Bosch Power Tools

– Briefly and quickly press the On/Off switch 

13

.

The machine and the display are switched off immediately.

Note:

 The power tool is now currentless. All current set-

tings are deleted.

– To restart the operation of the machine afterwards, the 

On/Off switch 

13

 must be reset to position “

0

”.

Afterwards, the machine can be switched on again (On/Off 
switch 

13

 in position

).

Restarting Protection

The restarting protection prevents uncontrolled starting of 
the machine after a power failure (e.g., when the mains plug is 
pulled during operation).

– To restart the operation of the machine afterwards, the 

On/Off switch 

13

 must be reset to position 

.

Afterwards, the machine can be switched on again (On/Off 
switch 

13

 in position

).

Temperature Dependent Overload Protection

When using the machine as intended for, it cannot be subject 
to overload. In case of excessive loading or when exceeding 
the allowable operating temperature, the electronics switch 
the machine off until it is in the optimal operating-tempera-
ture range again.

– To restart the operation of the machine afterwards, the 

On/Off switch 

13

 must be reset to position 

.

Afterwards, the machine can be switched on again (On/Off 
switch 

13

 in position

).

Adjusting the Speed



Set the correct speed before beginning to work. The 
speed must be appropriate for the drilling diameter 
and the material being drilled. 

When the speed is set in-

correctly, the application tool can become caught or jam in 
the workpiece.

When adjusting the appropriate speed, please refer to the 
speed diagram 

6

.

The diagram provides the speed (

rpm

) to be set dependent 

on the drill bit diameter (

Ø

in mm) for the materials 

Steel

 and 

Aluminium

.

Gear selection, mechanical
Actuate the gear selector 21 only when the machine is at 
a standstill.

Two speed ranges can be preselected with the gear selector 

21

.

1st gear:

Low speed range; for working with large drilling diameters.

2nd gear:

High speed range; For working with small drilling diameters.

– Set the gear selector 

21

 to the desired position.

Note: 

If the gear selector 

21

 cannot be turned to the stop, 

turn the drill chuck a little.

Electronic Speed Control (see figure H)

With the speed regulator 

15

, the speed of the machine can be 

variably adjusted.

– To 

start the machine

, turn the On/Off switch 

13

 to 

position

.

– Press button 

32

 until “

Speed

” is indicated on the display.

– Turn the speed regulator 

15

 until the desired speed is indi-

cated on display 

14

.

Working Advice

General Information

Before drilling, make sure that the quick-clamping device 

3

, 

the parallel guide 

19

 or the machine vice (accessory) are firm-

ly clamped/tightened.

When the drill bit comes out of the workpiece, it can become 
caught or jam in the workpiece, and drag the workpiece along. 
Therefore, reduce the feed at the end of the drilling phase.

If the application tool should become blocked, switch the ma-
chine off. Allow the application tool and the workpiece to cool 
down. Remove the drilling chips/swarf. Determine the cause 
of the application tool's jam and correct it.

Special Notes on Drilling in Metal

Centre-punch metal workpieces.

Pilot-drill when drilling diameters in excess of 10 mm.

To improve your work, use cutting oil (e.g. Bosch universal 
cutting oil) to cool the drilling.

Position of the Operator



Position yourself in front of the machine. 

This ensures a 

good view of the drilling location.

– Keep your hands and fingers away from the rotating appli-

cation tool.

– Do not stand in front of the motor unit with crossed arms.

Drilling

– Place the workpiece on base plate 

1

.

– Adjust the height of the motor unit (see “Adjusting the 

Height of the Motor Unit”, page 21).

– Align the workpiece with help of the laser cross (see “Cor-

rectly positioning the workpiece”, page 21).

– Firmly clamp the workpiece (see “Clamping the Work-

piece”, page 21).

– Adjust the appropriate speed (see “Adjusting the Speed”, 

page 22).

– Switch on the machine.
– For drilling, turn handwheel 

11

 with uniform feed until the 

desired drilling depth is reached (see “Indicating the Drill-
ing Depth”, page 22).

– Once the desired drilling depth is reached, guide hand-

wheel 

11

 back until the motor unit is back in the starting 

position.

– Switch the power tool off.

Indicating the Drilling Depth (see figure I)

The current drilling depth can be indicated on the display 

14

.

– After the speed has been set, press button 

32

 until 

“

Depth

” is indicated on the display.

– Adjust the height of the motor unit (see “Adjusting the 

Height of the Motor Unit”, page 21).

– Carefully allow the drill-bit tip to slightly touch the work-

piece.

– Press button 

33

 to set the zero point.

The indication “

Reset

” is shown on display
