Fuel and OilType: The fuel is mixture of gasoline and oil. A 50 to 1 mixture is recommended (50 parts gasoline to 1 part oil). Mix it thoroughly before pouring it into the power blower fuel tank.

The octane rating of gasoline is a measure of its resistance to detonation or "knocking". Use a gasoline with an octane equal to or higher than that shown in the table below. The Antiknock Index is an average of the Research Octane No. (RON) and the Motor Octane No. (MON). The Antiknock Index is posted on service station pumps in the U.S.A. If the Antiknock Index is not posted, be sure the Research Octane No. is adequate.

Recommended engine oil: High quality 2-stroke air cooled engine oil JASO service Clasification: FC class

Pour the measured amount of 2-stroke oil into an approval gasoline container and add gasoline to the specified container amount.

NOTE○Do not use gasoline that has been stored longer than two months.○To ensure proper starting at low ambient temperatures, fresh winter grade fuel must 　be used.

Filling the Tank:●Level the engine before fueling.●Open the fuel tank cap and fill the tank with 50:1 gas/oil pre-mixed fuel.●Pour slowly to avoid "spit back" and allow air to escape from the tank.

●After allowing a few minutes warm-up period, run the engine at idling speed.

　Idling speed is about 3,000 rpm

NOTE○Turn the idle screw (C) counter-clockwise for the engine speed to decrease when idling speed is　higher than 3,000 rpm.○Turn the idle screw clockwise to increase the engine idle speed to idle specification if needed.

●Pull the recoil starter grip (A) slowly to engage the starter, then give a short, quick pull.●Press in the starter button (B) to the "Running" (Engine idle speed) position. If the engine fires,　but does not run continuously, repeat the starting procedure with the starter button to the "Running" 　position.

NOTE○Should the engine fail to start, do not try to pull the recoil starter grip too many times with the starter　button to the "Starting" position. This will cause the fuel to flood into the cylinder and make starting　even more difficult. In this case, set the starter button to the "Running" position and repeat the　starting procedure.○After starting, vary the engine speed a few times, to draw out the remaining air from the carburetor.
