WARNING

INJECTION HAZARD

Spray from the valve, 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 medical attention.

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

D Do not put your hand or fingers over the grease fitting coupler.

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

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 Use only Graco approved hoses.

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.

D

Know the specific hazards of the fluid you are using.

D

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

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

Pressure Relief Procedure

WARNING

INJECTION HAZARD

Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

D are instructed to relieve the pressure,

D stop dispensing,

D check or service any of the system equipment,

D or install or clean the nozzle.

To reduce the risk of serious bodily injury, including fluid injection, splashing in the eyes or on the skin, or injury from moving parts, always follow this procedure whenever you shut off the pump, and before inspecting, removing, cleaning or repairing any part of the pump or system.

1.

Close the supply pump’s bleed–type master air valve (required in pneumatic systems) .

2.

Open the dispensing valve until pressure is fully relieved.

3.

Open the fluid drain valve at the pump fluid outlet.

Leave the drain valve open until you are ready to use the system again.

NOTE: If you suspect the dispensing valve, extension or grease fitting coupler is clogged, or that pressure has not been fully relieved after following all the previous steps, using a rag VERY

SLOWLY loosen the coupler or hose end coupling and allow pressure to be relieved gradually, then loosen the part completely. Now clear the clog.

309032 3

Operation

This dispense valve provides positive control of high pressure lubricants. When supplied with air, the pump will start when the valve is triggered and will stall against pressure when the trigger is released.

Adjustment

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 3.

1.
