaft 12 (optional accessory) must be inserted
into the tool holder (Fig.
Insert the dust-free, assembled chuck into the tool
holder 1 with twisting until it latches (Fig.
The chuck locks itself. Check the locking by pulling on
the chuck.
Srewdriver Bits (Fig.
For screwdriver bits, use the SDS-plus adapter 13 (op-
tional accessory).
System Accessories
Refer to the Bosch Catalogue for insertion tools.
A list of accessories can be found at the end of these
instructions.
