FUELING AND REFUELING THE PRUNER

FUEL MIXTURE

This product is powered by a 2-cycle engine and requires pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded gasoline and 2-cycle engine lubricant in a clean 1 gallon container approved for gasoline.

nThis engine is certified to operate on unleaded gasoline intended for automotive use.

nMix high quality 2-cycle engine lubricant at 2.6 oz. per gallon.

nDo not use automotive lubricant or 2-cycle outboard lubricant.

nDO NOT mix quantities larger than usable in a 30-day period.

PREMIUM EXACT MIX™ (50:1)

nCarefully pour fuel into the tank. Avoid spillage.

nPrior to replacing the fuel cap, clean and inspect the gasket.

nImmediately replace fuel cap and hand tighten. Wipe up any fuel spillage.

NOTE:  It is normal for smoke to be emitted from a new engine after first use.

WARNING:

Always shut off engine before fueling. Never add fuel to a machine with a running or hot engine. Move at least 30 ft. from refueling site before starting the engine. Do not smoke! Failure to heed this warning could result in serious personal injury.

OXYGENATED FUELS

Some conventional gasolines are 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 using an oxygenated fuel, make sure it is unleaded and meets the minimum octane rating requirements. Before using an oxygenated fuel, try to confirm the fuel’s contents. Some states/provinces require this information to be posted on the pump. The following are the EPA approved percentages of oxygenates:

Ethanol (ethyl or grain alcohol) 10% by volume. You may use gasoline containing up to 10% ethanol by volume. Gasoline containing ethanol may be marketed under the name “Gasohol.” Do not use E85 fuel.

MTBE (methyl tertiary butyl ether) 15% by volume. You may use gasoline containing up to 15% MTBE by volume.

Methanol (methyl or wood alcohol) 5% by volume. You may use gasoline containing up to 5% methanol by volume as long as it also contains cosolvents and corrosion inhibi- tors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of the product or your fuel system.

If you notice any undesirable operating symptoms, try anoth- er service station or switch to another brand of gasoline.

NOTE: Fuel system damage or performance problems re- sulting from the use of an oxygenated fuel containing more than the percentages of oxygenates stated previously are not covered under warranty.
