Impact Drilling
Set the selector switch 3 to the "Impact drill-
ing" symbol.
The selector switch 3 engages noticeably and can also
be actuated with the machine running.
Switching On and Off
To start the machine, press the On/Off switch 6 and
keep it depressed.
To lock the pressed On/Off switch 6, press the lock-
on button 5.
To switch off the machine, release the On/Off switch
6 or when it is locked with the lock-on button 5, briefly
press the On/Off switch 6 and then release it.
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 6 is pressed.
Light pressure on the On/Off switch 6 results in low
speed/impact rate. Further pressure on the switch
increases the speed/impact rate.
Preselecting the Speed/Impact Frequency
(PSB 600 RE/PSB 650 RE/PSB 650 RA)
With the thumbwheel for speed preselection 7, the
required speed/impact frequency can be preselected
even during operation.
The required speed/impact frequency depends on the
material and the working conditions, and can be deter-
mined through practical testing.
Operating Instructions
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
machine to cool down by running it for approx.
3 minutes at maximum speed with no load.

If the machine should fail despite the care taken in man-
ufacturing and testing procedures, repair should be
carried out by an after-sales service centre for Bosch
power tools.
