! WARNING
The engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive
harm.
(California Proposition 65)
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 denes how clean an engine’s exhaust is over a period of time. A bar
graph scaled for “0” (most clean) to “10” (least clean) is used to show an engine’s Air Index
level. A 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 durabil-
ity 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 0 to 80cc)
125 hours (engine greater than 80cc)
Intermediate 125 hours (engine from 0 to 80cc)
250 hours (engine greater than 80cc)
Extended 300 hours (engine from 0 to 80cc)
500 hours (engine greater than 80cc)
1000 hours (225cc and greater)
Notice: This hangtag must remain on this engine or piece of equipment, and only be
removed by the ultimate purchaser before operation.

1. SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
Pay special attention to statement preceded by the following words.
“WARNING” indicates a strong possibility of severe personal injury or loss of life if
instructions are not followed.
“CAUTION” indicates a possibility of personal injury or equipment damage if instructions
are not followed.
EXHAUST PRECAUTIONS
• Never inhale exhaust gasses.
They contain carbon monoxide, a colorless, odorless and extremely dangerous gas which can
cause unconsciousness or death.
• Never operate the engine indoors or in a poorly ventilated area, such as a tunnel, cave, etc.
• Exercise extreme care when operating the engine near people or animals.
• Keep the exhaust pipe free of foreign objects.
REFUELING PRECAUTIONS
• Gasoline is extremely ammable and its vapors can explode if ignited.
• Do not refuel indoors or in a poorly ventilated area.
• Be sure to stop the engine prior to refueling.
• Do not remove fuel tank cap nor ll fuel tank while engine is hot or running.
Allow engine to cool at least 2 minutes before refueling.
• Do not overll the fuel tank.
• If fuel is spilled, wipe it away carefully and wait until the fuel has dried before starting the engine.
• After refueling, make sure that the fuel cap is secured to prevent spillage.
FIRE PREVENTION
• Do not operate the engine while smoking or near an open ame.
• Do not use around dry brush, twigs, cloth rags, or other ammable materials.
• Keep cooling air intake (recoil starter area) and mufer side of the engine at least 1
meter (3 feet) away from buildings, obstructions and other burnable objects.
• Keep the engine away from ammables and other hazardous material (trash, rags,
lubricants, explosives).
OTHER SAFETY PRECAUTIONS
• Place the protective covers over the rotating parts.
If rotating parts such as the drive shaft, pulley, belt, etc. are left exposed, they are potentially
hazardous. To prevent injury, equip them with protective covers or shrouds.
• Be careful of hot parts.
The mufer and other engine parts become very hot while the engine is running or just after
it has stopped. Operate the engine in a safe area and keep children away from the running
engine.

OTHER SAFETY PRECAUTIONS
• Do not touch the spark plug and ignition cable when starting and operating the engine.
• Never make adjustments on the machinery while it is connected to the engine, without rst
removing the ignition cable from the spark plug. Turning the crankshaft by hand during
adjusting or cleaning might start the engine, and cause serious injury to the operator.
• Operate the engine on a stable, level surface.
If the 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 engine with fuel in tank or with fuel strainer cock open.
• Do not move the engine while in operation when it has been removed from the equipment.
• Keep the unit dry (do not operate it in rainy conditions).
PRE-OPERATION CHECKS
• Carefully check fuel hoes and joints for looseness and fuel leakage. Leaked fuel creates a
potentially dangerous situation.
• Check bolts and nuts for looseness. A loose bolt or nut may cause serious engine trouble.
• Check the engine oil and rell if necessary.
• Keep cylinder ns and recoil starter free of dirt, grass and other debris.
• Wear sung tting working clothes when operating the engine.
Loose aprons, towel, belt, etc., may be caught in the engine or drive train, causing a
