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.

3M’sAutomaticHVLPspraygunsdeliversuperioratomizationforawiderangeofcoatings.Thestandardspraygunbody is made of light weight aluminum. The Zinc HVLP Automatic Spray Gun body is made of composite material. Manufactured for durability and dependability, both versions are easy to maintain for long-lasting performance.

3M equipment is for professional use only. Hazards can occur from equipment misuse. Any misuse of the equipment oraccessories,suchasoverpressurizing,modifyingparts,usingincompatiblechemicalsandfluids,orusingwornordamagedpartscancauseseriousbodilyinjury,fire,explosionorpropertydamage.Please read and follow all Safety Statements and Instructions.

Adjusting the Fluid FlowTheadjustablefluidcontrolislocatedattherearofthespraygun(ifequipped).Asastartingpoint,gentlyturnthe 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 thespringandwillnotaidinadjustment.Nextturntheknob counterclockwise two full turns. These adjustment procedures will serve only as a starting point. Fine tuning of these adjustments will be based on your material and technique.

Adjusting the Fan Pattern SizeThe fan adjustment screw is located at the top of the Series 52 and Series 55 models, and the fan is adjusted by remote on the Series 56 and Series 57. As a starting point, gently turn the knob clockwise until you feel no furtheradjustment.Next,turntheknobcounter-clockwiseone full rotation. The fan adjustment will allow you to spray from a small round to a full fan pattern. The pattern can also be changed from vertical to horizontal by rotating the air cap a ¼ turn.

Note: The small round pattern can be achieved by closing down the fan adjustment.

Spray Technique1. To achieve the best results when spraying material,

keep the spray gun perpendicular to the surface and maintainaconsistentdistanceofapproximately6to8inches(160-200mm)fromtheobjectbeingsprayed.

2. Apply coating with 50% overlap to achieve an even finish.

Note: Your spray gun may be made from aluminum and may contain aluminum components. Certain solvents containing Methylene Chloride and Tricloromethane are not chemically compatible with aluminum.

Read, understand and follow all safety statements as well as wear appropriate, approved personal protective equipment per the applicable MSDS and material container labels for cleaning solutions.

Lubrication:Regularlubricationisimportanttomaintainthehighperformance of your HVLP Automatic Spray Gun. Every time your spray gun is cleaned, the oil that lubricates the friction points is washed away.

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. The following illustrations identify the spray gun lubrication points.

Spray Gun Care and Cleaning cont.

ATTENTION

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.Donotexposeairregulatorsandgaugestosolvent as damage may occur.

Cleaning Process 1. Relievethepressurefromthespraygunbefore

8. Clean the front of the spray gun, using a soft-bristle brush and solvent.

9. Scrubtheretainingring,aircapandfluidnozzlewith a soft-bristle brush. To clean out air cap holes, use a small brush.

10.Cleantheaircapandfluidnozzleaftereachuse.Donotuse metal tools to clean the air cap holes as this may scratch them; scratches can distort the spray pattern. Do not soak the retaining ring in solvent for prolonged periods of time.
