Bosch GSH 3 E PROFESSIONAL Bedienungsanleitung Seite 9

Use appropriate detectors to determine if
utility lines are hidden in the work area or
call the local utility company for assist-
ance.
Contact with electric lines can lead to fire and
electric shock. Damaging a gas line can lead
to explosion. Penetrating a water line causes
property damage or may cause an electric
shock.
Hold the power tool only by the insulated
handles, when performing an operation
where the tool insert can run into hidden
wiring or its own mains cable. Contact with
a "live" wire can make metal parts of the power
tool "live" and lead to an electric shock.
Auxiliary Handle
Operate the machine only with the auxiliary
handle 6.
Loosen the handle by turning to the left. Rotate
the auxiliary handle 6 and adapt to the working
position.
Afterwards tighten the handle again by turn-
ing in clockwise direction.
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.

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 locks. Check if it has locked by pull-
ing the tool.
Removing (see figure
Push back the locking sleeve 2 of the tool holder
and remove the tool. Let go of the locking
sleeve 2 again.
Starting Operation
Observe correct mains voltage: The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching On and Off
To start the machine, press the On/Off switch 5
and keep it depressed.
Lock the pushed On/Off switch 5 by pressing the
lock-on button 4.
To switch off the machine, release the On/Off
switch 5 or push and release it then.
At low temperatures, the machine reaches
full impact rate only after a certain time.
This start-up time can be shortened by
striking the chisel against the floor once.
Changing the Impact Rate
With the On/Off switch 5, the impact frequency
can be changed between low and high impact.
Applying slight pressure on the On /Off switch 5
leads to low impact frequency. With increasing
pressure, the impact frequency increases.
