Proper storage preparation is essential for keeping your snowthrower 
troublefree 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.

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.

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.
