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 (1a). See
on page 10.
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.
Agitator Blades
Regularly check the agitator for dried material buildup.
Clean using a rag soaked in solvent that is compatible
with the spray material and the surfaces being cleaned.
Additionally, extra precautions need to be taken if using
lower conductive materials (<1000 pS/m) such as:
•
Avoid stirring/mixing at high speeds.
•
Avoid insoluble mixtures.
•
When possible, increase the material conductivity
with additives.
•
Use liquids with a high conductivity (>1000 pS/m)
Lubricate the Air Motor
If an air line lubricator (AL) is not installed, the air motor
must be manually lubricated every 8 hours. Lubricate the
agitator air motor by placing 10–20 drops of SAE #10 light
oil in the motor’s air inlet. Oil must have an auto-ignition
rating of 365°F (185°C) or greater. Run the agitator for
about 30 seconds.
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.
Materials can become electrostatically charged when
stirred or blended. To prevent fire and explosion,
ground equipment and do not allow material to build
up on agitator. Dried material could allow static build
up and interfere with grounding.
NOTICE
Not lubricating the air motor will cause air motor
failure.
