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.

D

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

D

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

D

Do not put your hand or fingers over the spray gun tip or extruder gun tip.

D

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

D

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

D

Check the gun diffuser operation weekly.  Refer to the gun manual.

D

Be sure the gun trigger safety operates before spraying.

D

Lock the gun trigger safety when you stop dispensing.

D

Follow the Pressure Relief Procedure on page 7 if the spray tip clogs and before cleaning,
checking, or servicing the equipment.

D

Tighten all fluid connections before operating the equipment.

D

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.

D

Fluid hoses must have spring guards on both ends to help protect them from rupture caused by
kinks or bends near the couplings.

HALOGENATED HYDROCARBON HAZARD

Never use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents, or
fluids containing such solvents in these regulators.  In the unlikely event that there is a diaphragm
failure and the vent hole in the aluminum spring cap is plugged, a serious chemical reaction could
occur, with the possibility of explosion, which could cause death, serious injury, and/or substantial
property damage.

Consult your fluid suppliers to ensure that the fluids used are compatible with aluminum parts.

TOXIC FLUID HAZARD

Graco does not manufacture or supply the reactive chemical components that may be used in this
equipment and is not responsible for injury or property loss, damage, expense or claims (direct or
consequential) that arise from the use of such chemical components.
