Operation  
WARNING  
MOVING PARTS HAZARD  
To reduce the risk of serious injury, in-  
cluding cuts, amputation of fingers, and  
splashing in the eyes or on the skin:  
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), vibra-  
tion, and increased wear on parts. Always agitate the  
fluid only enough to maintain even mixing.  
D Always shut off the mixer and disconnect the air  
line before checking or repairing the mixer.  
4. Operate the agitator continuously while supplying  
paints or other fluids to the system.  
Operating the Agitator  
1. Fill the fluid supply container.  
2. Start the agitator.  
5. To stop the agitator, close the air valve in the air sup-  
ply line if you have one, or close the agitator needle  
valve.  
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: The agitator rotation may be reversed by  
switching the muffler and needle valve. Refer to Fig. 1.  
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:  
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.  
208390 1/4 npt(m) x 1/4 npt(m)

Service  
Servicing  
WARNING  
MOVING PARTS HAZARD  
To reduce the risk of serious injury, in-  
cluding cuts, amputation of fingers, and  
splashing in the eyes or on the skin:  
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 re-  
placement.  
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 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  
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.  
To prevent an explosive hazard, where  
injury and/or property damage can re-  
sult:  
NOTE: An Air Motor Repair Kit is available. Order part  
number 224954.  
D Do not operate this air motor with combustible  
Aligning the Outlet Housing after  
Repairing or Replacing the Outlet Housing  
or Air Motor  
gases.  
D Do not use kerosene or other flammable  
solvents to flush unit.  
CAUTION  
Improper installation of the outlet housing could  
cause the agitator shaft to bind against the outlet  
housing bearing and damage it.  
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 non-  
flammable solvent in a well ventilated area.  
1. Place the agitator in a vertical position and loosen the  
three outlet housing screws (17). See Parts Drawing.  
The recommended solvent for air motors and lubri-  
cated pumps is GastR Flushing Solvent (Part No.  
AH255 or AH255A) or InhibisolR Safety Solvent.  
2. Apply 25 psi (1.7 bar) minimum air pressure to the air  
motor. Adjust the needle valve so the agitator is bare-  
ly turning.  
1. Disconnect the air line and muffler.  
3. While the agitator shaft is turning, torque the three  
outlet housing screws to 80 to 100 in-lbs (9 to  
11.3 NSm).  
2. Add several teaspoons of solvent or spray the  
solvent directly into the motor.  
4. If the agitator shaft still binds, repeat steps 1 to 3  
above.  
3. Rotate the shaft by hand in both directions for a  
few minutes.  
Lubricating the Air Motor  
4. Reconnect the air line and slowly apply pressure  
until there is no trace of solvent in the exhaust air.  
CAUTION  
Not lubricating the air motor will cause air motor failure.  
5. Re-lubricate the motor with a squirt of light-weight  
oil in the chamber.  
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.
