Flushing the Air Motor
WARNING
FIRE AND EXPLOSION HAZARD
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.
WARNING
HAZARDOUS VAPORS
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:
D Keep your face away from the exhaust port.
D Wear the appropriate protective clothing,
gloves, eyewear and respirator.
If the motor is sluggish or inefficient, flush it with
non-flammable solvent in a well ventilated area.
The recommended solvent for air motors and
lubricated pumps is GastR Flushing Solvent (Part No.
AH255 or AH255A) or InhibisolR Safety Solvent.
1. Disconnect the air line and muffler.
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 apply 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.

Service

Servicing
D If the unit requires more than installation of a
service kit, it is usually quickest and easiest to send
the unit to the Graco distributor for repair or
replacement.
D If the vanes need replacing or foreign material is
present in the motor chamber, an experienced
mechanic may remove the end plate opposite the
drive shaft end. Do not pry with a screwdriver. It will
dent the surface of the plate and body, causing
leaks. Use a puller tool, which will remove the end
plate while maintaining the position of the shaft.
D New vanes should have the edges with cut corners
(or the notched edges, if the vanes are reversible)
pointing toward the bottom of the vane slot.
Lubricating the Air Motor
Not lubricating the air motor will cause air motor failure.
If an air line lubricator 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. Run the agitator for
about 30 seconds.
