STORAGE
STORAGE PREPARATION
Proper storage preparation is essential for keeping your snowthrower
trouble-free and looking good. The following steps will help to keep
rust and corrosion from impairing your snowthrower’s function and
appearance, and will make the engine easier to start when you use
the snowthrower again.
Cleaning
1. Rinse the auger housing and wheels with a garden hose. Wipe the
rest of the snowthrower with a moist rag.
2. After the snowthrower has dried, touch up any damaged paint.
Fuel
Gasoline will oxidize and deteriorate in storage. Old gasoline will
cause hard starting, and it leaves gum deposits that clog the fuel
system. If the gasoline in your engine deteriorates during storage, you
may need to have the carburetor and other fuel system components
serviced or replaced.
The length of time that gasoline can be left in your fuel tank and
carburetor without causing functional problems will vary with such
factors as gasoline blend, your storage temperatures, and whether
the fuel tank is partially or completely filled. The air in a partially filled
fuel tank promotes fuel deterioration. Very warm storage
temperatures accelerate fuel deterioration. Fuel deterioration
problems may occur within a few months, or even less if the gasoline
was not fresh when you filled the fuel tank.
The Distributor's Limited Warranty does not cover fuel system
damage or engine performance problems resulting from neglected
storage preparation.
You can extend fuel storage life by adding a fuel stabilizer that is
formulated for that purpose, or you can avoid fuel deterioration
problems by draining the fuel tank and carburetor.
Adding Fuel Stabilizer to Extend Fuel Storage Life
Fill the fuel tank with fresh gasoline. If only partially filled, air in the
tank will promote fuel deterioration during storage. If you keep a
container of gasoline for refueling, be sure that it contains only fresh
gasoline.
1. Add fuel stabilizer following the manufacturer’s instructions.
2. After adding a fuel stabilizer, run the engine outdoors for 10
minutes to be sure that treated gasoline has replaced the
untreated gasoline in the carburetor.
3. Stop the engine and turn the fuel valve to the OFF position
(page 4).
Draining the Fuel Tank and Carburetor
1. Place an approved gasoline
container below the carburetor
drain tube, and use a funnel to
avoid spilling fuel. Turn the fuel
valve to the ON position.
2. Insert a long, flat-tip
screwdriver into the access
hole on the left side. Locate the
carburetor drain screw near the
carburetor bowl. Loosen (don’t
remove) the drain screw until
the fuel starts to drain. Drain
until the fuel tank is empty, then
tighten the drain screw.
Engine Oil
1. Change the engine oil (page 10).
2. Remove the spark plug
(page 10).
3. Pour a tablespoon (5 ~ 10 cc) of
clean engine oil into the cylinder.
4. Pull the starter rope slowly
several times to distribute the oil.
5. Inspect, adjust and reinstall the
spark plug (page 10).
6. Pull the starter grip until
resistance is felt. This will close
the valves and protect the engine from internal corrosion.
Lubrication
Apply a few drops of oil or a small amount of grease to the following
parts for lubrication and rust prevention.
PLACING IN STORAGE
If your snowthrower will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
ignition. Select a well-ventilated storage area away from any
appliance that operates with a flame, such as a furnace, water heater,
or clothes dryer. Also avoid any area with a spark producing electric
motor, or where power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Unless all fuel has been drained from the fuel tank, leave the fuel
valve in the OFF position (page 4) to reduce the possibility of fuel
leakage.
DRAIN SCREW
 WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when handling
fuel.
• Stop the engine and keep heat, sparks, and flame
away.
• Handle fuel only outdoors.
• Wipe up spills immediately.
