Finding the Proper Agitator Speed

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,
always shut off the agitator and disconnect the air
line before checking or repairing the agitator.
NOTE: Attach ground wire before using agitator.
1. Fill the fluid supply container to about 3 or 4 inches
(75 to 100 mm) above the agitator blade.
2. Start the agitator, and gradually increase the speed
by turning the needle valve (1) until a vortex begins to
form in the paint.
3. Reduce the speed slightly, then fill the fluid con-
tainer.
NOTE: If an air shut-off valve is installed in the supply
line and used to stop and start the agitator, the same
agitator speed will be set each time the agitator is used
without repeating the above procedure. Order air
shut-off valves by the part numbers listed below:
208390 1/4 in. npt(m) x 1/4 in. npt(m)
208391 3/8 in. npt(m) x 3/8 in. npt(f)
208392 3/8 in. npt(f) x 1/4 in. npt(m)
208393 3/8 in. npt(m) x 3/8 in. npt(m)

Operation

Operating the Agitator

Do not operate the agitator at a high speed for a long
period of time. Excessive agitator speed can cause
the paint to foam and increase the wear on the agita-
tor parts.
Operate the agitator continuously while supplying
paints or other fluids to the system. Use the needle
valve (1) to regulate the agitator speed. Set the agita-
tor speed to thoroughly mix the paint, using the lowest
speed possible.
To stop the agitator, close the air valve in the air supply
line if you have one, or close the needle valve (1). Turn
the agitator off before removing it from the pail.
