• Use equipment only in well ventilated area.

• Eliminate all ignition sources, such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

• Keep work area free of debris, including solvent, rags, and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Ground equipment and conductive objectives. See Grounding in your sprayer manual.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail.

• If there is static sparking or you feel a shock, stop operation immediately . Do not use equipment until you identify and correct the problem.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not exceed maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• Do not alter or modify equipment.

• Use equipment only for its intended purpose. Call your Graco distributor for information.

Pressure Relief Procedure

WARNING

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.

2.

Secure in place by tightening lock nut using a 9/16” open end wrench.

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:

• 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.

1.

Shut off air supply to the tank by closing air valve.

2.

Pull ring on safety valve until pressure bleeds down.

Tank handle must be attached before installing regulator.

3.

Install regulator U10004 by tightening swivel adapter nut U23040 onto nipple U09993. Position unit so gauge is facing the same direction as safety valve ring. Use 11/16” open end wrench to tighten swivel adapter nut.

Material Preparation

Follow manufacturer’s directions for mixing and preparing material.

Strain material using a fine mesh screen to prevent foreign matter from entering and clogging passageways.

Installation

Installation

WARNING

• A safety valve protects tank from over pressurization. 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 substitutions to safety valve.

• Do not make any changes to the pressure tank.

Tampering in the form of drilling, welding, etc., will weaken the tank.

1.

The following information is for a typical installation.

Follow

Pressure Relief Procedure , page 3.

2.

Slowly loosen thumb screws, tip lid clamps back and remove lid assembly.

3.

Pour material into tank. Use part no. U07050

Disposable Tank Liners for easy clean-up.

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.

7.

Connect material hose to fluid outlet fitting on top of tank lid.

Operation

Operation

1.

Turn on air supply.

2.

Turn T-handle adjusting screw clockwise on the tank pressure regulator, while pulling the gun trigger fully back to start material flow.

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.

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.

9.

Pour solvent into tank.

10. Replace lid and tighten thumb screws and clamps.

11. Turn T-handle on tank regulator clockwise while pulling gun trigger fully back and spray until clean solvent appears.

12. Repeat steps 1-3.

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.

Maintenance

Cleaning the Tank

1.

Turn off main air supply to tank.

2.

Follow Pressure Relief Procedure , page 3.

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.
