WARNING

SKIN INJECTION HAZARD

Spray from the gun/valve, hose leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury.

D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgi-

cal treatment.

D Do not point the gun/valve at anyone or at any part of the body.

D Do not put your hand or fingers over the spray tip/nozzle.

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

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

D Always have the tip guard and the trigger guard on the gun/valve when spraying.

D Be sure the gun/valve trigger safety operates before spraying.

D Lock the gun/valve trigger safety when you stop spraying.

D Follow the Pressure Relief Procedure on page 8 whenever you: are instructed to relieve pres-

sure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip/ nozzle.

D Tighten all fluid connections before operating the equipment.

D Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

D Use only Graco approved hoses. Do not remove any spring guard that is used to help protect the

hose from rupture caused by kinks or bends near the couplings.

MOVING PARTS HAZARD

Moving parts can pinch or amputate your fingers.

D Keep clear of all moving parts when starting or operating the pump.

D Before servicing the equipment, follow the Pressure Relief Procedure on page 8 to prevent the

equipment from starting unexpectedly.

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.

D Ground the equipment and the object being sprayed. Refer to Grounding on page 5.

D If there is any static sparking or you feel an electric shock while using this equipment, stop spray-

ing immediately. Do not use the equipment until you identify and correct the problem.

D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid

being sprayed.

D Keep the spray area free of debris, including solvent, rags, and gasoline.

D Electrically disconnect all equipment in the spray area.

D Extinguish all open flames or pilot lights in the spray area.

D Do not smoke in the spray area.

D Do not turn on or off any light switch in the spray area while operating or if fumes are present.

D Do not operate a gasoline engine in the spray area.

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed.

D Know the specific hazards of the fluid you are using.

D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,

state and national guidelines.

D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and

solvent manufacturer.

Installation

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the system as explained below. Also read the section FIRE AND EXPLOSION HAZARD on page 4.

Ground all of this equipment.

D Pump: Loosen the grounding lug locknut (W) and

washer (X). Insert one end of a 12 ga (1.5 mm2) minimum, ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. See Fig. 1. Order Part No. 237569 Ground Wire and Clamp. Connect the clamp end of the ground wire to a true earth ground.

D Fluid and hydraulic hoses: Use only electrically

conductive hoses.

D Hydraulic power supply: Follow manufacturer’s

recommendations.

D Spray gun or dispensing valve: Obtain grounding

through connection to a properly grounded fluid hose and pump.

D Object being sprayed: Follow the local code.

D Fluid supply container: Follow the local code.

D All solvent pails used when flushing: Follow the

local code. Use only metal pails, which are conductive. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.

To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun

firmly to the side of a grounded metal pail, then trigger the gun.
