Flush the Air Motor
If the air motor is sluggish or inefficient, follow this
procedure.
The recommended solvent for air motors and lubricated
pumps is Gast
®
Flushing Solvent (Gast part number
AH255 or AH255A) or Inhibisol
®
Safety Solvent.
1.
Disconnect the air line and muffler (16a). See Parts,
page 18.
2.
Add several teaspoons of solvent, or spray the
solvent 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 not trace of solvent in the
exhaust air.
5.
Re-lubricate the motor with a squirt of lightweight oil
in the chamber.
Prolong the Life of the
Bearing Nut
•
Replace the bearing nut (8) if it is damaged or worn.
•
Do not allow fluids to dry out in the fluid section. Dry
fluid will adhere to the bearing nut (8) and could
destroy it the next time you start the agitator. Flush
the fluid section before you change colors or
coatings or store the agitator.
•
Do not operate the agitator without fluid in the drum
as this can cause excessive bearing nut (8) wear.
Do not use kerosene or other flammable solvents to
flush the air motor. Flushing with flammable solvents
could cause fire or explosion and result in serious
injury or property damage.
Hazardous fluids or toxic fumes can cause serious
injury or death if splashed in the eyes or on the skin,
swallowed, or inhaled. When flushing the air motor:
•
Perform the procedure in a well ventilated area.
•
Keep your face away from the exhaust port.
•
Wear the appropriate protective clothing, gloves,
eyewear, and respirator.
NOTICE
Use a compatible solvent to clean parts. The bearing
nut (8) is made of acetal, which is not compatible with
acidic fluids and will be damaged by them. Check your
material data sheet and/or supplier for compatibility.
Avoid getting any solvent on the air motor belt.
