Bosch PSB 1000 RCA Original Instructions Manual page 21

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
With the handwheel "PowerControl" 4 you can
preselect the necessary speed/impact even
when the machine is in operation.
The required speed/impact frequency depends
on the material and the working conditions, and
can be determined through practical testing.
Constant Electronic Control
Constant electronic control holds the speed con-
stant at no-load and under load, and ensures uni-
form working performance.
Working Advice
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, al-
low the machine to cool down by running it for
approx. 3 minutes at maximum speed with no
load.
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.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article number
given on the type plate of the machine.
