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:
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:
208390 1/4 npt(m) x 1/4 npt(m)
208391 3/8 npt(m) x 3/8 npt(f)
208392 3/8 npt(f) x 1/4 npt(m)
208393 3/8 npt(m) x 3/8 npt(m)
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.
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
switching the muffler and needle valve. Refer to Fig. 1.
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.
