Connecting the air supply
When the compressed air supply is connected to the inlet, the
direction of rotation will be as shown in the figure below. If
the exhaust air is to be piped away, a hose should be con-
nected to the exhaust outlet.
The compressed air supply should be connected to the corre-
sponding inlet for desired rotation direction, see figure below.
The inlet that is not in use, functions as an additional outlet
and must not be plugged.

The highest temperatures occur when the motor is running at
full pressure without load. With increasing torque, the air mo-
tor reduces the rotational speed and the temperature.
Warning

fore you use this motor.
This motor, its attachments and accessories must only be used
