INSTRUCTIONS
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.
This equipment is for professional use only.
Read all instruction manuals, tags, and labels before operating the equipment.
Use the equipment only for its intended purpose. If you are not sure, contact your Graco distributor.
Do not alter or modify this equipment.
Check equipment daily. Repair or replace worn or damaged parts immediately.
Do not exceed the maximum working pressure of the lowest rated system component. Refer to the
Technical Data on pages 22–23 for the maximum working pressure of this equipment.
Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the Tech-
nical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.
Do not use hoses to pull equipment.
Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose
Graco hoses to temperatures above 82C (180F) or below –40C (–40F).
Wear hearing protection when operating this equipment.
Do not lift pressurized equipment.
Comply with all applicable local, state, and national fire, electrical, and safety regulations.

WARNING
SKIN INJECTION HAZARD
Spray from the gun, 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.
Fluid injected into the skin might look like just a cut, but it is a serious injury. 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 spray tip.
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.
Always have the tip guard and the trigger guard on the gun when spraying.
Check the gun diffuser operation weekly. Refer to the gun manual.
Be sure the gun trigger safety operates before spraying.
Lock the gun trigger safety when you stop spraying.
Follow the Pressure Relief Procedure on page 8 if the spray tip clogs and before cleaning,
checking or servicing the equipment.
Tighten all fluid connections before operating the equipment.
Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
Do not repair high pressure couplings; you must replace the entire hose.
Fluid hoses must have spring guards on both ends, to help protect them from rupture caused by
kinks or bends near the couplings.
MOVING PARTS HAZARD
Moving parts, such as the air motor piston, can pinch or amputate your fingers.
Keep clear of all moving parts when starting or operating the pump.
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 re-
sult in a fire or explosion and serious injury.
Ground the equipment and the object being sprayed. Refer to Grounding on page 6.
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.
Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid be-
ing sprayed.
Keep the spray area free of debris, including solvent, rags, and gasoline.
Electrically disconnect all equipment in the spray area.
Extinguish all open flames or pilot lights in the spray area.
Do not smoke in the spray area.
Do not turn on or off any light switch in the spray area while operating or if fumes are present.
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.
Know the specific hazards of the fluid you are using.
Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.
