Introduction INTRODUCTION The heart of the Spray & Stripe series is the time tested and contractor proven Airlessco “LP” piston paint pump. Designed for spraying 1700 gallons per year, this pump is used daily by thousands of painting professionals worldwide--with a reputation for trouble free performance that’s unmatched in the industry. They’re small, compact, easy to use, and quick to clean. Even changing colors is a breeze. Stripe with water-based paints made for traffic lines or athletic fields.
Safety Warnings TOXIC FLUID HAZARD Hazardous fluid or toxic fumes can cause serious injury or death if splashed in eyes or on skin, inhaled or swallowed. Know the hazards of the fluid you are using. Store & dispose of hazardous fluids according to manufacturer, local, state & national guidelines. ALWAYS wear protective eye wear, gloves, clothing and respirator as recommended by fluid manufacturer. ALWAYS INSPECT SPRAYING AREA • ALWAYS keep spraying area free from obstructions.
Safety Warnings HIGH PRESSURE SPRAY CAN CAUSE EXTREMELY SERIOUS INJURY. OBSERVE ALL 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 the spray gun at anyone or any part of the body. • NEVER put hands or fingers over the spray tip. Do not use a rag or any other material over your fingers. Paint will penetrate through material and into the hand.
Safety Warnings GROUNDING Ground the sprayer and other components in the system to reduce the risk of static sparking, fire or explosion which can result in serious bodily injury and property damage. Always ground all of these components: • Fluid Hose: use only grounded hoses. • Spray gun or dispensing valve: grounding is obtained through connection to a properly grounded fluid hose and pump. • Object being sprayed: according to your local code.
Safety Warnings FLUSHING Reduce risk of injection injury, static sparking or splashing by following the specific cleaning procedure on page 7. • ALWAYS follow the PRESSURE RELIEF PROCEDURE on page 10. • ALWAYS remove the spray tip before flushing. Hold a metal part of the gun firmly to the side of a metal pail and use the lowest possible fluid pressure during flushing. • NEVER use cleaning solvents with flash points below 140º F. Some of these are: acetone, benzene, ether, gasoline and naphtha.
Safety Warnings WHEN TRANSPORTING EQUIPMENT • Transport with fuel tank EMPTY or with fuel shut-off valve OFF. WHEN STORING GASOLINE OR EQUIPMENT WITH FUEL IN TANK • Store away from furnaces, stoves, water heaters and other appliances that have pilot lights or other ignition source. They can ignite gasoline vapors. Starting engine creates sparking. Sparking can ignite nearby flammable gases. Explosion and fire could result. • If there is natural or LP gas leakage in area, do not start engine.
How to Flush FIGURE 1 FIGURE 3 - Honda Engine LOCK TRIGGER TO REMOVE SPRAY TIP FIGURE 2 CONTROL VALVE FIGURE 3 - Briggs Engine FIGURE 4 Maintain firm metal to metal contact between gun and container. 1. Be sure the gun safety latch is engaged and there is no spray tip in the gun. Refer to Fig. 1. Refer to your separate instruction manual provided with your gun on its safety features and how to engage safety latch. 2.
Flushing Read prior to using your sprayer 1. New Sprayer Your Airlessco unit was factory tested in an antifreeze solution which was left in the pump. Before using oil-base paint, flush with mineral spirits only. Before using water-base paint flush with soapy water, then do a clean water flush. 2. Changing Colors Flush with a compatible solvent such as mineral spirits or water. 3. Changing from Water-Base to Oil-Base Paint Flush with soapy water, then mineral spirits. 4.
Setting Up to Stripe or Spray 1. Connect the hose and gun. a. If the hose is not already installed on the striper, remove the plastic cap plug from the outlet tee at the spray pump, and screw a conductive or grounded 3000 psi airless spray hose onto fluid outlet. b. Connect an airless spray gun to the other end of the hose. c. Do not use steel braided airless hose. Use nylon braided airless hose only. NOTE: Do not use thread sealer on swivel unions as they are made to self-seal.
Pressure Relief Procedure To avoid possible serious bodily injury, including injection, always follow this procedure whenever the sprayer is shut off, when checking or servicing it, when installing or changing the tips, whenever you stop spraying or when you are instructed to relieve the pressure. 1. Engage gun safety latch. Refer to instruction manual provided with your gun on its safety features and how to engage safety latch. 2. Turn engine off using OFF switch on the engine. 3.
Starting Up 1. Learn how to operate the control valve. The control valve sets the prime or pressure position as well as the spraying pressure. When the valve is fully counter-clockwise the unit is in the prime position. As the control valve is turned clockwise, the unit’s output pressure to the gun is gradually increased until the control valve is fully clockwise and the unit is at it’s maximum output pressure of 2500 psi. This will fully atomize any stain or paint without needing to dilute the material.
Striping Operation 1. Choose handle location The choices are, installing the handle opposite of the single wheel assembly (standard set up) or placing the handle directly over the single wheel assembly. The handle location is really a matter of personal preference, however having the handle away from the single wheel assembly allows for easier loading/unloading from a van. 2.
