1.4 Operation
1. Turn on the air supply.
2. Turn Tee-handle adjusting screw clockwise on the tank regulator to increase material pressure; turn it counterclockwise
to decrease pressure. Maximum tank pressure is 5.5 bar (80 psi).
3. Atomization air for the spray gun can be adjusted at the gun by means of an air adjusting valve or adding an air
regulator kit to the tank.
4. Operate spray gun according to instructions accompanying gun.
• Equipped with a safety valve that continuously release excessive air when over pressurization
occurs.
• Use the air regulator valve to control and attain desired air pressure.
• To prevent continuous release of excessive air from the safety valve, use the air regulator valve
to shut off air supply when spray gun in not in use.
• To prevent accidental injury, be sure to pull the ring of the safety valve.
1.5 Maintenance : cleaning equipment
1. Turn off the main air supply to the tank.
2. Relieve all pressure from the tank by pulling the ring on safety valve until the pressure bleeds down.
3. Turn T-handle adjusting screw on tank regulator counterclockwise until no spring tension is felt.
4. Loosen thumb screws, tip clamps back and tip tank lid to one side.
5. Loosen spray gun air cap retaining ring about three turns.
