WARNING

SKIN INJECTION HAZARD

Spray from the gun/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

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 tip/valve nozzle.

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

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

D Always have the tip guard and the trigger guard on the gun/valve when spraying/dispensing.

D Be sure the gun trigger safety operates before spraying.
D Lock the gun trigger safety when you stop spraying.

D Follow the Pressure Relief Procedure on page 4 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, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and re­sult in a fire or explosion and serious injury .

D If there is any static sparking or you feel an electric shock while using this equipment, stop spray-

ing/dispensing immediately. Do not use the equipment until you identify and correct the problem.

D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid

being sprayed/dispensed.

D Keep the spray/dispense area free of debris, including solvent, rags, and gasoline.

D Before operating this equipment, electrically disconnect all equipment in the spray/dispense area.

D Before operating this equipment, extinguish all open flames or pilot lights in the spray/dispense

area.

D Do not smoke in the spray/dispense area.
D Do not turn on or off any light switch in the spray/dispense area while spraying/dispensing or while

operating if fumes are present.

D Do not operate a gasoline engine in the spray/dispense area.

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.

Operation

Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

The system pressure must be manually
relieved to prevent the system from

starting or spraying accidentally. 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 areinstructedtorelievethepressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray tip.

3. On a gas engine, remove the ignition cable from
the spark plug. On electric powered equipment,
disconnect the power supply. On air powered
equipment, disconnect the air supply.

4. Shut off the water supply.

5. Disengage the gun trigger safety latch and trigger
the gun to relieve pressure. Then, engage the
safety latch again.

6. If you are not going to use a gasoline powered
