Warnings

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

WARNING

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 MSDS’s 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.

• Always wear impervious gloves when spraying or cleaning equipment.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate 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

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.

• Do not plug or unplug power cords, or turn power or light s witches 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.

Warnings

WARNING

EQUIPMENT MISUSE HAZARD

Misuse 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 solv ent manuf acturer’ s warnings. For complete information about your material, request MSDS forms from distributor or retailer.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.

• Do not alter or modify equipment.

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

• Route hoses and cables awa y 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 HAZARD

Fluid from the gun/dispense valv e, 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.

MOVING PARTS HAZARD

Moving parts can pinch 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 in this manual. Disconnect power or air supply.

Isocyanate Hazard

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 e v eryone in the work area.

Isocyanate Hazard

To prevent exposing ISO to moisture:

• Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open container.

• Use moisture-proof hoses specifically designed for ISO, such as those supplied with your system.

• Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.

• Nev er use solvent on one side if it has been contaminated from the other side.

• Always lubricate threaded parts with Part 217374 ISO pump oil or grease when reassembling.

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.

Moisture Sensitivity of Isocyanates

Isocyanates (ISO) are catalysts used in two component foam and polyurea coatings. ISO will react with moisture (such as humidity) to form small, hard, abrasive crystals, which become suspended in the fluid. Eventually a film will form on the surface and the ISO will begin to gel, increasing in viscosity. If used, this partially cured ISO will reduce performance and the life of all wetted parts.

The amount of film formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the temperature.

312766P 5

Isocyanate Hazard

Foam Self-Ignition

Some materials may become self-igniting if applied too thick. Read material manufacturer’s warnings and material MSDS.

Keep Components A and B Separate

CAUTION

To prevent cross-contamination of the equipment’s wetted parts, never interchange component A and component B.

Changing Materials

• When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.

• Check with your material manufacturer for chemical compatibility.

• Some materials use catalyst on the A side, but some applications may use catalyst on the B side.

• Epoxies often have amines on the B (catalyst) side. P olyurethanes often have amines on the B (resin) side.
