Warning
WARNING
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.
• 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
or servicing equipment.
• Use lowest possible pressure when flushing, priming, or troubleshooting.
• Never spray without tip guard and trigger guard installed.
• Engage trigger 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 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 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
• 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,
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
• Use fluids and solvents that are compatible with equipment wetted parts. See
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.

System Requirements
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
RECOIL HAZARD
The gun can recoil when triggered at very high pressure. If unprepared, this could force your hand back
or cause you to fall and injure yourself. Be sure you have firm footing and hold the gun securely.
System Requirements
•
Install a bleed-type master air valve on a pneumatic
pump air supply line to relieve air trapped between
this valve and the pump after air regulator is shut off.
Trapped air can cause the pump to cycle unexpectedly.
•
Install a fluid drain valve between the pump and gun
to relieve pressure in displacement pump, hose, and
gun. Triggering gun to relieve pressure may not be
sufficient. See
Pressure Relief Procedure
