• Use fresh, clean, unleaded automotive gasoline
(Leaded "regular" grade gasoline isan acceptable
substitute).

WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and forma-
tion of acids during storage. Acidic gas can damage
the fuel system of an engine while in storage. To avoid
engine problems, the fuel system should be emptied
beforestorage for30 daysor longer. Drain the gas tank,
start the engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel next season. See
Storage Instructions for additional information. Never
use engine or carburetor cleaner products in the fuel
tank or permanent damage may occur.
• TO THOROUGHLY MIX OIL AND GASOLINE, fill
an approved, clean container with recommended
gasoline to one quarter full. Add recommended oil
per 32:1 mix ratio (one gallon of gasoline requires
4 ounces of oil).
• Screw cap on container and shake vigorously. Then
remove cap and fill container with proper amount
of gasoline. Once oil and gasoline are mixed they
will not separate. DO NOT MIX OIL AND GASOLINE
DIRECTLY IN THE ENGINE FUEL TANK.
Fill fuel tank with fuel mixture using a clean funnel.
Wipe up any fuel spillage from engine and snow
thrower before starting engine.
WARNING: NEVER FILL FUEL TANK IN- J
DOORS, WHEN ENGINE IS RUNNING OR
WHILE ENGINE IS STILL HOT. DO NOT
SMOKE WHEN FILLING FUEL TANK.
