SAVE THESE INSTRUCTIONS.

Specific Safety Instructions

1. The warnings and precautions discussed in this manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

2. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contains chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
   • Lead from lead-based paints
   • Crystalline silica from bricks and cement or other masonry products Arsenic and chromium from
   chemically treated lumber
   Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. (California Health & Safety Code § 25249.5, et seq.)

3.   WARNING: The brass components of this product contain lead, a chemical known to the State of California to cause birth defects (or other reproductive harm). (California Health & Safety Code § 25249.5, et seq.)

4. Do not spray near open flames, pilot lights, stoves, heaters, the air compressor, or any other heat source. Most solvents and coatings are highly flammable, particularly when sprayed. Maintain a distance of at least 25 feet from the air compressor. If possible, locate the air compressor in a separate room.

5.  Paints and solvents may be harmful or fatal if swallowed or inhaled. Avoid prolonged skin contact with solvents or paints as they will irritate skin. After any contact, immediately wash off exposed area with hot, soapy water.

6. Attach all accessories properly to the tool before connecting the air supply. A loose accessory may detach or break during operation.

7.  Install an in-line shutoff valve to allow immediate control over the air supply in an emergency, even if a hose is ruptured.

8. Air hose fittings may get hot during use. Allow fittings to cool before disconnecting.

9. Coatings can produce eye irritation. When cleaning tools exercise caution when using solvents. They can be forcefully ejected from the tool’s nozzle and air passages. Wear an ANSI-approved dust mask or respirator when working around chemical mist.

10. Do not exceed the maximum pressure. Exceeding the maximum pressure will cause the safety valve to release air to prevent the tank from exceeding its maximum pressure. Exceeding the Tank’s maximum pressure can cause the pressure tank to rupture or explode.

11.  During each use, pull the ring on the safety valve to check that it operates freely and relieves air pressure. If the safety valve is stuck, does not operate freely, or does not relieve air pressure, replace the valve.

12. Do not discard or make any alterations to the safety valve. Tampering with, welding or drilling the tank can weaken it.

13. Do not use abrasive or corrosive materials or materials that can cause rust with this tank. It is not designed for those materials. To use them can damage the tank’s internal parts.

14.  Industrial applications must follow OSHA requirements.

15. Read all information concerning coating products and cleaning solvents. Chlorinated solvents, such as 1-1-1 Trichloroethane and Methylene Chloride (also known as methyl chloride) can chemically react with aluminum and explode. Many paint sprayers contain aluminum. If you are in doubt about potential chemical reactions, contact the coating or solvent manufacturer.

16. check all seals before connecting the spray tool to the air supply.

17. Make sure that the lid is fully attached to the tank before pressurizing. Do not release the lid while the tank is pressurized.

18. Do not use wrenches, pliers or other tools to tighten paint Tank clamps. Use your hands only. If gasket leaks, clean it or replace it.

Initial Tank Set Up/Assembly

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.
Note: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram near the end of this manual.

Air Supply

WARNING: TO prevents SERIOUS Injurie FROM Explosion’s:
Use only clean, dry, regulated, compressed air to power this tank. Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tank.

1. Incorporate a filter, regulator with pressure gauge,, in-line shutoff valve, and quick coupler for best service, as shown on Figure A on page 7. An in-line shutoff ball valve is an important safety device because it controls the air supply even if the air hose is ruptured. The shutoff valve should be
   a ball valve because it can be closed quickly.

2. Attach an air hose to the compressor’s air outlet. Connect the air hose to the air inlet of the tank. Other components, such as a coupler plug and quick coupler, will make operation more efficient, but are not required.
   WARNING! TO prevent SERIOUS Injurie FROM Accidental Operation: Do not install a female quick coupler on the tank. Such a coupler contains an air valve that will allow the tank to retain pressure and operate accidentally after the air supply is disconnected.
   Note: Air flow, and therefore tank performance, can be hindered by undersized air supply components. The air hose must be long enough to reach
   the work area with enough extra length to allow free movement while working.

3. Release the spray gun’s trigger.

4. Close the in-line shutoff valve between the compressor and the tank.

5. Turn on the air compressor according to the manufacturer’s directions and allow it to build up pressure until it cycles off.

6. Adjust the air compressor’s output regulator so that the air output is enough to properly power the tank, but the output will not exceed the tank’s maximum air pressure at any time. Adjust the pressure gradually, while checking the air output gauge to set the right pressure range.

7. Inspect the air connections for leaks. Repair any leaks found.

8. If the tank will not be used at this time, turn off and detach the air supply, safely discharge any residual air pressure, and release the trigger to prevent accidental operation.

Note: It is a good safety measure to attempt to discharge the tank in a safe fashion after disconnecting to ensure that the tank is disconnected and not powered.
