Specifications Specifications This equipment is not intended for use with flammable or combustible materials used in places such as cabinet shops or other “factory”, or fixed locations. If you intend to use this equipment in this type of application, you must comply with NFPA 33 and OSHA requirements for the use of flammable and combustible materials.

Installation Installation 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. Grounding the metal pail: connect a ground wire to the pail by clamping one end to pail and other end to ground such as a water pipe.

Operation Operation 2. Lift prime/spray valve to PRIME to relieve pressure. Trigger Lock Always engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped. ti8908a ti8909a Trigger Locked Trigger Unlocked Pressure Relief Procedure ti13961a 3. Hold gun firmly to side of pail. Trigger the gun to relieve pressure. ti12936a 4. Engage trigger lock.
Setup Setup 1. Unscrew tip and guard assembly from gun. NOTE: If hose is already connected, make sure connections are tight. 4. Turn OFF power switch. ti12960a 2. Uncoil hose and connect one end to gun. Use two wrenches to tighten securely. ti2810a 5. Turn Pressure Control Knob all the way left (counter-clockwise) to minimum pressure. ti9681a 3. Connect other end of hose to sprayer.
Setup Prime and Flush Storage Fluid NOTE: These units are not intended for lacquers. 3. Place prime tube in waste pail. Before you use your sprayer for the first time or begin a new spraying project, you need to prime the sprayer and flush the storage fluid out of the sprayer. Oil- or Water-based Materials • • When spraying water-based materials, flush the system thoroughly with water.
Setup 11. Transfer suction tube to paint pail and submerge suction tube in paint. • Motor stopping indicates pump and hose are primed with paint. • If motor continues to run the sprayer is not properly primed. To reprime repeat step 8. Install Tip and Guard on Gun PAINT ti14963a 12. Turn power switch ON. 1. Engage trigger lock. ti5580a 13. When you see paint coming out of prime tube: ti8908a a. Point gun into waste pail. b. Unlock gun trigger lock. 2.
Setup Spraying Techniques Unclogging Spray Tip Preventing Excessive Tip Wear • 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. To avoid fluid splashback: • 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 19.
Setup Tip Selection Selecting Tip Hole Size Tips come in a variety of hole sizes for spraying a range of fluids. Your sprayer includes an 0.015 in (0.38 mm) tip for use in most spraying applications. Use the following table to determine the range of recommended tip hole sizes for each fluid type. If you need a tip other than the one supplied, see the Tip Selection Chart below. HINTS: • As you spray, the tip wears and enlarges.
Getting Started With Basic Techniques Getting Started With Basic Techniques Use a piece of scrap cardboard 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 Triggering Gun Pull trigger after starting stroke. Release trigger before end of stroke. Gun must be moving when trigger is pulled and released.
Shutdown and Cleaning Shutdown and Cleaning Pail Flushing 6. Place prime tube in waste pail. • For short term shutdown periods (overnight to two days) refer to Short Term Storage, page 25. • For flushing after spraying oil-based coatings, use compatible oil-based flushing fluid or mineral spirits. Read Priming and Flushing Storage Fluid, page 16. • For flushing after spraying water-based coatings, use water. Read Priming and Flushing Storage Fluid, page 16 or Power Flush, page 23.
Shutdown and Cleaning NOTE: Step 12 is for returning paint in hose back to paint pail. One 50-ft hose holds approximately 1-quart (1-liter) of paint. 13. While continuing to trigger gun, quickly move gun to redirect spray into waste pail. Continue triggering gun into waste pail until flushing fluid dispensed from gun is relatively clear. 12. To preserve paint in hose: a. Point gun into paint pail. b. Unlock gun trigger lock. ti12942a ti8909a c. 14. Stop triggering gun. Engage the trigger lock.
Shutdown and Cleaning Power Flush Power flushing is a faster method of flushing. It can only be used after spraying water-based coatings. 1. Relieve pressure, page 14. 10. Unscrew inlet screen from suction tube. Place inlet screen in waste pail. ti2040a 2. Remove tip and guard assembly from gun and place in waste pail. 3. Place empty waste and paint pails side by side. 11. Connect garden hose to suction tube with Power Flush attachment. Leave prime tube in waste pail. ti9726a 4.
Shutdown and Cleaning 19. Lift prime/spray valve to PRIME. NOTE: Step 16 is for returning paint in hose back to paint pail. One 50-ft (15-m) hose holds approximately 1-quart (1-liter) of paint. 16. To preserve paint in hose: ti13961a a. Point gun into paint pail. b. 20. Turn power switch OFF. Unlock gun trigger lock. ti2810a 21. Turn off garden hose. Close Power Flush attachment. ti8909a c. Pull and hold gun trigger. d. Lower prime/spray valve to SPRAY. ti9413a 22.
Storage Storage d. Wipe paint off outside of gun using a soft cloth moistened with water or flushing solvent. Short Term Storage (up to 2 days) Long Term Storage (more than 2 days) 1. Relieve pressure, page 14. 2. Leave suction tube and prime tube in paint pail. ti14964a • Always circulate Pump Armor storage fluid through system after cleaning. Water left in sprayer will corrode and damage pump. • Follow Shutdown and Cleaning, page 21, or Power Flush Cleaning, page 23. 1.
Storage 4. Turn pressure control knob clockwise until the pump turns on. 1. Screw inlet screen onto suction tube. ti12949a 5. When storage fluid comes out of prime tube (5-10 seconds) turn power switch OFF. ti9433a 2. Coil hose. Leave it connected to sprayer. Wrap hose around hose wrap bracket. ti2018a 6. Lower prime/spray valve to SPRAY to keep storage fluid in sprayer during storage. ti14966a ti13960a 3. Secure a plastic bag around suction tube to catch any drips. 4. Store sprayer indoors.
Maintenance and Service* Maintenance and Service* NOTICE Protect the internal drive parts of this sprayer from water. Openings in shroud allow cooling of mechanical parts and electronics inside. If water gets into these openings, the sprayer could malfunction or be permanently damaged. Paint Hoses Check hose for damage every time you spray. Do not attempt to repair hose if hose jacket or fittings are damaged. Do not use hoses shorter than 25 ft (7.6 m). Use two wrenches to tighten.
Troubleshooting Troubleshooting Check everything in this Troubleshooting Table before you bring the sprayer to an authorized service center. Problem Power switch is on and sprayer is plugged in, but motor does not run, and pump does not cycle. Cause Solution Pressure is set at zero pressure. Turn pressure control knob clockwise to increase pressure setting. Motor or control is damaged. Take sprayer to an authorized service center.* Electric outlet is not providing power.
Troubleshooting Problem Pump does not prime. Pump cycles but does not build up pressure. Cause Solution Inlet valve check ball is stuck. Remove suction tube and place a pencil into the inlet section to dislodge the ball, allowing pump to prime properly. OR Power Flush sprayer (see Operation manual). Inlet valve check ball or seat is dirty. Remove inlet housing. Clean or replace ball and seat. Outlet valve check ball is stuck. Unscrew outlet valve with a 3/4 in. socket. Remove and clean assembly.
Troubleshooting Problem Cause Pressure is set at maximum but Reversible spray tip is in UNCLOG cannot achieve a good spray pattern. position. Spray tip is too large for sprayer. Solution Rotate arrow-shaped handle on spray tip so it points forward in SPRAY position. Select smaller spray tip. Spray tip is worn beyond capability of Replace spray tip. sprayer.
