Personal injury, such as splashing in the eyes,
may result from pressure in the tank. Always follow
the Pressure Relief Procedure, page 13
opening the tank cover or fill port.
Personal injury or equipment damage may result
from lifting/falling heavy equipment. To avoid
personal injury or equipment damage:
• Do not lift the drum cover and agitator without
proper assistance.
• Do not walk or stand beneath a raised elevator.
Preparing the the Fluid Fluid
Preparing Preparing the Fluid
Prepare the fluid according to manufacturer
instructions. Strain the fluid to remove large particles
that could clog the spray gun or the siphon tube.
Filling the the Tank Tank
Filling Filling the Tank
Agitators are used to keep solids in suspension,
which assists in keeping solids from clogging the
siphon tube. If solids have settled in the container,
use a shaker or some other device to thoroughly
agitate the fluid before installing and operating the
agitator.
1. Follow the Pressure Relief Procedure, page
2. Fill the fluid supply container (through the fill port
in the cover, or remove the cover and pour fluid
directly into the tank) to about 3 or 4 inches (75
to 100 mm) above the agitator blade.
If utilizing a 5-gallon tank, use one of the following
methods for paint placement:
a. Remove the cover and place a 5-gallon pail
of fluid in the 5-gallon tank.
b. Remove the cover and place a 5-gallon
antistatic polyethylene liner in the 5-gallon
tank. Pour the fluid into the antistatic
polyethylene liner.
Note
If a 5-gallon pail is used inside the
tank, an adjustment is required
to the agitator paddle position to
avoid interference. See step 12 in
Agitator, page 9

3. Be sure the ground wire is attached.
4. Replace the filler cap or cover, tighten the
c-clamp handles to 8-10 ft-lbs, approximately 1/2
to 1 turn past hand tight.

Over-pressurizing the tank or accessories could
cause a part to rupture. To reduce the risk of
serious injury, such as splashing, or property
damage, never exceed the maximum air and fluid
working pressure of the lowest rated component
in your system.
NOTICE
NOTICE NOTICE
To avoid damaging the equipment, 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. Only agitate the fluid
enough to maintain even mixing.
1. Fill the pressure tank. See
Filling the Tank, page
2. Be sure the air inlet ball valve (17) is closed.
3. Close the air regulator valves (31, 38) by turning
the knobs counterclockwise.
4. Turn on the air supply.
5. Open the air supply inlet ball valve (17).
6. To start the agitator, slowly open the agitator air
regulator valve (38). Adjust the speed of the
agitator, to about 40 to 60 rpm, if needed.
7. Open and adjust the tank air regulator (31) to the
approximate pressure desired.
8. Open the fluid outlet ball valve (18).
9. Turn on the atomizing air to the air spray gun.
Test spray a small area and adjust the pressure
as necessary. Always use the lowest possible air
pressure to obtain the desired results.
10. To stop the agitator, turn the air regulator
counterclockwise to reduce pressure to zero, or
close the air inlet ball valve (17) to the tank.
