Symbol Definitions

Specific Safety Instructions

1. Do not direct spray at people or animals.
2. Do not exceed maximum air pressure.
3. 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.
4. Read all of the information concerning coating products and cleaning solvents. Do not use chlorinated solvents (e.g. 1‑1‑1 trichloroethylene and dichloromethane, also known as methylene chloride) to clean spray guns. Many spray guns contain aluminum, which reacts strongly to chlorinated solvents. Contact the solvent or coating manufacturer as needed regarding potential chemical reactions.
5. Industrial applications must follow OSHA requirements.
6. Spraying hazardous materials may result in serious injury or death. Do not spray pesticide, acid, corrosive material, fertilizer, or toxic chemicals.
7. Coatings 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.
8. Attach all accessories properly to the tool before connecting the air supply. A loose accessory may detach or break during operation.
9. Install an in-line shutoff valve to allow immediate control over the air supply in an emergency, even if a hose is ruptured.
10. Air hose fittings may get hot during use. Allow fittings to cool before disconnecting.

Vibration Precautions

This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury:

1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical check-ups to ensure medical problems are not being caused or worsened from use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, nervous system disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any symptoms related to vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the vibration effects on the user.
4. Use tools with the lowest vibration when there is a choice.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work.
7. To reduce vibration, maintain tool as explained in this manual. If abnormal vibration occurs, stop immediately.

Setup

Initial Setup

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.

Before Setup

1. This air tool may be shipped with a protective plug covering the air inlet. Remove this plug before set up.
2. Before first use, clean the Spray Gun using a solvent‑based thinner. If not removed, the material used for testing and corrosion p prevention will contaminate coating.

Air Supply Setup

_ Warning: _TO PREVENT SERIOUS INJURY FROM EXPLOSION:

Use only clean, dry, regulated, compressed air to power this tool. Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool.

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 and Figure B on page 8. 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.
   • Note: Do not use an automatic oiler system or add oil to airline. The oil will contaminate the coating being propelled, ruining the final result.
2. Attach an air hose to the compressor’s air outlet.
3. Connect the air hose to the air inlet of the tool. Other components, such as a coupler plug and quick coupler, will make operation more efficient, but are not required.
   • WARNING:  TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Do not install a female quick coupler on the tool. Such a coupler contains an air valve that will allow the air tool to retain pressure and operate accidentally after the air supply is disconnected.
   • Note: Air flow, and therefore tool performance, can be hindered by undersized air supply components.
4. The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.
5. Close the in-line shutoff valve between the compressor and the tool.
6. Turn on the air compressor according to the manufacturer’s directions and allow it to build up pressure until it cycles off.
7. Open the in-line shutoff valve.
8. Adjust the air compressor’s output regulator so that the air output is enough to properly power the tool, but the output will not exceed the tool’s maximum air pressure at any time. Adjust the pressure gradually, while checking the air output gauge to set the right pressure range.
9. Inspect the air connections for leaks. Repair any leaks found.
10. If the tool will not be used at this time, turn off and detach the air supply and safely discharge any residual air pressure to prevent accidental operation.

Note:  Residual air pressure should not be present after the tool is disconnected from the air supply. However, it is a good safety measure to attempt to discharge the tool in a safe fashion after disconnecting to ensure that the tool is disconnected and unpowered.

   • Note: Position the Hopper handle toward you to spray walls and ceilings; position the handle away from you to spray floors.
2. Choose the appropriate Nozzle for the job. Remove the Locking Ring to change the Nozzle, then replace and tighten the Locking Ring.
   • Note: The larger the Nozzle, the heavier the pattern.
   • Coating Preparation and Filling
   • Note: Proper coating mixture is essential. Most coatings will spray easily if they are mixed properly.
3. Mix the coating according to manufacturer’s directions.
4. You may have to adjust the mixture several times until you achieve the proper consistency. Therefore, do not fill the Hopper completely until the proper consistency is achieved.
5. Start the air compressor and set the regulator to needed pressure. Do not exceed maximum air pressure.
6. Test the consistency by spraying on a piece of scrap material.
7. Adjust the mixture, if necessary, according to the coating manufacturer’s directions.
8. If the coating is the proper consistency, but is still not spraying properly, adjustments may be made by:
   • Adjusting Air Pressure.
   • Adjusting Fluid Control Knob.
   • Changing the Nozzle.
   • Fluid Adjustment
9. Turn the Fluid Control Knob clockwise until it is fully closed.
10. After setting up a piece of scrap material, squeeze the Trigger in short bursts while turning the Fluid Control Knob counterclockwise to set the amount of fluid.
    • If spray is too fine: Reduce the air pressure or allow more coating to come out by opening the Fluid Control Knob.
    • If spray is too thick (globs of coating): Close the Fluid Control Knob slowly, checking the pattern after each adjustment.
11. When the proper consistency has been achieved, see Spraying Technique below.

Spraying Technique

_ IMPORTANT: _Proper spraying technique is ESSENTIAL to achieve good results.

1. First, prepare the Spray Gun according to the instructions under Spray Gun Setup Adjustment.
2. Fill the Hopper to no more than 3/4 full.
   • NOTICE: DO NOT STOP WHEN SPRAYING. Spraying materials will start to set and dry as soon as they come in contact with the air. They will cause a permanent clog if not cleared immediately. If discontinuing spraying for more than half an hour, turn off the air supply, disconnect Hopper from Gun Body and thoroughly rinse Hopper and Gun Body with water.
3. Experiment on scrap material to determine proper Nozzle angle, distance from the surface, and spraying pattern.
4. Use two hands, one to steady the Hopper and the other to operate the Spray Gun.
5. Squeeze the Trigger to start spraying.
   • Note: For continuous spraying, use the Trigger Lock. See Figure D.
   • CAUTION:  Air hose fittings may get hot. Allow fittings to cool before disconnecting, or wear gloves to prevent burns.
