Shindaiwa 81642 manual Mixing Fuel, Filling the Fuel Tank, Starting the Engine

Mixing Fuel

CAUTION!

Some types of gasoline contain alcohol as an oxygenate. Oxygenated gasoline may cause increased operat- ing temperatures. Under certain condi- tions, alcohol-based gasoline may also reduce the lubricating qualities of some 2-cycle mixing oils. Never use any type of gasoline containing more than 10% alcohol by volume! Generic oils and some outboard oils may not be intended for use in high-perfor- mance C4 engines, and should never be used in your Shindaiwa engine.

CAUTION!

This engine is designed to operate on a 50:1 mixture consisting of unleaded gasoline and ISO-L-EGD or JASO FC class 2-cycle mixing oil only. Use of non-approved mixing oils can lead to excessive carbon deposits.

nUse only fresh, clean unleaded gasoline with a pump octane of 87 or higher.

nMix all fuel with a 2-cycle air-cooled mixing oil that meets

or exceeds ISO-L-EGD and/or JASO FC classified oils at 50:1 gasoline/oil ratio.

Examples of 50:1 mixing quantities

n1 gallon of gasoline to 2.6 oz. mixing oil

n5 liters of gasoline to 100 ml. mixing oil

IMPORTANT!

Mix only enough fuel for your immediate needs! If fuel must be stored longer than

30 days and oil with fuel stabilizer is not used, it should first be treated with a fuel stabilizer such as StaBil™.

Oil is a registered JASO FC classified oil and also meets or exceeds ISO-L-EGD performance requirements. Shindaiwa One is recommended for use in all Shindaiwa low emissions en- gines. Shindaiwa one also includes

a fuel stabilizer.

Filling the Fuel Tank

WARNING!

Minimize the risk of fire!

n ALWAYS stop the engine and al- low to cool before refueling!

n Wipe all spilled fuel and move the engine at least 10 feet (3 meters) from the fueling point and source before starting!

n NEVER start or operate this unit if there is a fuel leak.

n NEVER start or operate this

unit if the carburetor, fuel lines, fuel tank and/or fuel tank cap are dam- aged.

n NEVER smoke or light any fires near the engine or fuel source!

n NEVER place any flammable mate- rial near the engine muffler!

nNEVER operate the engine without the muffler and spark arrester in good working condition.
