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 5, when you stop spraying and before cleaning, check-

ing, 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 AND EXPLOSION HAZARD

Solvent and 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 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 your Reactor manual.

• 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.

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.

Warning

WARNING

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.

Repair Kits

A repair kit is available for your pump. Kit parts are

marked with an asterisk, for example (3*). See page 23.

Kit must be purchased separately. For best results, use all parts in the kit.

Clean and Inspect

Parts

1.

Clean and inspect all parts. Intake and piston ball seats, sleeve, and displacement rod must not be worn, scratched, or damaged.

2.

Remove and clean sleeve when repacking pump.

309577G

Supply Wet-cups with Throat Seal Liquid

Supply Wet-cups with

Throat Seal Liquid

WARNING

2.

Component B (Resin) Pump: Check felt washers (21) in packing nut/wet-cup (19) daily. Keep saturated with Graco Throat Seal Liquid (TSL),

Part No. 206995, to prevent material from hardening on displacement rod. Replace felt washers when worn or contaminated with hardened material.

Pump rod and connecting rod move during operation.

Moving parts can cause serious injury such as pinching or amputation. Keep hands and fingers away from wet-cup during operation. Turn main power OFF

before filling wet cup.

1.

Component A (ISO) Pump: Keep reservoir (R)

3/4 filled with Graco Throat Seal Liquid (TSL),

Part No. 206995. Wet-cup piston (28) circulates

TSL through packing nut/wet-cup (19), to carry away isocyanate film on displacement rod.

After some time TSL will thicken and darken, and must be replaced. Thick, dirty TSL will not pump through lines and will harden in wet-cup.

Check condition of TSL every week, minimum, and change when needed.
