Reversing the Rotational Direction (see figures N – O)

The rotational direction switch 

7

 is used to reverse the rota-

tional direction of the machine. However, this is not possible 
with the On/Off switch 

8

 actuated.

Right Rotation:

 For drilling and driving in screws, push the 

rotational direction switch 

7

 left to the stop.

Left Rotation:

 For loosening and unscrewing screws and 

nuts, press the rotational direction switch 

7

 through to the 

right stop.

Setting the Operating Mode

Drilling and Screwdriving

Set the selector switch 

4

 to the “Drilling” symbol.

Impact Drilling

Set the selector switch

4

 to the “Impact drilling” 

symbol.

 engages noticeably and can also be ac-

tuated with the machine running.

start

 the machine, press the On/Off switch 

8

 and keep it 

pressed.

pressed

 On/Off switch

, press the lock-on button 

6

.

To 

switch off

 the machine, release the On/Off switch 

8

 or 

when it is locked with the lock-on button 

6

, briefly press the

Adjusting the Speed/Impact Frequency

The speed/impact rate of the switched on power tool can be 
variably adjusted, depending on how far the On/Off switch 

8

is pressed.
Light pressure on the On/Off switch 

8

 results in low speed/im-

pact rate. Further pressure on the switch increases the 
speed/impact rate.

Preselecting the Speed/Impact Frequency 
(PSB 650 RE / PSB 6500 RE / PSB 650 RA)

With the thumbwheel for speed preselection 

14

, the required 

speed/impact frequency can be preselected even during op-
eration.
The required speed/impact frequency depends on the mate-
rial and the working conditions, and can be determined 
through practical testing.

Electronic Speed Preselection (PSB 750 RCE /

PSB 750 RCA)

With the thumbwheel for electronic speed preselection 

5

, the 

required speed/impact frequency can be selected even if the 
machine is running.
The required speed/impact frequency depends on the mate-
rial and the working conditions, and can be determined 
through practical testing.

For working with low speed.

For working with maximum speed.

Working Advice

f

Apply the power tool to the screw/nut only when it is 
switched off. 

Rotating tool inserts can slip off.

After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
