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 #AH255B 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 #AH255B, 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

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 203ºF / 95ºC. 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.
