Safety Guidelines
This manual contains information that is important for you to know and understand. This information relates to YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the following symbols. Please read the manual and pay attention to those sections.
IMPORTANT SAFETY INFORMATION - A HAZARD THAT MIGHT CAUSE SERIOUS INJURY OR LOSS OF LIFE.
Information for preventing damage to equipment.
Information that you should pay special attention to.
HAZARDS CAN OCCUR DURING NORMAL USE OF THIS EQUIPMENT. PLEASE READ THE FOLLOWING CHART
| WHAT TO LOOK FOR | WHAT COULD HAPPEN | HOW TO PREVENT IT |
|---|---|---|
| Flammable Spray Materials | When paints or materials are sprayed, they are broken into very small particles and mixed with air. This will cause certain paints and materials to become extremely flammable. | Never spray near open flames or pilot lights in stoves or heaters. Never smoke while spraying. Provide ample ventilation when spraying indoors. |
| Toxic Vapors | Some paints and coatings may be harmful if inhaled or allowed to come into contact with skin or eyes. | Use a mask or respirator if there is a chance of inhaling toxic sprayed materials. Masks and respirators have limits and will only provide protection against some kinds and limited amounts of toxic materials. Read mask and respirator instructions carefully. Consult with a safety expert or industrial hygienist if you are not sure about the use of a certain mask or respirator. |
| Compressed Air | Compressed air may propel dirt, metal shavings, etc. and possibly cause an injury. | Never point any nozzle or sprayer toward a person or part of the body. Always wear safety goggles or glasses when spraying. |
| Pressurized Parts | Certain parts are under pressure whenever the gun is connected to a pressurized air line. These parts may be propelled if the gun is disassembled. | Disconnect the gun from the air line, or completely depressurize the air line whenever the gun is to be disassembled. |
| Explosion Hazard - Incompatible Materials | The solvents 1,1,1-Trichloroethane and Methylene Chloride can chemically react with the aluminum used in most spray equipment, and this gun and cup, to produce an explosion hazard. | Read the label or data sheets for the material you intend to spray. 1. Do not use any type of spray coating material containing these solvents. 2. Do not use these solvents for equipment cleaning or flushing. 3. If in doubt as to whether a material is compatible - contact your material supplier. |
General Information
Spray Gun
This Craftsman Spray Gun is a bleeder type spray gun with an external mix air cap. The paint cup has a 1 quart capacity. Air flow through the spray gun is continuous, with only the flow of paint controlled by the trigger. Bleeder operation is recommended when used with continuously running portable air compressors.
Note: This gun is designed for use with most finishing materials. It is not designed for use with corrosive or highly abrasive materials. Using these materials can lead to poor performance and/or failure of this product.
Air Caps
External Mix Air Cap: The air and material are mixed outside the air cap. This type of cap is best suited for quick drying paints, such as Latex, lacquers, etc.
Fluid/Fan Adjustment
To increase volume of material, turn fluid needle adjusting screw (Ref #) counterclockwise (⚙️). To decrease, turn clockwise (⚙️). Increasing volume of material will also increase fan pattern size when using a fan pattern air cap.
Preparation for Spraying
This spray gun should be flushed with solvent prior to spraying with paint.
The fluid needle packing (11) in this gun may be loose when received. Tighten the packing retainer (12) until it binds and holds the fluid needle (8), then back off the packing retainer (approx. 1/4 turn) until the fluid needle is free to travel into the fluid tip (3).
Be sure the surface to be sprayed is dry and free of all dirt, grease, oil and loose paint. Mix and prepare the paint according to the manufacturer's instructions. The use of a Sears viscosimeter can be very helpful. Strain the material to be sprayed through a 60 to 90 mesh screen or equivalent.
Read and follow the safety precautions on page 4 before you begin.
Operation
- Shut off fluid flow through gun by turning fluid needle adjusting screw (10) clockwise as far as it will go. Do not force.
- Keep the air pressure as low as possible. Set pressure to 40 psi as a starting point.
- Hold the trigger (5) back and gradually open the fluid needle adjusting screw (10) until a desired pattern is obtained.
- Trigger the gun quickly, one second on-off. Spray a small test pattern.
- If the gun sprays too fast (runs or sags), lower the air and fluid pressure. If too slow, increase pressure. Adjust to balance pressure.
WARNING: RISK OF INJURY OR EQUIPMENT DAMAGE. DO NOT EXCEED 50 PSIG AT ANY TIME.
Maintenance
Roughly clean the spray gun after each use.
- Turn off air supply, and remove cup from lid.
- Empty the material from cup and rinse with a clean solvent (thinner).
- Fill cup with solvent and attach to the lid assembly.
- Turn on the air supply and spray solvent through the spray gun. While spraying, shake the gun up and down to remove all excess material from the lid. Repeat Steps 1-4 above with a clean solvent until all traces of material are removed.
- Turn off air supply to gun.
- To clean the vent orifice and interior of lid, the gun body assembly must be removed and wiped with solvent. This is easily accomplished by unscrewing the cup.
- Wipe the outside of the spray gun and cup with a solvent soaked cloth. DO NOT IMMERSE THE GUN IN SOLVENT - THIS WILL WASH OUT THE LUBRICANTS AND DRY OUT THE PACKINGS.
- To clean the air cap and fluid tip, remove them, soak in suitable solvent and wipe clean with a clean cloth. If the holes are plugged, use a wooden toothpick to remove any material particles. NEVER use a needle or any other metal object as this may damage the holes and result in imperfect spray patterns. When reassembling the fluid tip take care not to overtighten (5-10 in. lb. torque is recommended) or cross thread the fluid tip into the gun body.
Note: If water is used as a solvent to clean the gun, spray paint thinner or mineral spirits through the gun after cleaning to remove any excess moisture and protect parts.
After cleaning the spray gun, apply a few drops of light household oil to the fluid needle (8) next to the packing retainer (12). All springs should be given a coating of light grease periodically.
Hints for Good Spraying Results
- Hold the gun perpendicular to the surface, 6" to 8" distance.
- Follow contour.
- Overlap each stroke 50%.
- Ends are feathered by triggering. That is, begin stroke before pulling trigger and releasing just before ending the stroke.
- Spray edges and corners first. This will reduce overspray while providing good coverage on corners.
- Don't arc strokes, move the gun parallel to work.
Your pattern should normally be shaped like this: (A circular spray pattern).
If not, see Troubleshooting guide below.
Troubleshooting Guide
| PROBLEM | CAUSE | CORRECTION |
|---|---|---|
| Heavy top or bottom pattern. | Material build-up on air cap or fluid tip. Partially plugged horn holes, center holes or fluid tip hole. | Determine where material build-up is by inverting cap and test spraying. If pattern shape stays in same position, the condition is caused by material build-up on fluid tip. If pattern changes with cap movement, the condition is in the air cap. Soak cap or tip in suitable solvent and wipe clean. To clean orifices use a broom straw or toothpick. Never use a wire or hard instrument. This damages holes and distorts spray pattern. |
| Heavy right or left side pattern. | Partially plugged horn holes, center holes or fluid tip hole. | (Covered in previous row's correction) |
| Heavy center pattern. | Too much material. | Reduce fluid flow or increase air pressure. |
| Split spray pattern. | Material too thick. Not enough material. | Thin material. Reduce air pressure or increase fluid flow. |
WARNING: RISK OF INJURY OR EQUIPMENT DAMAGE. DO NOT EXCEED 50 PSIG AT ANY TIME.
