 Mount the pneumatic motor so that the axial compen-
sation touches neither the front nor the rear stop dur-
ing operation! If it strikes the rear stop, the pneumatic
motor may become damaged. If it strikes the front stop,
metal may rub against metal and cause sparks.
Mounting the Fastening Flange (see figure A)
– Unscrew the threaded ring 6 using a hook wrench 7 (left-
hand thread!) and screw in the fastening flange 8.
– Screw the pneumatic motor onto the clamping fixture on
the fastening flange 8 using two screws.
Exhaust-air Guidance
With exhaust-air guidance, the exhaust air can be diverted
through an exhaust-air hose away from your workplace, while
at the same time achieving optimal sound-proofing. Addition-
ally, your working conditions are improved, as your workplace
can no longer be contaminated though oil-containing air and
dispersed dust or chips.
– Unscrew the silencer at air outlet 5 and replace it with a
hose fitting .
– Loosen hose clamp of the exhaust-air hose , mount the ex-
haust-air hose to hose fitting and retighten the hose
clamp.
Connecting the Air Supply
 Ensure that the air pressure is not less than 6.3 bar
(91 psi) because the pneumatic motor is designed for
this operating pressure.
 Make sure that the air supply is switched off before you
connect the pneumatic motor to the air supply.
 Connect the pneumatic motor directly to the air supply
and never to the exhaust of other devices. When using
pneumatic motors with right/left rotation, ensure that
the connection is made to the correct side.
For maximum performance, the values for the inner hose di-
ameter as well as the connection threads must be adhered to
as listed in the "Technical Data" Table. To maintain the full
performance, only use hoses with a maximum length of 4 m.
The supplied compressed air must be free of foreign material
and moisture in order to protect the pneumatic motor against
damage, dirt and rust.
Note: It is necessary to use a compressed-air maintenance
unit. This ensures that the pneumatic motor functions proper-
ly.
Observe the operating instructions of the maintenance unit.
All fittings, connecting lines and hoses must be dimensioned
for the pressure and the required air volume.
Avoid restrictions in the air supply, e.g., from pinching, kink-
ing, or stretching!
If in doubt, check the pressure at the air inlet using a pressure
gauge while the pneumatic motor is switched on.

Operation
Starting Operation
The pneumatic motor works best at an operating pressure of
6.3 bar (91 psi), measured at the air inlet while the pneumat-
ic motor is switched on.
Starting and Stopping
Note: If the pneumatic motor does not start, e.g. after an ex-
tended period of rest, disconnect the air supply and turn the
motor repeatedly at the drive spindle 1. This will eliminate ad-
hesive forces.
The pneumatic motor is switched on and off by switching the
air supply on and off.
Working Advice
 Stop the pneumatic motor immediately if it does not
reach the specified no-load speed when correctly con-
nected to the air supply and running at the correct op-
erating pressure (see "Technical Data" for values)!
– Check the pneumatic motor.
– If the pneumatic motor still does not reach the specified
no-load speed after being checked, replace it.
Do not run pneumatic motors for longer than 15 minutes in
no-load.
Sudden loads cause a severe drop in speed or standstill, but
do not damage the pneumatic motor.
Reversing the rotational direction
Right rotation
– Connect the air supply hose to the hose connection 3.

0 607 957 301/... 308/... 309/... 310/... 315
– Connect the air supply hose to the hose connection 4.
Setting the Torque
The torque is controlled by means of the operating pressure.
The specified no-load speed is achieved when the silencer is
connected. If the silencer is removed, the speed must be
checked.
Excessive speed must be reduced to the rated speed using a
choke.
Excessive speeds cause unnecessary noise and reduce the
lifetime of the pneumatic motor.
Maintenance and Service
Maintenance and Cleaning
 Have maintenance and repair work performed only by
qualified specialists. This will ensure that the safety of
the pneumatic motor is maintained.
An authorized Bosch after-sales service agent will carry out
this work quickly and reliably.
