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 13, when you stop spraying and before cleaning, check-
ing, or servicing equipment.
• Use lowest possible pressure when flushing, priming, or troubleshooting.
• Engage 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 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).
• 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.
• Ground equipment and conductive objects. See Grounding in Fusion Gun manual 309550 or
309856.
• Hold gun firmly to side of grounded pail when actuating 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.
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.
310649C 5
Isocyanate Hazard Keep A and B Components Separate
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe
burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.
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,
burns, and hearing loss. This equipment includes but is not limited to:
• Protective eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
• Hearing protection.
WARNING
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids
containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical
reaction and equipment rupture, and result in death, serious injury, and property damage.
Spraying materials containing isocyanates creates
potentially harmful mists, vapors, and atomized particulates.
Read material manufacturer’s warnings and material
MSDS to know specific hazards and precautions
related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient ventilation in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate personal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Isocyanate Hazard
Keep A and B
Components
Separate
CAUTION
To prevent cross-contamination of the gun’s wetted
parts, do not interchange A component (isocyanate)
and B component (resin) parts. The gun is shipped
with the A side on the left. The fluid manifold, fluid
housing, side seal cartridge, check valve cartridge,
and mix chamber are marked on the A side.
