OPERATION & MAINTENANCE
WARNING
To reduce the risk of serious bodily injury, including
cuts, amputation of fingers, and splashing in the
eyes or on the skin, always shut off the agitator and
disconnect the air line before checking or repairing
the agitator.
Operating the Agitator
NOTE: If there is a thick sediment in the bottom of the
fluid container that could clog the agitator’s fluid
tube, thoroughly mix the fluid with the plug (7) still
in place in the agitator before removing it to use
the suction feature. Refer to the PARTS DRAW-
ING.
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.
NOTE: If an air shut-off valve is installed in the supply
line and used to stop the agitator, the same agita-
tor speed will be set each time the agitator is
used without repeating the above procedure.
See ACCESSORIES.
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 ag-
itate 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 sup-
ply line if you have one, or close the agitator needle
valve.
NOTE: The agitator rotation may be reversed by switch-
ing the muffler (1a) and needle valve (11). Refer
to Fig 2.
Checking Fluid Viscosity
Install a fitting and siphon tube (not provided) into the agi-
tator’s 3/4 npt(f) fluid outlet (A). Refer to Fig 2. With the
siphon tube routed to a separate container, pump the
fluid out through the agitator outlet port to check viscosity.
Maintaining the Agitator Air Motor
If an air line lubricator is not installed, the air motor must
be manually lubricated every 8 hours. Lubricate the agi-
tator air motor by placing 2 or 3 drops of SAE No. 10 light
oil in the motor’s air inlet. Run the agitator for about 30
seconds.
The air check valve (12) allows make-up air to enter the
closed drum as fluid is drawn out through the agitator out-
let port. Refer to Fig 2. The air check valve should be in-
spected and cleaned periodically.
If the air motor operation is erratic or sluggish, flush the
motor as follows:
1.
Remove the needle valve and fill the air inlet cavity
with kerosene. Screw the needle valve back in. See
Fig 2.
2.
Soak for about 10 minutes, then run the agitator
slowly until all the kerosene is blown out. Repeat the
process if the motor still doesn’t run smoothly.
WARNING
To reduce risk of serious bodily injury, including
splashing kerosene in the eyes or on skin, keep face
and body away from exhaust while flushing.
NOTE: An Air Motor Repair Kit is available. Order part
number 224–954.
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 the PARTS
DRAWING.
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.
3.
While the agitator shaft is turning, torque the three
outlet housing screws to 80 to 100 in-lbs (9 to
11.3 N
m).
4.
If the agitator shaft still binds, repeat steps 1 to 3
above.
