Warning

WARNING

SKIN INJECTION HAZARD

High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

•Do not point the gun at anyone or at any part of the body.

•Do not put your hand or fingers over the gun fluid nozzle.

•Do not stop or deflect leaks with your hand, body, glove, or rag.

•Do not “blow back” fluid; this is not an air spray system.

•Follow Pressure Relief Procedure, page 32, when you stop spraying and before cleaning, checking, or servicing equipment.

•Use lowest possible pressure when flushing, priming, or troubleshooting.

•Engage spray gun piston safety lock when not spraying.

•Tighten all fluid connections before operating the equipment.

•Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. High pressure hose cannot be recoupled; replace the entire hose.

FIRE, EXPLOSION AND ELECTRIC SHOCK HAZARD

Solvent and fumes in work area can ignite or explode. High voltage components can cause electric shock. To help prevent fire, explosion, and electric shock:

•Shut off main power switch and wait 5 minutes before opening Reactor cabinet door.

•All electrical wiring must be done by trained and qualified personnel and comply with all local codes.

•Ground equipment and conductive objects. See Ground system, page 24.

•Use equipment only in well ventilated area.

•Eliminate all ignition sources, such as pilot lights, cigarettes and plastic drop cloths (potential static arc).

•Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

•Keep the work area free of debris, including solvent, rags, and gasoline.

•Hold gun firmly to side of grounded pail when triggering into pail.

•Use only grounded hoses.

•If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

•To avoid chemical reaction and explosion, do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment.

Warning

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause serious injury or death.

•For professional use only.

•Use equipment only for its intended purpose. Call your Graco distributor for information.

•Read manuals, warnings, tags, and labels before operating equipment. Follow instructions.

•Check equipment daily. Repair or replace worn or damaged parts immediately.

•Do not alter or modify equipment. Use only Graco parts and accessories.

•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 manufacturer’s warnings.

•Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

•Do not use hoses to pull equipment.

•Comply with all applicable safety regulations.

BURN HAZARD

This equipment is used with heated fluid, which can cause equipment surfaces to become very hot. To avoid severe burns:

•Do not touch hot fluid or equipment.

•Allow equipment to cool completely before touching it.

•Wear gloves if fluid temperature exceeds 110°F (43°C).

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

•Read Material Safety Data Sheet (MSDS) to know the specific hazards of the fluids you are using.

•Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

PERSONAL PROTECTIVE EQUIPMENT

You must wear proper protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury; inhalation of toxic fumes; and hearing loss. This equipment includes but is not limited to:

•Protective eyewear.

•Gloves, clothing, and respirator as recommended by the fluid and solvent manufacturer.

•Hearing protection.
