Maintenance And Service; Maintenance And Cleaning; Accessories/Spare Parts - Bosch GDB 1600 WE Operating Instructions Manual

Overload Clutch
If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted.
Because of the forces that occur, always hold
the power tool firmly with both hands and
provide for a secure stance.
Control Indicator
The control indicator 1 flashes:
The power tool is operating in the
overload range.
Reduce the feed pressure. If
required, switch the machine off
and sharpen the core bit.
When the feed pressure is not
reduced, the electronic control
will reduce the speed. In case of continued overload,
the power tool switches off. Free the load on the power
tool and switch on again.
The control indicator 1 lights up
continuously:
The carbon brushes must be
replaced.
A Bosch after-sales service sta-
tion will handle this maintenance
task quickly and reliably.
Removing the Core
GDB 1600 WE with flusing head 6: After drilling, con-
tinue to run the water for a short period in order to flush
out the drilling sludge between the core bit and the
core.
If the drilling core is stuck in the core bit, then apply
light blows onto the core bit with a piece of soft wood
or plastic in order to loosen the core. If required, pry the
drilling core out of the core bit using an appropriate
hand tool (slotted screwdriver or similar).
Note: Do not hammer or apply blows onto the core bit
with hard objects (danger of deformation)!

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep the

ufacturing and testing procedures, repair should be
carried out by an after-sales service centre for Bosch
power tools.
