Exhaust contains poisonous carbon monoxide, a colorless, odorless gas. Breathing exhaust can cause loss of consciousness and may lead to death. If you run the tiller in a confined or even partially enclosed area, the air you breathe could contain dangerous amounts of exhaust gas. To exhaust gas from building up, provide adequate ventilation.
Gasoline is extremely flammable, and gasoliqe vapor can explode. Allow the engine to cool if the tiller has been in operation. Refuel only outdoors in a well- ventilated area with the engine OFF. Do not overfill the fuel tank. Never smoke near gasoline, and keep other flames and sparks away.
Sturdy shoes with aggressive soles provide better traction. Turn Engine Off When Not Operating the Tiller If you need to leave the tiller for any reason, even just to inspect the area ahead, always turn the engine off.

Oxygenated Fuels Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions. If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.
Emission Control System Information Source of Emissions The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very impor- tant because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
TECHNICAL & CONSUMER INFORMATION Problems That May Affect Emissions If you are aware of any of the following symptoms, have your engine inspected and repaired by your authorized Honda servicing dealer. Hard starting or stalling after starting. Rough idle. Misfiring or backfiring under load. Afterburning (backfiring).
