Warnings Warnings The following general warnings are for the setup, use, grounding, maintenance, and repair of this equipment. Additional, more specific warnings may be found throughout the body of this manual where applicable. Symbols appearing in the body of the manual refer to these general warnings. When these symbols appear throughout the manual, refer back to these pages for a description of the specific hazard.
Warnings 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: • Use equipment only in well ventilated area. • Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc). • Keep work area free of debris, including solvent, rags and gasoline.
Warnings WARNING PRESSURIZED EQUIPMENT HAZARD Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury. • Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment. • Tighten all fluid connections before operating the equipment. • Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
Grounding Grounding Ground all solvent pails used when flushing, following your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place pail on a nonconductive surface, such a paper or cardboard, which interrupts grounding continuity. 6 To maintain continuity when flushing or relieving pressure, hold a metal part of spray gun firmly to side of grounded metal pail.
Pressure Relief Procedures Pressure Relief Procedures Relieve Fluid Pressure in Gun 3. Disengage safety lock. 4. Trigger gun onto cardboard or into waste container to relieve pressure. Relieve pressure before cleaning or repairing gun. 1. Engage safety lock. 2 ! CAUTION Air supply is required for gun actuation. Do not disconnect gun air supply until fluid pressure is relieved. 2. Close manual valves. Leave air valve open. FIG. 2: Trigger Gun to Relieve Pressure 5. Engage safety lock.
Pressure Relief Procedures Relieve Air Pressure 3 Gallon Tank (Model 296981) Never transport tank while pressurized. Always relieve air pressure from tank before removing cover. CAUTION Never disconnect air hose from tank while tank is pressurized without first closing air needle valves. Failure to do so may result in contamination or air system with chemical. When depressurizing tank, always bleed off pressure slowly and avoid direct contact with fumes. 1 Quart Cup (Model 296980) 1.
Operation Operation Allow chemicals in spray gun to cool before cleaning. vent. Retighten fill cap (C) snugly. See FIG. 3. At least 1/3 of container must be empty so it can be pressurized with air. Flush Gun Do not overpressurize container. The safety valve will automatically open if pressure exceeds its factory-set level. 1. Set safety stop to CLOSED (SERVICE). 2. Close both manual valves. 3. Remove gun from coupling block. Use air to pressurize container. Do not use carbon dioxide or nitrogen.
Operation 10. Release trigger and close manual valve on service block. 13. Remove service block of gun service kit from spray gun. 11. Repeat steps 8-10 for other side of gun. 14. Set safety to CLOSED (SERVICE). 12. After initial cleaning, remove air cap, PCD retainer, and PCD. Flush a second time to ensure thorough cleaning. 15. Disconnect gun air supply.
