    WarningsThe following warnings are for the setup, use, grounding, maintenance, and repair of this equip-ment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. When these symbols appear in the body of this manual, refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.

    All VA25AA, VA25CC, VA25SA, and VA25SCpumps are certified:

    WARNINGFIRE AND EXPLOSION HAZARDFlammable 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. Do not plug or unplug power cords, or turn power or light switches on or off when

    flammable fumes are present. Ground all equipment in the work area. See Grounding instructions. Use only grounded hoses. Hold gun firmly to side of grounded pail when triggering into pail. If there is static sparking or you feel a shock, stop operation immediately. Do not

    use equipment until you identify and correct the problem. Keep a working fire extinguisher in the work area.

    Static charge may build up on plastic parts during cleaning and could discharge and ignite flammable materials and gases. To help prevent fire and explosion: Clean plastic parts in a well ventilated area. Do not clean with a dry cloth. Do not operate electrostatic guns in equipment work area.

    EQUIPMENT MISUSE HAZARDMisuse can cause death or serious injury. Do not operate the unit when fatigued or under the influence of drugs or alcohol. Do not exceed the maximum working pressure or temperature rating of the lowest

    rated system component. See Technical Data in all equipment manuals. Use fluids and solvents that are compatible with equipment wetted parts. See

    Technical Data in all equipment manuals. Read fluid and solvent manufacturers warnings. For complete information about your material, request MSDS from dis-tributor or retailer.

    Do not leave the work area while equipment is energized or under pressure. Turn off all equipment and follow the Pressure Relief Procedure in this manual when equipment is not in use.

    Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturers replacement parts only.

    Do not alter or modify equipment. Use equipment only for its intended purpose. Call your distributor for information. Route hoses and cables away from traffic areas, sharp edges, moving parts, and

    hot surfaces. Do not kink or over bend hoses or use hoses to pull equipment. Keep children and animals away from work area. Comply with all applicable safety regulations.

    PRESSURIZED EQUIPMENT HAZARDFluid 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 immedi-

    ately.

    THERMAL EXPANSION HAZARDFluids subjected to heat in confined spaces, including hoses, can create a rapid rise in pressure due to the thermal expansion. Over-pressurization can result in equipment rupture and serious injury.

    Open a valve to relieve the fluid expansion during heating. Replace hoses proactively at regular intervals based on your operating conditions.

    WARNING

  • 6 859.0088

    PRESSURIZED ALUMINUM PARTS HAZARDUse of fluids that are incompatible with aluminum in pressurized equipment can cause serious chemical reaction and equipment rupture. Failure to follow this warning can result in death, serious injury, or property damage. Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated

    hydrocarbon solvents or fluids containing such solvents. Many other fluids may contain chemicals that can react with aluminum. Contact

    your material supplier for compatibility.

    PLASTIC PARTS CLEANING SOLVENT HAZARDUse only compatible water-based solvents to clean plastic structural or pressure-con-taining parts. Many solvents can degrade plastic parts and cause them to fail, which could cause serious injury or property damage. See Technical Data in this and all other equipment instruction manuals. Read fluid and solvent manufacturers warnings.

    TOXIC FLUID OR FUMES HAZARDToxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed. Read
