Special Warnings About Paint Sprayers Health and Safety Haz ard Nature and Cause of Haz ard Prevention of Haz ard Spraying paints, solvents and thinners mixes them with oxygen in the air. This creates a more explosive Risk of Explosion or Fire mixture than these materials in their from Flammable Materials. fluid form. Rapid fires and explosions of these mixtures can cause death or severe injury as well as significant property damage.
Spray Gun Assembly First, prepare your air supply. 1. This tool operates within a pressure range of 20 - 45 psi, and consumes 5.5 CFM of air at 45 psi. Provide yourself with a compressed air supply which will meet these requirements. Air compressors and related supplies are available from Harbor Freight Tools. 2. For best results, arrange your compressed air supply to include a filter and regulator as indicated in the schematic diagram above.
Operation 1. Prepare the work piece to be painted according to paint manufacturer’s directions. Prepare your paint mixture according to paint manufacturer’s directions. NOTE: In most cases, paint must be thinned for proper spraying. Be sure to use a thinner recommended by the paint manufacturer. 2. Fill the Paint Cup (35) no more than 2/3 full with your paint mixture. Screw the Reservoir into the Reservoir Cap (32) being sure the Reservoir Seal (33) is in place. 3.
The purpose of the solvent is to make the paint liquid so it can be applied. Once applied, the solvent evaporates, leaving the pigment and its binders in place. The solvent is also used as a clean up medium. Paint mixtures which are to be sprayed are generally less viscous (thinner) than mixtures which are to be applied with a brush. Thus you will most often have to add extra solvent to a paint which is to be sprayed.
HOW TO ADJUST PAINT FLOW AND AIR PRESSURE To adjust the spray pattern, loosen the Nozzle Lock Ring (1) by turning it counterclockwise, then rotate the Air Nozzle (2), then retighten the Nozzle Lock Ring (1). For a vertical spray pattern, the “ears” of the Air Nozzle (2) should be horizontal. For a horizontal pattern, the “ears” should be vertical. In other words, the position of the Air Nozzle and the spray pattern are opposite.
Troubleshooting Problem Possible Causes Suggested Repairs Paint breaking, spitting, fluttering or irregular spray a) Air Nozzle cracked or worn. b) Leak at attachment or seal c) Needle packing worn out d) Insufficient paint in cup e) Vent hole in paint container clogged a) Replace b) Clean threads and seal and tighten c) Clean, repair or replace packing d) Add more paint to cup e) Clean out vent hole One-sided paint pattern. a) One of the vent holes in the Air Nozzle is clogged.
