LUBRICATION
an automatic lubricator can be installed in the air line just ahead of the motor. the lubricator should be
adjusted to feed one drop of oil per minute. lubrication is necessary for all internal moving parts and rust
prevention. excessive moisture in the air line can cause rust formation in the motor and might also cause ice
to form in the muffler due to the expansion of air through the motor. the moisture problem can be corrected
by installing a moisture separator in the line and also be installing an aftercoolor between the compressor and
air receiver.

SERVICING AIR MOTOR
if the motor is sluggish or inefficient, try flushing with recommended solvent. the recommended solvent for
air motors and lubricated pumps is Gast flushing Solvent, Part # ah255 or ah255a, Demkote 2x726 safety
solvent, inhibisol Safety Solvent or Dow chemical chlorothane.
to flush the unit, disconnect air line from the coupler plate and remove the felt inside the muffler assembly.
add several teaspoons of solvent directly into the air motor fitting. rotate the fan shaft by hand in both
directions for a few minutes. connect motor to an adjustable air supply. Slowly apply pressure until there is
no trace of solvent in exhausted air system. reinstall the felt insert and secure the muffler cap.
CAUTION:
foreign material exiting the air motor can be hazardous. Solid or liquid material exiting the
unit can cause eye or skin damage. Keep away from air stream. Keep face away from
exhaust port. eye protection is required.
CAUTION:
flush unit only in a well-ventilated area.
relubricate the motor by squirting a drop of oil in the chamber. if the vanes need replacing or foreign materials
are present in motor chamber, an experienced mechanic may remove the end plate opposite the drive shaft end.

it will dent the surface of the plate and body causing leaks. a puller tool should be used which will remove the
end plate while maintaining the position of the shaft. New vanes should have the edge with the corners cut on
angle or the notched edge towards the bottom of the vane slot.
If motor requires service, it is highly recommended that the user remove the motor from the housing as
per the instructions provided in this manual and return it to the factory for repair.
A service kit is available; however it should only be installed by a qualified mechanic. The tolerances
inside the air motor must be maintained to insure top operating performance.
SHUTDOWN AND STORAGE PROCEDURE
1) turn off air intake supply and remove plumbing.
2) remove air motor from the connecting machinery.
3) use clean, dry air at low pressure to “flush out” condensates, such as water.
4) re-lubricate the air motor with a squirt of oil in the chamber. rotate the shaft by hand several times.
5) Plug or cap each port. the unit is now ready for storage.
