Control Indicator

The control indicator

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 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)!
