maximum fluid outlet pressure of your pump model.
DUse fluids and solvents that are compatible with the equipment wetted parts. Refer to the
Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s
warnings.

TOXIC FLUID HAZARD
Hazardous fluids 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.
FLUID INJECTION HAZARD
Fluid from the dispensing 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.
DFluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate sur-
gical treatment.
DDo not point the dispensing valve at anyone or at any part of the body.
DDo not put your hand or fingers over the end of the dispensing valve.
DDo not stop or deflect leaks with your hand, body, glove, or rag.
DUse only extensions and couplers that are designed for use with your dispensing valve.
DDo not use a low pressure flexible nozzle with this equipment.
DFollow the Pressure Relief Procedure on page 9 if the grease fitting coupler clogs and before
cleaning, checking, or servicing the equipment.
DTighten all fluid connections before you operate 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.
