WARNINGS INJECTION HAZARD Fluids under high pressure from spray or leaks can penetrate the skin and cause extremely serious injury, including the need for amputation. NEVER point spray gun at anyone or at any body part. NEVER put hand or fingers over the spray tip. Do not use rag or other materials over your fingers. Paint will penetrate through material and into the hand. NEVER try to stop or deflect leaks with your hand or body. NEVER wipe off build up around the spray tip.
WARNINGS CONTINUED ● High pressure spray can cause extremely serious injuries such as amputation. ● Handle the spray gun as you would a loaded firearm!! Read and understand all instruction manuals, tags, warnings, users guides & labels supplied with the spray gun, airless pump, hoses, spray tips & any other attachments before operating equipment. ● Learn & follow “Pressure Relief Procedure” of the equipment in use.

SPRAY TECHNIQUE Good Spray Gun Technique is at the core of any spray paint operation. Operator skill and efficiency is as important as good equipment and good paint. Good spray technique is a skill that can be quickly learned by following these simple instructions. If you are not familiar with spraying techniques, we recommend that you study this section of your manual and practice the proper technique on pieces of cardboard or a suitable surface.
SPRAY TECHNIQUE TOTAL GUN MOVEMENT- ARM MOVEMENT - FULL SWEEP TRIGGER POINT TRIGGER POINT THE ACTUA It is important to “trigger” the gun after gun movement (arm movement) has started and release trigger (shut gun off) before gun movement ends. Gun movement is always longer than actual paint (spray) stroke. In that manner, even blending and uniform paint coat thickness is achieved over the entire surface. When the gun is in motion as the trigger is pulled, it deposits an even amount of paint.
TIP SELECTION GUIDE Your airless spray gun can be used to spray a wide range of coatings. These coatings fall into three general catagories: architectural/industrial, line striping, and fine finishing. Each of these catagories uses a different style of tip. The line striping tips differ from standard tips as they are machined to spray heavier on the edges of the pattern to create crisper lines. The fine finish tips have double orifices to better atomize light-weight coatings, such as lacquers.
