WARNING

INJECTION HAZARD

Spray from the gun, 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.

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

Get immediate medi-

cal attention.

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 whenever you: are instructed to relieve pres-

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

Tighten all fluid connections before operating the equipment.

Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
Permanently coupled hoses cannot be repaired; replace the entire hose.

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, 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.
