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.
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.
Daily Maintenance 1. Keep the displacement pump packing nut/wet cup lubricated with Airlessco TSO (Throat Seal Oil) at all times. The TSO helps protect the rod and the packings. Airlessco Throat Seal Oil 6 ounce bottle Part # 188-187 1 quart bottle Part # 188-392 2. Inspect the packing nut daily. Your pump has Airlessco’s patented Triple Life Packing System.
Pressure Relief Procedure IMPORTANT! To avoid possible serious body injury, always follow this procedure whenever the sprayer is shut off, when checking it, when installing, changing or cleaning tips, whenever you stop spraying, or when you are instructed to relieve the pressure. 1. Engage the gun safety latch. Refer to the separate instruction manual provided with your gun on its safety features and how to engage safety latch. 2. Turn the unit off. 3.
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.
Starting Up 1. Learn the Functions of the Controls. PRIME/PRESSURE (PR) RELIEF VALVE is used to prime pump and to relieve pressure from gun, hose and tip. Prime/Pressure Relief Valve (Prime/PR Valve) Used to relieve pressure from gun, hose & tip and to prime the unit when in OPEN position. (It is in open position when there is a wider gap between valve handle and cam body) When in CLOSED position, there is only a very slight gap between handle & body. When closed the system is pressurized.
Starting Up 5. When Shutting off the Sprayer a. Whenever you stop spraying, even for a short break, follow the "Pressure Relief Procedure". b. Clean the tip & gun as recommended in the seperate Gun Manual supplied with the gun/ c. Flush the sprayer at the end of each work day, if the material you are spraying is water-based, or if it could harden in the sprayer overnight. See "Flushing". Use a compatible solvent to flush, then fill the pump and hoses with an oil based solvent such as mineral spirits. d.
Striping Operation 1. Choose handle location 4. Setting the Swivel Wheel with RADIUS MEMORY™ 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 or truck. Refer to figure below a.
Spray Gun Operation SPRAY GUN Attach spray gun to airless unit and tighten fittings securely. Set the gun safety latch. (Also may be called gun safety lock, or trigger lock) * The gun safety latch should always be set when the gun is not being triggered. Read all warnings and safety precautions supplied with the spray gun and in product manual.
