Switching Off

Release the On/Off switch 

1

. When the On/Off switch 

1

 is 

locked, press the On/Off switch first and then release.

Wet drilling: Shut the water cock 

9

. After finishing work, dis-

connect the water outlet connector 

8

 from the water supply. 

Open the water cock 

9

 and drain the remaining water.

Reduced starting current

The electronics of the power tool make the motor start softly, 
therefore preventing the starting current from being too high.

Restarting Protection

The restarting protection feature prevents uncontrolled 
restarting of the machine after an interruption in the power 
supply.

To 

restart

, press the 

“RESET”

 button on the portable residu-

al current device (PRCD) 

3

. Then switch the On/Off switch 

1

to the off-position and switch the power tool on again.

Preselecting the Speed

Two speeds can be preselected using the gear selector 

10

.

The gears are recommended for the following drilling diame-
ters:

Working Advice



Before any work on the machine itself, pull the mains 

plug.

Always use a centring cross (accessory) when starting the 
drilling procedure without the use of a drill stand.

Start drilling in 1st gear at low speed until the core bit rotates 
vibration-free in the material. Afterwards switch to the 2nd 
gear, if required.

While drilling, adapt the feed pressure to the material being 
drilled. Drill with uniform pressure. Lightly pull the core bit 
out of the bore from time to time so that the drilling sludge or 
drilling dust can be removed from the core bit segments.

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.

Overload Protection

If the overload threshold is exceeded, then the power tool will 
begin to pulsate noticeably. Reduce the feed pressure until 
the power tool works normally again.

If the feed pressure is not reduced, then the power tool will 
switch off. You can then switch the power tool back on 
straightaway, but you should continue to work with reduced 
feed pressure.

Removing the Core

Wet drilling: 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 screw-
driver or similar).

Note: 

Do not hammer or apply blows onto the core bit with 

hard objects (danger of deformation)!

Maintenance and Service

Maintenance and Cleaning



Before any work on the machine itself, pull the mains 

plug.



For safe and proper working, always keep the machine 

and ventilation slots clean.

Clean the drilling spindle 

15

 after finishing work. Occasionally 

spray an anti-corrosion agent onto the drilling spindle and the 
core bit 

14

.

If the replacement of the supply cord is necessary, this has to 
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
