It is your responsibility to regularly inspect and make
necessary repairs to this product in order to maintain
proper operation.
Check intake and exhaust filters after first 500 hours of
operation. Clean filters and determine how frequently
filters should be checked during future operation. This
one procedure will help assure the motor’s performance
and service life.
Flushing
Flushing this product to remove excessive dirt, foreign
particles, moisture or oil that occurs in the operating
environment will help to maintain proper vane
performance. Flush the motor if it is operating slowly or
inefficiently.
Use only Gast recommended Flushing Solvent. DO
NOT use kerosene or ANY other combustible solvents
to flush this product.
1.
Disconnect air line and muffler.
2. Add flushing solvent directly into motor. If using
liquid solvent, pour several tablespoons directly
into the intake port. If using Gast recommended
spray solvent for 5-10 seconds into intake port.
3. Rotate the shaft by hand in both directions for a
few minutes.
4. You must wear eye protection for this step.
Cover exhaust with a cloth and reconnect the air
line.
5. Restart the motor at a low pressure of
approximately 10 PSI/0.7 bar until there is no
trace of solvent in the exhaust air.
6. Listen for changes in the sound of the motor. If
motor sounds smooth, you are finished. If motor
does not sound like it is running smoothly,
installing a service kit will be required
(See “Service Kit Installation”).
Check that all external accessories such as relief valves
or gauges are attached and are not damaged before
operating product.
Lubrication
Use Gast #AD220 or a detergent SAE #10 automotive
engine oil for lubricating. Lubricating is necessary to
prevent rust on all moving parts. Excessive moisture in
air line may cause rust or ice to form in the muffler
when air expands as it passes through the motor.
Install a moisture separator in the air line and an after
cooler between compressor and air receiver to help
prevent moisture problems.
Manual Lubrication
Shut the air motor down and oil after every 8 hours of
operation. Add 10-20 drops of oil to the air motor intake
port.
Automatic Lubrication
Adjust inline oiler to feed 1 drop of oil per minute for
high speed or continuous duty usage. Do Not overfeed
oil or exhaust air may become contaminated.
Cleaning sound absorber
1. Remove the sound absorber.
2. Clean the felt filter.
3. You must wear eye protection for this step.
Lubricate motor with 3-4 drops of oil.
4. Check the air compressor.
5. Listen for changes in the sound of the motor. If
motor sounds smooth, you are finished. If motor
does not sound like it running smoothly, installing
a service kit will be required (See “Service Kit
Installation”).
MAINTENANCE
WARNING
Injury Hazard
Disconnect air supply and vent all air lines.
Wear eye protection when flushing this product.
Air stream from product may contain solid or liquid
material that can result in eye or skin damage.
Flush this product in a well ventilated area.
Do Not use kerosene or other combustible solvents
to flush this product.
Failure to follow these instructions can result in eye
injury or other serious injury.
Operate the motor for approximately 2 hours at
the maximum desired load. Measure the
surface temperature of the motor on the casting
opposite the pipe ports. The maximum surface
temperature listed on the motor is for normal
environmental and installation conditions. For most air
motors, the maximum surface temperature should not
exceed 266ºF/130ºC. Do not continue to operate the
motor if the measured surface temperature exceeds
temperature listed on the motor. If your measured
temperature does exceed listed value, consult with your
Gast Distributor/Representative for a recommendation.
Shutdown
It is your responsibility to follow proper shutdown
procedures to prevent product damage.
1. Turn off air intake supply.
2. Disconnect air supply and vent all air lines.
3. Disconnect air lines.
4. Remove air motor from connecting machinery.
5. Remove the muffler.
6. Wear eye protection. Keep away
from air stream. Use clean, dry air
to remove condensation from the inlet port of the
motor.
7. Lubricate motor with a small amount of oil into the
intake port. Rotate shaft by hand several times to
distribute oil.
8. Plug or cap each port.
9. Coat output shaft with oil or grease.
10. Store motor in a dry environment.
Disposal (Please note current regulations)
Parts of the air motor or air powered gear motor,
