Spray Gun Overview 3M spray guns were designed from the inside out for the effective, efficient, economical application of paints, adhesives, coatings and finishes. These spray guns deliver large spray patterns with very low overspray. The soft, tight, adjustable pattern with complete atomization results in a high finish quality and absolute control. Each light weight spray gun is designed for easy handling, reliability and durability and for minimum maintenance costs.

General Set Up and Spray Gun Use cont. Adjusting the Fluid Flow The adjustable fluid control is located at the rear of the spray gun (if equipped). As a starting point, gently turn the knob clockwise until you have very little needle travel. Do not over-tighten. After the needle travel has stopped, further tightening will only serve to compress the spring and will not aid in adjustment. Next turn the knob counterclockwise two full turns. These adjustment procedures will serve only as a starting point.
Spray Gun Care and Cleaning Lubrication: Regular lubrication is important to maintain the high performance of your HVLP Automatic Spray Gun. Every time your spray gun is cleaned, the oil that lubricates the friction points is washed away. 3M™ Series 56 You must lubricate all working threads after every cleaning. We recommend using a lubricant such as petroleum jelly. Using lubricants containing silicone can contaminate your entire finishing department.
Spray Gun Care and Cleaning cont. ATTENTION 8. Clean the front of the spray gun, using a soft-bristle brush and solvent. 9. Scrub the retaining ring, air cap and fluid nozzle with a soft-bristle brush. To clean out air cap holes, use a small brush. Solvent left in the spray gun air passages could result in a poor quality paint finish. Do not use any cleaning method which may allow solvent into the spray gun air passages. Do not expose air regulators and gauges to solvent as damage may occur.
