Pressure Relief Procedure  
Material Preparation  
Follow manufacturer’s directions for mixing and  
preparing material.  
WARNING  
Strain material using a fine mesh screen to prevent  
foreign matter from entering and clogging passageways.  
Pressure tanks remain pressurized until pressure is  
manually relieved. To reduce the risk of serious injury  
from pressurized fluid or accidental spray from gun,  
always follow this procedure to relieve pressure in the  
tank:  
Tank Assembly  
1. Install tank handle and lock nut by turning handle  
clockwise 4-5 turns. Position handle so it is parallel  
to safety valve branch tee.  
• Before you check or service any part of the spray  
system.  
• Before you loosen or remove the pressure tank  
cover or fill port.  
• Whenever you stop spraying.  
2. Secure in place by tightening lock nut using a 9/16  
in. open end wrench.  
Tank handle must be attached before installing  
regulator.  
1. Shut off air supply to the tank by closing air valve.  
2. Pull ring on safety valve until pressure bleeds down.  
3. Install regulator 234393 by tightening swivel adapter  
nut 288804 onto nipple 288778. Position unit so  
gauge is facing the same direction as safety valve  
ring. Use 11/16 in. open end wrench to tighten  
swivel adapter nut.

WARNING  
3. Pour material into tank.  
Use part no. 289136 2.5 Gallon Disposable Tank  
Liners for easy clean-up. Not available for 5 Gallon  
Tank.  
• A safety valve protects tank from over pressuriza-  
tion. During each use, pull ring on safety valve to  
check if it operates freely and relieves air pressure.  
If the valve is stuck, does not operate freely, or does  
not relieve air pressure, it must be replaced.  
• Do not discard or make any alterations or substitu-  
tions to safety valve.  
• Do not make any changes to the pressure tank.  
Tampering in the form of drilling, welding, etc., will  
weaken the tank.  
4. Replace lid assembly and tighten clamps and thumb  
screws securely.  
5. Pass air supply line through Air Control Unit to filter  
dirt from air and extract water and oil. Connect air  
supply hose to air inlet fitting on tank regulator.  
6. Attach atomization air hose to the air outlet fitting  
which is directly opposite air inlet fitting on tank  
pressure regulator.  
The following information is for a typical  
installation.  
7. Connect material hose to fluid outlet fitting on top of  
tank lid.  
2. Slowly loosen thumb screws, tip lid clamps back and  
remove lid assembly.

Operation  
10. Replace lid and tighten thumb screws and clamps.  
1. Turn on air supply.  
11. Turn T-handle on tank regulator clockwise while  
pulling gun trigger fully back and spray until clean  
solvent appears.  
2. Turn T-handle adjusting screw clockwise on the tank  
pressure regulator, while pulling the gun trigger fully  
back to start material flow.  
12. Repeat steps 1-3.  
3. Continue turning T-handle clockwise until desired  
material flow is achieved. To decrease pressure turn  
T-handle counter-clockwise to a lower setting. Then  
relieve pressure in tank by pulling the ring on the  
safety valve.  
Decorative powder coating may be affected by  
solvent contact. Avoid prolonged exposure of  
solvents to powder coated areas. Tank has been  
zinc plated underneath the decorative coating for  
rust protection.  
4. Atomization air for the spray gun can be adjusted  
using the air adjusting valve on the spray gun or at  
the air regulator assembly (Model 234415 only) on  
the pressure tank.  
5. Operate spray gun according to instructions  
accompanying gun.  
Maintenance  
Cleaning the Tank  
1. Turn off main air supply to tank.  
3. Turn T-handle adjusting screw on regulator,  
counter-clockwise until no spring tension is felt.  
4. Slowly loosen thumb screws, tip clamps back and  
tip tank lid to one side.  
5. Loosen spray gun air cap ring about three turns.  
6. Turn on air supply.  
7. Hold a cloth over air cap on gun and pull trigger.  
This forces material back through the hose, into the  
tank.  
8. Empty and clean tank and parts using a suitable  
solvent.
