The air motor is capable of operating in a clockwise
or counterclockwise direction, depending on where
the air regulator is mounted. Clockwise direction is
preferred for this blade orientation
• When the air regulator is installed in one of the
two lower ports on the motor, a clockwise rotation
results, as viewed from the top of the motor.
• When installed on either side in one of the two
upper ports, a counterclockwise rotation results.
• The port opposite the regulator must be plugged
for the motor to operate.
The air regulator, mufflers, air gauge, nipple
connector, and swivel connector are not factory
installed on models 25C539, 25C540, and 25C541.
Follow the directions below to install these items:
1.
Screw the swivel connector (F) (see below) into
the desired port (upper or lower) in the motor (K).
2.
Screw the nipple connector (G) into the air
regulator (H) outlet. Note arrow directions on
the regulator.
3.
Attach the air regulator by screwing it into the
swivel connector.
4.
Install a plug (E) in the port opposite the regulator
(this is necessary for motor operation).
5.
Attach the air gauge (J) by screwing it into the
hole in the top of the air regulator.
6.
Install a plug (E) in the regulator in the port
opposite the air gauge.
7.
Screw one muffler (D) into the top of the motor.
8.
Screw the second muffler into the open port on
the far side of the motor from the regulator.
9.
Install the third muffler in the open port above
or below the regulator. An additional fitting may
be needed (not provided) to space the regulator
farther away from the motor.
Note
Use of the third muffler is not necessary,
but is beneficial for increased air
circulation in humid conditions. If a third
muffler is not used, the hole must be
plugged (E).
