Installation Installation Smaller gauge or longer extension cords may reduce sprayer performance. Grounding and Electric Requirements Fluid supply container: follow local code. Sprayer must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for electrical current due to static build up or in the event of a short circuit. • The 120 Vac sprayers require a 120 Vac, 60 Hz, 15A circuit with a grounding receptacle.

Set AllControl to PRIME/CLEAN PUMP. ti8923a ti9169a 7.
Getting Started Install Tip and Guard Spraying Techniques Preventing Excessive Tip Wear • 1. Engage trigger lock. • • Spray should be atomized (evenly distributed, no gaps at edges). Start at low pressure setting, increase pressure a little at a time until you see a good spray pattern, without tails. Spray at lowest pressure that atomizes paint. If maximum sprayer pressure is not enough for a good spray pattern, tip is too worn. See Reversible Spray Tip Selection Chart, page 12. ti8923a 2.
Getting Started Unclogging Spray Tip 3. Aim gun at piece of scrap or cardboard. To avoid fluid splashback: • Never pull gun trigger when arrow-shaped handle is between SPRAY and UNCLOG positions. 4. Unlock trigger lock. Pull trigger to clear clog. to8922a • Tip must be pushed all the way into guard. 1. To UNCLOG tip obstruction, engage trigger lock. 5. When obstruction is cleared, lock trigger lock and rotate arrow-shaped handle back to SPRAY position. ti9049a ti8923a 2.
Getting Started Choosing the Correct Tip for the Job Consider coating and surface to be sprayed. Make sure you use best tip hole size for that coating and best fan width for that surface. Tip Hole Size Tip hole size controls flow rate - the amount of paint that comes out of the gun. HINTS: • Use larger tip hole sizes with thicker coatings and smaller tip hole sizes with thinner coatings. • Maximum tip hole sizes supported by sprayer is 0.017 in. (0.43 mm).
Getting Started With Basic Techniques Getting Started With Basic Techniques Use the Practice Spray Board to practice these basic spraying techniques before you begin spraying the surface. • Hold gun 12 in. (30 cm) from surface and aim straight at surface. Tilting gun to direct spray angle causes an uneven finish. 12 in. (30 cm) even finish thick Aiming Gun Aim tip of gun at bottom edge of previous stroke, overlapping each stroke by half.
Rolling Rolling Setup • • Tighten nut with wrench while keeping gun and roller aligned. Follow Priming instructions, beginning on page 8, prior to assembling roller. After priming, only paint should come out of spray gun. Water in hose line will cause paint to run. 6. Unlock gun trigger safety. Trigger gun. Roll surface until paint is fully dispersed on roller. This may take a minute. ti8922a 1. Set AllControl to lowest ROLL setting. ti9170a • Trigger gun briefly only when you need more paint.
Rolling Rolling Techniques Ceilings, Walls and Woodwork 1. Rolling vertically, roll out the letter “M”. 1. Ceilings: Using a paint brush, apply a starting row of paint approximately the width of your paint brush where the walls and ceiling meet. tiFig5 tiFig2 2. With the roller apply paint to the ceiling, working the short way of the room and applying as wide a strip as possible. 2. Cross roll, horizontally, to spread paint. tiFig6 tiFig3 1.
Shutdown and Cleaning Shutdown and Cleaning Pail Flushing 5. Place waste and paint pail side by side. • For short term shutdown periods (overnight to two days) refer to Short Term Storage, page 21. • For flushing after spraying water-based coatings, use water. Read Priming and Flushing Storage Fluid, page 8 or Power Flush, page 19. • For flushing after spraying oil-based coatings, use compatible oil-based flushing fluid or mineral spirits.
