Warning

The following warnings include general safety information for this equipment. Further product specific warnings may be included in the text where applicable.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:

???Use equipment only in well ventilated area.

??? Do not fill fuel tank while engine is running or hot; shut off engine and let it cool. Fuel is flammable and can ignite or explode if spilled on hot surface.

??? When flammable liquid is sprayed or used for flushing or cleaning, keep sprayer at least 20 feet (6 m) away from explosive vapors.

???Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

???Keep work area free of debris, including solvent, rags and gasoline.

???Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are present.

???Ground equipment and conductive objects in work area. See Grounding instructions.

???Use only grounded hoses.

???Hold gun firmly to side of grounded pail when triggering into pail.

???If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

INJECTION HAZARD

High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

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

???Do not put your hand over the spray tip.

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

???Do not spray without tip guard and trigger guard installed.

???Engage trigger lock when not spraying.

???Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

???Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

???Tighten all fluid connections before operating the equipment.

???Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

ELECTRIC SHOCK HAZARD

Improper grounding, setup, or usage of the system can cause electric shock.

???Turn off and disconnect power cord before servicing equipment.

???Use only grounded electrical outlets.

???Use only 3-wire extension cords.

???Ensure ground prongs are intact on sprayer and extension cords.

MOVING PARTS HAZARD

Moving parts can pinch or amputate fingers and other body parts.

???Keep clear of moving parts.

???Do not operate equipment with protective guards or covers removed.

???Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.

Warning

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

???Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.

???Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer???s warnings.

???Check equipment daily. Repair or replace worn or damaged parts immediately.

SUCTION HAZARD

Never place hands near the pump fluid inlet when pump is operating or pressurized. Powerful suction could cause serious injury.

CARBON MONOXIDE HAZARD

Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Breathing carbon mon- oxide can cause death. Do not operate in an enclosed area.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

???Read MSDS???s to know the specific hazards of the fluids you are using.

???Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

BURN HAZARD

Equipment surfaces and fluid that???s heated can become very hot during operation. To avoid severe burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.

PERSONAL PROTECTIVE EQUIPMENT
