Warning
Warning
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-spe­cific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual 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.
SKIN INJECTION HAZARD (SPRAY GUN)
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.
SKIN INJECTION HAZARD (APPLICATOR)
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.
Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.
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
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical reaction and equipment rupture, and result in death, serious injury, and property damage.
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 mon­oxide 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
You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:
Protective eyewear
Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
Hearing protection
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
Do not operate the unit when fatigued or under the influence of drugs or alcohol.
Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
Do not leave the work area while equipment is energized or under pressure. Turn off all equipment
and follow the Pressure Relief Procedure in this manual when equipment is not in use.
Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu­facturer’s replacement parts only.
Do not alter or modify equipment.
Use equipment only for its intended purpose. Call your distributor for information.
Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
Do not kink or over bend hoses or use hoses to pull equipment.
Keep children and animals away from work area.
Comply with all applicable safety regulations.
