EW120R-320TR Ati PU2034 05.1.26 11:33 AM *— À WARNING: CN The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. NOTICE FEDERAL EMISSION COMPONENT DEFECT WARRANTY and CALIFORNIA EMISSION CONTROL WARRANTY are applicable to only those engines/ generators complied with EPA (Environmental Protection Agency) and CARB (California Air Resources Board) emission regulations in the U.S.A. NOTICE To the engines/generators exported to and used in the countries other than the U.S.A. warranty service shall be performed by the distributor in each country in accordance with the standard engine/generator warranty policy as applicable.

AIR INDEX To show compliance with California emission regulations, a hangtag has been provided displaying the Air Index level and durability period of this engine. The Air Index level defines how clean an engine's exhaust is over a period of time. À bar graph scaled from “0” (most clean) to “10” (least clean) is used to show an engine’s Air Index level. À lower Air Index level represents cleaner exhaust from an engine. The period of time (in hours) that the Air Index level is measured is known as the durability period. Depending on the size of the engine, a selection of time periods can be used to measure the Air Index level (see below). Descriptive Term Applicable to Emissions Durability Period Moderate - 50 hours (engine from O to 80 cc) 125 hours (engine greater than 80 cc) Intermediate - 125 hours (engine from O to 80 cc) 250 hours (engine greater than 80 cc) Extended - 300 hours (engine from O to 80 cc) 500 hours (engine greater than 80 cc) Notice : This hangtag must remain on this engine or piece of equipment, and only be removed by the ultimate purchaser before operation.

Please make sure you review each precaution carefully. Pay special attention to statement preceded by the following words. PNA “WARNING” indicates a strong possibility of severe personal injury or loss of life if instructions are not followed. ENST ‘CAUTION” indicates a possibility of personal injury or equipment damage if instructions are not followed.

PILE) : EXHAUST PRECAUTIONS

m Never inhale exhaust gasses. They contain carbon monoxide, a colorless, odorless and extremely dangerous gas which can cause unconsciousness or death. m Never operate the pump indoors or in a poorly ventilated area, such as tunnel, cave, etc. m Exercise extreme care when operating the engine near people or animals. m Keep the exhaust pipe free of foreign objects. À WARNING # Gasoline is extremely flammable and its vapors can explode if ignited. EFUELING PRECAUTIONS # Do not refuel indoors or in a poorly ventilated area. = Be sure to stop the pump prior to refueling. m Do not remove fuel tank cap nor fill fuel tank while engine is hot or running Allow engine to cool at least 2 minutes before refueling # Do not overfill the fuel tank. = lffuel is spilt, wipe it away carefully and wait until the fuel has dried before starting the engine. æ After refueling, make sure that the fuel cap is secured to prevent spillage. À WARNING # Do not operate the pump while smoking or near an open flame. IRE PREVENTION # Do not use around dry brush, twigs, cloth rags, or other flammable materials. # Keep cooling air intake (recoil starter area) and muffler side of the engine at least 1 meter (3 feet) away from buildings, obstructions and other burnable objects. m Keep the pump away from flammables and other hazardous materials (trash, rags, lubricants, explosives).

EWI120R-320TR Al PU2034 05.1.26 11:33 AM EX : orHer SAFETY PRECAUTIONS # Be careful of hot parts. The muffler and other engine parts become very hot while the pump is running or just after it has stopped. Operate the pump in a safe area and keep children away from the running pump. # Do not use diaphram pump for the mixture of water and oil # Do not touch the spark plug and ignition cable when starting and operating the engine. # Operate the pump on a stable, level surface. Ifthe engine is tilted, fuel spillage may result. NOTE Operating the engine at a steep incline may cause seizure due to improper lubrication even with a maximum oil level # Do not transport the pump with fuel in tank or with fuel strainer cock open. m Keep the unit dry (do not operate it in rainy conditions).

# Carefully check fuel hoses and joints for looseness and fuel leakage. Leaked fuel creates a potentially dangerous situation. m Check bolts and nuts for looseness. A loose bolt or nut may cause serious engine trouble. m Check the engine oil and refill if necessary. = Check the fuel level and refill if necessary. Take care not to overfill the tank. = Keep cylinder fins and recoil starter free of dirt, grass and other debris. m Wear snug fitting working clothes when operating the engine. Loose aprons, towels, belt, etc., may be caught in the engine or drive train, causing a dangerous situation
