For Your Safety
Working safely with this machine is
possible only when the operating
and safety information are read
completely and the instructions
contained therein are strictly fol-
lowed.
In addition, the Section Safety In-
structions for Pneumatic Tools
must be observed.
Before using for the first time, ask
for a practical demonstration.
Dispose of the motor vanes in a
proper manner!
The motor vanes as well as the abrad-
ed material from the motor vanes that is
produced when in operation contain
Teflon. Do not heat over 400 °C since
vapours that are detrimental to health
can be produced.
Disconnect the air supply.
s
Disconnect the air supply when the machine is not
in use, before maintenance work and for the
changing of the tools.
Check the direction of rotation setting
before operating the machine!
Keep hands away from the rotating tool holder as
s
well as the tool.
Use only flawless insertion tools that are not worn.
s
Defective insertion tools can cause injuries.
Pay attention to firm seating of the insertion tools!
s
Be careful in confined working conditions.
s
As a result of the reaction torque, injuries can occur
from squeezing or pinching.
Be careful when screwing in long bolts; danger of
s
sliding off.
Place the machine on the bolt/nut only when
s
switched off.
Secure the workpiece.
s
Use clamping devices or a vice to hold the work-
piece in place. In this manner, it is held more se-
curely than with your hand and makes possible the
operation of the machine with both hands.
Be careful of torque reaction!
s
For high torque settings and reduced operating
pressure, the clutch no longer disengages.
Bosch can assure flawless functioning of the ma-
s
chine only when original accessories are used.

Air Supply
The supplied air must be free of foreign material and
humidity to protect the unit from damage, contamina-
tion and rust.
The use of a pressurised air maintenance unit is
necessary.
All fittings, connecting lines and hoses must be dimen-
sioned for the required air pressure and volume.
Avoid restrictions in the air supply resulting from, e.g.,
pinching, kinking or stretching!
In case of doubt, measure the pressure with a pres-
sure gauge at the air inlet with the unit switched on.
Maintenance Unit
The maintenance unit ensures fault-free functioning of
pneumatic tools.
It consists of two main components:
–
Filter with water separator
–
Pressure reducing valve
Observe the operating instructions of the maintenance
unit.
