Flush Pneumatic Air Motor
82/0216/11
If the motor is sluggish or inefficient, flush it with a
non-flammable solvent in a well ventilated area. The rec-
ommended solvent for air motors and lubricated pumps
is Gast
®
Flushing Solvent (Part No. AH255 or AH255A)
or Inhibisol
®
Safety Solvent.
1. Disconnect the air line and muffler.
2. Add several teaspoons of solvent or spray the sol-
vent directly into the motor.
3. Rotate the shaft by hand in both directions for a few
minutes.
4. Reconnect the air line, and slowly increase the air
pressure until there is no trace of solvent in the
exhaust air.
5. Re-lubricate the motor with a squirt of light-weight
oil in the chamber.
Lubricate Pneumatic Air Motor
If an air line lubricator is not installed, the air motor must
manually be lubricated every eight hours. Lubricate the
agitator air motor by placing 10-20 drops of SAE #10
light oil in the air inlet of the motor. Run the agitator for
about 30 seconds.
Lubricate Gear Box of
Pneumatic Air Motor
01/0368-1/11
NOTE: This section does not apply to pneumatic air
motors 24J182 or 24J183.
Check Oil Level
Perform the following procedure every two days.
1. Remove oil fill plug and check oil level. The proper
oil level is indicated on the outside of the gear box
housing.
2. If the oil level is low, add 140-weight SAE gear oil or
a high quality worm gear lubricant.
3. Replace fill plug and torque to 20 ft-lb (27 N•m).
NOTE: Gear box oil is easiest to drain immediately fol-
lowing motor operation while oil is still warm.
NOTE: Do not overfill. Overfilling may cause oil to leak
out of vent cap on top of gear box.
Replace Oil
Perform the following procedure after the first 250 hours
of operation. After that, perform every six months or
every 2500 operating hours.
1. Remove gear box and drain oil.
2. Refill gear box with 140-weight SAE gear oil or a
high quality worm gear lubricant.
3. Replace fill plug and torque to 20 ft-lb (27 N•m).
NOTE: Replace gear oil more often if the environment
causes oil to become contaminated during use.
Read all manufacturer’s warning and material MSDS
to know the specific hazards of the materials used.
CAUTION
Not lubricating the air motor will cause motor failure.
