Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion: • Do not spray flammable or combustible materials near an open flame or sources of ignition such as cigarettes, motors, and electrical equipment. • Paint or solvent flowing through the equipment is able to result in static electricity. Static electricity creates a risk of fire or explosion in the presence of paint or solvent fumes.
Warnings WARNING WARNING SKIN INJECTION HAZARD High-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the event that injection occurs, get immediate surgical treatment. • Do not aim the gun at, or spray any person or animal. • Keep hands and other body parts away from the discharge. For example, do not try to stop leaks with any part of the body. • Always use the nozzle tip guard. Do not spray without nozzle tip guard in place. • Use Airlessco nozzle tips.
Warnings WARNING WARNING MOVING PARTS HAZARD Moving parts can pinch, cut or amputate fingers and other body parts. • Keep clear of moving parts. • Do not operate equipment with protective guards or covers removed. • Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure and disconnect all power sources.

Operation Operation Pressure Relief Procedure 5. Re-engage gun trigger lock and close Prime/Pressure Relief Valve. To reduce risk of injury, follow this pressure relief procedure whenever you see this symbol throughout this manual, Also, perform this procedure whenever you: • Stop spraying ti14790a • Check or repair any part of this system • Install or clean spray nozzle 1. Engage the gun trigger lock.
Operation Fill the Packing Nut/Wet Cup Flushing 1. Fill the Packing Nut/Wet Cup with 5 drops of Airlessco Throat Seal Oil (TSO). • To reduce the risk of static sparking, which can cause fire or explosion, always hold a metal part of the gun firmly against the metal pail when flushing. This also reduces splashing. • Always remove the spray tip before flushing. ti15987a Flush the Sprayer 1. Flush the sprayer. See Flushing Procedure on page 8. 1.
Operation 6. Turn the engine ON/OFF switch to ON. Startup 7. Point the gun into the metal pail and hold a metal part of the gun firmly against the pail. Maintain firm metal to metal contact between gun and container. 1. Prepare the material according to the material manufacturer’s recommendations. 2. Place the suction tube into the material container. 3. Start the sprayer. ti15989a 8. Disengage the gun trigger lock and squeeze the trigger.
Operation Adjusting the Pressure Storage Short Term • To reduce the risk of injection, never hold your hand, body, fingers or hand in a rag in front of the spray tip when cleaning or checking for a cleared tip. Always point the gun toward the ground or into a waste container when checking to see if the tip is cleared or when using a self cleaning tip. • When you spray into the paint bucket, always use the lowest spray pressure and maintain firm metal to metal contact between the gun and container.
Maintenance Maintenance Electric Motor Maintenance Regular Maintenance 1. Always stop the pump at the bottom of its stroke when you take a break or at the end of the day. This helps keep material from drying on the rod, damaging the packings. 2. Keep displacement pump packing nut/wet cup 1/3 full of Airlessco Throat Seal Oil at all times. The TSO helps protect the packings and rod. 3. Lubricate Connecting Rod Pin every 3 months. Daily Maintenance Inspect the packing nut daily.
Maintenance Replacement of Belt/Belt Adjustment Servicing the Fluid Pump NOTE: The Cog Belt System does not require alignment. When upper sheave is placed on motor shaft it is pushed on until a positive stop is reached. The set screws are then loctited. The lower pulley is placed on gearbox and held in place with keyway and snap ring. The flange on upper sheave holds the belt in alignment and the belt self aligns on lower pulley eliminating having to align.
