5/10/15-GALLON STAINLESS STEEL TANK ASSEMBLIES – OPERATION & SERVICE CHECKS
PREPARATION
Mix and prepare material to be used
according to manufacturer’s instructions.
Strain material through a fine mesh
screen to remove lumps, skin, and
foreign matter that might enter and clog
fluid passages and/or spray equipment.
Follow pressure relief procedure above.
To add material to the tank, remove the
lid and pour directly into the tank or
container.
If desired, a U.S. or metric 1 gallon pail
of fluid can be placed directly into the
tank.
Replace the lid assembly and tighten
thumb screws (17) securely.
The air supply to the tank should include
a filter/water separator to filter dirt from
the air and remove water and oil.
Connect the material hose to the fluid
outlet ball valve (8).
OPERATION
1. Close the air inlet valve to tank. Turn
handle on regulator counterclockwise
until spring tension is relieved.
2. Turn on air supply to the tank.
3. Open the air inlet valve to the tank.
4. Open the fluid outlet valve.
5. Turn handle on tank pressure
regulator clockwise to pressurize tank.
6. Turn on atomization air to spray gun
at source of supply.
7. Test spray. For further instructions
consult literature provided with spray
gun.
8. If an air motor driven agitator is used,
start the agitator by slowly opening
up the needle valve. Air motor speed
should be regulated according to the
nature of the material being agitated.
MAINTENANCE
To clean equipment, proceed as follows:
1. Turn off the air supply.
2. Follow the pressure relief procedure.
3. Turn T-handle adjusting screw on tank
fluid pressure regulator
counterclockwise until no spring
pressure is felt.
4. Loosen thumb screws (17), tip clamps
(16) back and tip lid (11) to one side
of tank. Do not remove lid from tank.
5. Loosen spray gun air cap retaining
ring about three turns.
6. Turn on air supply.
7. Cup cloth over air cap on the gun and
pull trigger. This will force material
back through the hose into the tank.
8. Empty and clean tank and parts that
come into contact with material. Use
a solvent compatible with material
being used.
9. Pour solvent into tank.
10. Replace lid and tighten thumb
screws and clamps.
11. Spray until clean solvent appears.
12. Repeat steps 4 through 8.
LUBRICATION – Agitated Models
Refer to the service manual provided
with the air motor for lubrication
information.
The bearings in the agitator bearing
assembly are impregnated with special
non-gumming oil. Additional lubrication
is not required.
The agitator shaft seal does not require
lubrication.
WARNING
High pressure can cause serious injury.
Pressure is maintained in a pressure tank
after the system has been shut down.
Follow the pressure-relief procedure on
page 3 before opening the lid or fill port
or performing maintenance on the tank.
