Troubleshooting
Motor Icing
As the motor exhausts air, the compressed air rapidly
expands and lowers the temperature inside the motor
to below freezing. If there is moisture in your air sup-
ply, it can cause icing on the outside of the motor.
To help prevent icing, be sure the compressed air
supply is clean and dry. An air and water seperator
with a 20 micron filter element can remove much of the
moisture, oil and other contaminants. A dessicant air
dryer, downstream from the seperator, will dry the air
to –45
F (–42.8 C) dewpoint to provide very dry air to
the motor.
Air Leaking
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.
Relieve the pressure, then disconnect the air supply
hose from the motor.
Screw the inlet union (35) out of the air manifold.
remove the adjuster (see page 11). Remove the air
motor shield (37). Screw the union into the manifold.
Connect the air hose. Open the bleed-type master air
valve (A), and slowly open the air regulator (D). use
the Check Chart to determine the source of the leak.
WARNING
To reduce the risk of pinching or amputating your
fingers, keep them clear of all moving parts in the
motor and keep them out of the exhaust openings.
