Maintenance And Cleaning - Bosch GBH 24 V Operating Instructions Manual

Impact Stop Switch
Operate the impact stop switch 5 only
when at a standstill.
Set the impact stop switch 5 to the desired posi-
tion:
Drilling
Hammer drilling
Run-On Brake
When releasing the On/Off switch 6 the speed of
the drill chuck is reduced to a stop, thus prevent-
ing the run-on of the tool.
Any sparking occurring during this process in the
area of the upper ventilation slots is normal and
does not damage the machine.
For screwdriving applications, wait until the screw
is flush with the material and then release the
On/Off switch 6. The screw head does not pene-
trate into the material then.
Drill Bits with
Cylindrical Shanks
Tool inserts with cylindrical shank can be
clamped with the key type drill chuck (accessory)
and the corresponding adapter (accessory).
Set the impact stop switch 5 to "Drill-
ing" (only at a standstill).
Clean and lightly grease the adapter shank.
Insert the assembled chuck with a twisting man-
ner into the tool holder until it latches. The chuck
locks itself. Check the locking by pulling on the
chuck.

Screwdriving (see figure
The machine is also suitable for occasional
screwdriving applications, however, not for
screwdriving applications with extreme re-
ductions of speed at which the overload
clutch frequently responds.
For screwdriving, the universal bit holder with
SDS-plus shank (accessory) must be used.
– Set the impact stop switch 5 to "Drill".
– Set the direction of rotation to right-hand rota-
tion.
– Regulate the speed with the On/Off switch 6.

Maintenance and Cleaning

Before any work on the machine itself, re-
move the battery.
For safe and proper working, always keep
the machine and the ventilation slots clean.
Keep the tool holder clean at all times.
The inserted battery 8 must always be seated
flush on the machine. In case the locking
latches 12 of the machine or the battery are dam-
aged, machine or battery may not be used fur-
ther. Moreover, they are to be sent to an author-
ized service centre for Bosch power tools. (see

Changing the Dust Protection Cap
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit order number
given on the nameplate of the machine.
