WARNING
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury.
DGround the equipment and the object being sprayed. Refer to Grounding on page NO TAG.
DIf there is any static sparking or you feel an electric shock while using this equipment, stop spray-
ing immediately. Do not use the equipment until you identify and correct the problem.
DProvide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being sprayed.
DKeep the spray area free of debris, including solvent, rags, and gasoline.
DElectrically disconnect all equipment in the spray area.
DExtinguish all open flames or pilot lights in the spray area.

MOVING PARTS HAZARD
Moving parts, such as the rotating blades of the agitator, can pinch or amputate your fingers or other
body parts and can cause splashing in the eyes or on the skin.
DKeep clear of all moving parts when starting or operating the agitator.
DAlways shut off the agitator and disconnect the air line before adjusting the angle of the agitator,
removing the agitator from the drum, or checking or repairing any part of the agitator.

Typical Installation
Grounding
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, the mounting
cover and all electrically conductive objects or devices
in the spray area must be properly grounded. Check
your local electrical code for detailed grounding
instructions for your area and type of equipment.
To ground the agitator, connect one end of the
ground wire (A) to the ground connector (B) on the rim
of the drum cover. See Fig. 1. Connect the other end of
the ground wire to a true earth ground.
For a ground wire and clamp, order Part No. 237569.

Installing the Agitator
This air operated agitator is for use with heavy materials,
such as mastics. It has a 2.5 HP, 1000 RPM motor, and
a shaft length of 825 mm (33.5 in.).
1. Remove the cover plate from the drum cover.
2. Loosen the nuts (206) and screws (210) and
disassemble the shaft clamp (224).
3. Loosen the setscrews (208) while holding the agitator
propellers (219) to the shaft. Use the 5/16 in. wrench
(211). Remove the propellers.
4. Guide the agitator shaft (223) through the drum cover.
The agitator will sit at an angle.
5. Fasten the agitator support (204) to the drum cover.
6. Assemble the propellers in their original positions and
torquethesetscrewsto11to15NSm (96 to 132 in-lb).
7. Be sure the agitator shaft (223) is pushed into the
agitator support (204) as far as possible, and the
setscrew (213) is tightened firmly. Use the No. 10
setscrew wrench (215).
8. Position the shaft clamp (224) around the agitator
shaft (223) and the cylinder of the displacement
pump. Fasten with the screws (210), lockwashers
(207) and nuts (206), and tighten firmly.

Operation
Provide clean, dry air to the agitator.
CAUTION
Not lubricating the air motor will cause air motor failure.
For automatic lubrication of the agitator’s air motor, install
an air line lubricator. Set the lubricator feed rate at 1 drop
of oil per minute for high speed or continuous duty usage.
Do not overfeed oil or exhaust air may become
contaminated. To manually lubricate the air motor, see
Lubricating the Air Motor on page 6. To order a 3/8”
npt air line lubricator, order Part No. 214847.
Use the needle valve (201) to control the speed of the
motor. Do not exceed 0.7 MPa (7 bar, 100 psi) air
pressure. Always use the lowest agitator speed
necessary to thoroughly mix the material. Excessive
speeds cause the fluid to aerate.
WARNING
To reduce the risk of serious, including amputation
of fingers or splashing fluid in the eyes or on the
skin, always fully close the agitator needle valve
(201) and disconnect the agitator air line before
raising the drum cover, and before checking or
repairing the agitator.

Maintenance
Lubricating the Air Motor
CAUTION
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.
If the air motor is erratic or sluggish, clean the air
motor as follows:
WARNING
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 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:
DKeep your face away from the exhaust port.
DWear 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 Gast Flushing Solvent, Gast Part No. AH255
or AH255A, Loctite Safety Solvent, or Inhibisol Safety
Solvent.
1. Disconnect the air line and muffler.
2. Add several teaspoons of solvent directly into the
motor.
3. Rotate the shaft by hand in both directions for a few
turns.
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
If the unit requires more than installation of a service
kit, it is usually quickest and easiest to send the unit to
the nearest Graco distributor for repair or replacement.
NOTE: If the vanes need replacing or foreign material
is present in the motor chamber, and 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. New vanes should
have the edge with the corners cut at an angle or the
notched edge (if reversible) toward the bottom of the
vane slot.
NOTE: If the air motor still does not operate properly,
contact a Graco distributor. Do not try to repair the air
motor yourself.
