OFF-SEASON STORAGE
PreParing engine
For engines stored over 30 days:
1. To prevent gum from forming in fuel system or on essential carbure-
tor parts:
a. If fuel tank contains oxygenated or reformulated gasoline
(gasoline blended with an alcohol or ether), run engine until it stops
from lack of fuel.
b. If fuel tank contains gasoline, either run engine until it stops from
lack of fuel or add a gasoline additive to the gas in the tank. If you
use a gas additive, run the engine for several minutes to circulate
the additive through the carburetor.
2. While the engine is still warm, change the oil.
3. Remove the spark plug and pour about 1/2 ounce of engine oil
through the spark plug hole into the cylinder. Replace spark plug
and crank the engine several times to distribute the oil.
If the snow thrower will not be used for 30 days or longer, or if it is the end of the snow season when the last possibility of snow is gone, the
equipment needs to be stored properly. Follow storage instructions below to ensure top performance from the snow thrower for many more years.
PreParing SnoW THroWer
When storing the snow thrower in an unventilated or metal stor- •
age shed, care should be taken to rustproof the equipment. Using
a light oil or silicone, coat the equipment, especially any chains,
springs, bearings and cables.
Remove all dirt from exterior of engine and equipment.
•
Follow lubrication recommendations. •
Store equipment in a clean, dry area. •
Warning
Never store snow thrower with fuel in tank indoors or in poorly venti-
lated areas, where fuel fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer or gas appliance.
CaUTion
Alcohol blended fuels (called gasohol or using ethanol or methanol)
can attract moisture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system of an engine
while in storage.
Warning
Never use engine or carburetor cleaning products in the fuel tank or
permanent damage may occur.
