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.
D Ground all equipment. Refer to Grounding on page 5.
D If there is any static sparking or you feel an electric shock while using this equipment, shut off the
agitator immediately. Do not use the equipment until you identify and correct the problem.
D Do not use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents, or
fluids containing such solvents in aluminum pumps. Such use could result in a serious chemical
reaction, with the possibility of explosion.
D Do not use kerosene or other flammable solvents or combustible gases to flush the unit.
D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being dispensed.
D Keep the dispensing area free of debris, including solvent, rags, and gasoline.
D Do not smoke in the dispensing area.
D Keep a fire extinguisher in the work 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.
D Keep clear of all moving parts when starting or operating the agitator.
D Always shut off the agitator and disconnect the air line before you remove the agitator from the
drum or check or repair any part of the agitator.
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, keep your face away from the exhaust port.

Installation
WARNING
FIRE AND EXPLOSION HAZARD
Always maintain a minimum of 1 in.
clearance between rotating agitator parts
and container to prevent sparks from contact.
Installing the Agitator
1. Install the agitator on the container cover by
screwing the helix through the drum bung hole and
screwing the agitator housing into the bung hole.
Refer to the Dimension Drawing on page 11.
CAUTION
Typical Installation

(reference only)
Air Requirements
For continuous use, the 1/2 HP agitator air motor
typically requires 2 scfm (0.06 m#/min.) of air at 400
rpm and with 100 psi (7 bar) inlet pressure.
Air Line Accessories
Install an air line filter to remove harmful dirt and
moisture from the air supply. Order Part No. 106148
for 3/8 npt or 106146 for 1/2 npt.
Keep the agitator tightly mounted to the drum bung
to prevent damage to the threads from vibration.
When using a modified drum check that there is no
interference between the base of the drum and the
shaft of the agitator.
2. Position the air motor so the air line can easily be
attached to the needle valve’s 1/8 npt inlet, without
obstructing any other system components. See
Fig. 1.
3. Attach an air line quick disconnect valve or ball
valve for main air shutoff. Order Part No. 208536,
Coupler and 169969 Fitting, Quick Disconnect Air
Line Fitting.
4. Attach the air line between the needle valve’s
1/8 npt inlet and the 1/8 npt air supply manifold
outlet.

Air Inlet
CAUTION
Not lubricating the air motor will cause air motor failure.
Downstream from the filter, install an air line lubricator
for automatic air motor lubrication. 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
7. To order a 3/8” npt air line lubricator, order Part No.
214847.

Installation
Grounding
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, 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:
Remove the grounding screw (A) and lockwasher (B).
See Fig. 2. Secure the ground wire terminal (C) to the
agitator with the screw and lockwasher. Connect the
other end of the ground wire to a true earth ground.
Order Part No. 222011, Ground Wire and Clamp.

Operation
WARNING
MOVING PARTS HAZARD
To reduce the risk of serious injury, including cuts, amputation of fingers, and
splashing in the eyes or on the skin:
D Always shut off the mixer and disconnect the air
line before checking or repairing the mixer.
Operating the Agitator
1. Fill the fluid supply container.
2. Start the agitator.
3. Use the agitator needle valve to regulate the agitator
speed. The needle valve has numbered graduations
to refer to when setting the agitator speed. Set the
agitator at speeds that minimize vibration.
NOTE: If an air shut-off valve is installed in the supply
line and used to stop the agitator, the same agitator
speed will be set each time the agitator is used. Part
numbers for air shut-off valves are listed below:
CAUTION
Do not operate the agitator at a high speed for a long
period of time. Excessive agitator speed can cause
foaming of fluid (making the fluid unusable), vibration, and increased wear on parts. Always agitate the
fluid only enough to maintain even mixing.
4. Operate the agitator continuously while supplying
paints or other fluids to the system.
5. To stop the agitator, close the air valve in the air supply line if you have one, or close the agitator needle
valve.
NOTE: The agitator rotation may be reversed by
switching the muffler and needle valve. Refer to Fig. 1.

208392 3/8 npt(f) x 1/4 npt(m)
208393 3/8 npt(m) x 3/8 npt(m)
Checking Fluid Viscosity
If the agitator is in a closed drum, the agitator must be
removed to check the fluid viscosity or the fluid must be
siphoned from the 3/4 npt drum port.

Service
WARNING
MOVING PARTS HAZARD
To reduce the risk of serious injury, including cuts, amputation of fingers, and
splashing in the eyes or on the skin:
D Always shut off the mixer and disconnect the air
line before checking or repairing the mixer.
D Wear eye protection.
WARNING
FIRE AND EXPLOSION HAZARD
To prevent an explosive hazard, where
injury and/or property damage can result:
Servicing
D If the unit requires more than installation of a ser-
vice 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.
NOTE: An Air Motor Repair Kit is available. Order part
number 224954.
D Do not operate this air motor with combustible
gases.
D Do not use kerosene or other flammable
solvents to flush unit.
D Keep face away from exhaust port. Foreign
material exiting the air motor can be hazardous.
Flushing
If the motor is sluggish or inefficient, flush it with nonflammable 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.
Aligning the Outlet Housing after
Repairing or Replacing the Outlet Housing
or Air Motor
CAUTION
Improper installation of the outlet housing could
cause the agitator shaft to bind against the outlet
housing bearing and damage it.
1. Place the agitator in a vertical position and loosen the
three outlet housing screws (17). See Parts Drawing.
2. Apply 25 psi (1.7 bar) minimum air pressure to the air
motor. Adjust the needle valve so the agitator is barely turning.
3. While the agitator shaft is turning, torque the three
outlet housing screws to 80 to 100 in-lbs (9 to
11.3 NSm).
4. If the agitator shaft still binds, repeat steps 1 to 3
above.
Lubricating the Air Motor
CAUTION
5. Re-lubricate the motor with a squirt of light-weight
oil in the chamber.
GastR is a registered trademark of Gast Manufacturing.
InhibisolR is a registered trademark of Penetone Corp.
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.
