For Your Safety; Inserting The Tool - Bosch GSB 20-2 Operating Instructions Manual

For Your Safety

Working safely with this ma-
chine is possible only when the
operating and safety information
are read completely and the in-
structions contained therein are
strictly followed. In addition, the
general safety notes in the en-
closed booklet must be ob-
served. Before using for the first
time, ask for a practical demon-
stration.
If the mains cable is damaged or
cut through while working, do not
touch the cable but immediately
pull the mains plug. Never use the
machine with a damaged cable.
Wear protective glasses and hear-
ing protection.
For long hair, wear hair protection.
Work only with closely fitting
clothes.
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.
Insert the mains plug only when the machine is
switched off.
Always direct the cable to the rear away from
the machine.
When drilling use the auxiliary handle 13.
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.
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.

If the drilling tool jams, it will cause the power
tool to jolt. If this occurs switch the tool off im-
mediately.
When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
Be careful when screwing in long screws; dan-
ger of sliding off.
When screwdriving, operate in first gear as
well as with a low speed.
Set the machine against the screw /nut only
when switched 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 is only able to ensure perfect operation
of the machine if the original accessories in-
tended for it are used.
Auxiliary Handle/Depth Stop
The auxiliary handle can be mounted on the left
or right side of the spindle collar, using the
winged screw 12.
The drilling depth can be set with the depth
stop 14. For this, loosen wing bolt for depth stop
adjustment 11, set the required drilling depth X
and tighten the wing bolt again.

Inserting the Tool

Open the drill chuck until the tool can be inserted.
Insert the tool.
Keyless Chuck
Hold the rear collar tight and firmly tighten the
front collar by hand, until the "clicking" of the lock-
ing action is no longer heard. This automatically
locks the chuck.
The locking is released again when the front col-
lar is turned in the opposite direction to remove
the tool.
Caution! The chuck may be very hot:
During longer working periods, especially
when impact drilling, the chuck can become
very hot. In this case we recommend wearing
protective gloves.
