WARNING

INJECTION HAZARD

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

DFluid injected into the skin is a serious injury. The injury may look like just a cut, but it is a serious injury. Get immediate medical attention.

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

DDo not put your hand or fingers over the spray tip.

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

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

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

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

DBe sure the gun trigger safety operates before spraying.

DLock the gun trigger safety when you stop spraying.

DFollow the Pressure Relief Procedure on page 9 if the spray tip clogs and before cleaning, checking or servicing the equipment.

DTighten all fluid connections before operating the equipment.

DCheck the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. Do not repair high pressure couplings; you must replace the entire hose.

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

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.

DKnow the specific hazards of the fluid you are using.

DStore hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines.

DAlways wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer.

MOVING PARTS HAZARD

Moving parts can pinch or amputate your fingers.

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

DBefore servicing the equipment, follow the Pressure Relief Procedure on page 9 to prevent the equipment from starting unexpectedly.
