How To Prepare The Snow Thrower For
Storage
WARNING: Do not remove gasoline
while inside a building, near a fire,
or while you smoke. Gasoline
fumes can cause an explosion or a fire.
If the snow thrower is to be stored for an ex-
tended period, refer to the engine manufactur-
er's operating manual (included with some
models) for important maintenance or storage
details.
1. Drain the fuel tank.
2. Let the engine run until it is out of gasoline.
3. Never store the snow thrower with fuel in the
tank inside a building where ignition sources
are present such as hot water and space
heaters, clothes dryers, and the like. Allow
the engine (motor) to cool before storing in
any enclosure.
4. Remove the spark plug from the cylinder.
Pour one ounce of oil into the cylinder. Slow-
ly pull the recoil−start grip so that the oil will
protect the cylinder. Install a new spark plug
in the cylinder.
5. Thoroughly clean the snow thrower.
6. Lubricate all lubrication points. See the Main-
tenance section.
7. Be sure that all nuts, bolts and screws are
securely fastened. Inspect all visible moving
parts for damage, breakage and wear. Re-
place if necessary.
8. Cover the bare metal parts of the blower
housing and auger with spray rust preventa-
tive lubricant.
9. Put the unit in a building that has good ven-
tilation.
