Control Indicator
The control indicator 12
flashes:
The power tool is operating
in the overload range.
Reduce the feed pressure. If
required, switch the ma-
chine off and sharpen the
core bit.
When the feed pressure is not reduced, the elec-
tronic control will reduce the speed, even to a
complete stop, if required. After the load is
freed, the machine automatically restarts again.
The control indicator 12
lights up continuously:
The carbon brushes must be
replaced.
A Bosch after-sales service
station will handle this main-
tenance task quickly and re-
liably.
Removing the Core
After drilling, continue 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 deforma-
tion)!
