Important Operating Instructions GENERAL SAFETY INSTRUCTIONS • Keep the work area clean and well lit. Cluttered and dark areas increase the risk of electric shock, fire, and injury to persons. • Do not operate the tool in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. The tool is able to create sparks resulting in the ignition of the dust or fumes. • Keep bystanders, children, and visitors away while operating the tool.
Important Operating Instructions GENERAL SAFETY INSTRUCTIONS • Risk of electric shock. This tool is not provided with an insulated gripping surface. Contact with a “live” wire will also make exposed metal parts of the tool “live” and shock the operator. • Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock. • Examine the work piece to avoid contact with hidden wiring.
Important Operating Instructions GENERAL SAFETY INSTRUCTIONS • Tool service must be performed only by qualified repair personnel. • When servicing a tool, use only identical replacement parts. Use only authorized parts. • Use only the lubricants supplied with the tool or specified by the manufacturer. • Never connect to an air source that is capable of exceeding 200 PSI. Over pressurizing the tool may cause bursting, abnormal operation, breakage of the tool, or serious injury.
Important Operating Instructions PAINT PRECAUTIONS CAUTION: Paint is extremely flammable! 1. Do not operate this spray gun near open flames, pilot lights, heaters, or any other heat source. Make sure that there is adequate ventilation. Most solvents and paints are extremely flammable, especially when sprayed. Never smoke cigarettes in the same room you are working in. 2. Paints and solvents may be harmful or fatal if swallowed or inhaled. Always use a respirator when spraying.
Important Operating Instructions controls the air supply even if the air hose is ruptured. The shut-off valve should be a ball valve because it can be closed quickly. Note: if an automatic oiler system is not used, add a few drops of pneumatic tool oil to the airline connection before operation. Add a few more drops after each hour of continual use. 2. Attach an air hose to the compressor’s air outlet. Connect the air hose to the air inlet of the tool.
Important Operating Instructions WARNING: Read the ENTIRE important operating instructions before set-up or use of this product. Inspect tool before use, looking for damaged, loose, and missing parts. If any problems are found, do not use the tool until it has been repaired. WORK AREA SET-UP 1. Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to prevent distraction and injury. 2.
Important Operating Instructions 4. Start the air compressor and set the regulator to needed pressure. Do not exceed maximum air pressure. 5. Test the consistency by spraying on a piece of scrap material. If it appears too thick, add a very small amount of thinner (not included) and mix thoroughly. Use the proper thinner for the type of paint. Thin CAUTIOUSLY. Proceed slowly, adding minimal amounts at a time. Do not exceed the manufacturer’s thinning recommendations. Fan Direction 1.
Important Operating Instructions Fluid adjustment 1. Turn the fluid knob clockwise until it is fully closed. 2. After setting up a piece of scrap material, squeeze the trigger in short bursts while turning the fluid knob counterclockwise to set the amount of fluid. If spray is too fine: Reduce the air pressure or allow more paint to come out by opening the fluid knob. If spray is too thick (globs of paint): Fluid Adjustment Close the fluid knob slowly. Checking the pattern after each adjustment.
Important Operating Instructions CAUTION: 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 paint cup from gun body, and thoroughly rinse the cup and gun body following the paint manufacturer’s recommendation for cleaning, solvent type, and disposing of used solvent. 4.
