WARNING
GROUNDING
Improper installation or alteration of grounding plug results in risk of electric shock,
fire or explosion that could cause serious injury or death.
When repair or change the wire, do not p lug the groun d wire into a flat outlet.
Do not alter groun d prong or use adapter.
The product require a 220V, 50/60 Hz circuit with a grou nding receptacle.
You may use a 3-wire, 2.5mm2(12 AWG) (minimum).
Long lengths of cords redu ce sprayer performance.
If you are not understand the statement of groun ding, please seek help of electrician.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and p aint fumes, in work area can ignite or explode.
To help prevent fire and explo sion:
Use equipment only in well ventilated area.
Eliminate all ignition so urces; such as p ilot lights, cigarettes, portable electric lamps,
and p lastic drop cloths (potential static arc).
Sprayer generates sparks. When flammable liquid is used in or near the sprayer or for
flushing or cleaning, keep sprayer at least 20 feet (6 m) away from explosive vapors.
Keep work area free of debris, including solvent, rags, and gasoline.
Do not plug or un plug power cords or turn lights on or off when flammable fumes are
present.
Groun d equipment and conductive ob jects in work area. Read Grou nding instructions.
If there is static sparking or you feel a shock, stop operation immediately.Do not use
equipment until you identify and correct the problem.
Keep a fire extinguisher in the work area.
INJECTION HAZARD
High p ressure fluid from gun, hose leaks, or rup tured components will pierce skin. This
may look like just a cut, bu t it is a serious injury that can result in amputation. Get
immediate surgical treatment.
Do not point the gun at anyone or at any part of the body.
Do not put your hand over the spray tip.
Do not sto p or deflect leaks with your hand, bo dy, glove or rag.
Do not spray without tip gu ard and trig ger guard installed.
Engage trigg er lock when not spraying.

WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious inju ry.
Do not exceed the maximum working pressure o r temperature rating of the lowest
rated system component. Read Technical Data in all equipment manuals.
Use fluids and solvents that are compatible with equip ment wetted parts. Read
Technical Data in all equip ment manuals. Read fluid and solvent manufacturer's
warnings.For complete information about your material, request MSDS from
distributor or retailer.
Check equip ment d aily. Repair or replace worn or damaged parts immediately.
Do not alter or mod ify equipment.
Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot
surfaces.
Do not kink or overbend h oses or use hoses to pull equipment.
Comply with all applicable safety regulations.
Keep children and animals away from work area.
Do not operate the un it when fatigued or under the influence of drugs or alcohol.

Use only groun ded electrical outlets.
Use only 3-wire extension cords.
Ensure ground prongs are intact on sprayer and extension cords.
Do not expose to rain. Store indoors.
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1 -trichloroethane, methylene chloride, and/or other halog enated
hydrocarbon solvents or fluids containing such solvents in pressurized aluminum
equipment. Such use can cause serious chemcal reaction and equ ipment rupture,
and result in death, serious injury, and/or prop erty damage.
TOXIC FLUID OR FUMES HAZARD
