DANGER
Amputation hazard
The discharge chute contains a rotating impeller to throw
snow. Fingers can quickly become caught and traumatic
amputation or severe laceration will result. Hand contact
with the rotating impeller inside the discharge chute is the
most common cause of injury associated with snowthrowers.
Turn the engine OFF, wait for all moving parts to stop, and

The discharge chute contains a rotating impeller to throw
snow. Fingers can quickly become caught and traumatic
amputation or severe laceration will result. Hand contact
with the rotating impeller inside the discharge chute is the
most common cause of injury associated with snowthrowers.
Turn the engine OFF, wait for all moving parts to stop, and
remove the engine key before performing any maintenance
or repairs.

sion and/or fire may result.
Handle gasoline carefully. Never store the unit, with fuel in
the tank, indoors or in a poorly ventilated enclosure where
fuel fumes could reach an open flame, spark, pilot light,
such as a furnace, water heater, or clothes dryer.
Equipment
• Thoroughly clean the unit.
Ʒ ˸ȿ¹·Ê»Ê¾»¾»Îɾ·¼ÊƺÉ»»Maintenance section).
• Make sure all nuts, bolts, and screws are securely fastened. Inspect all visible moving parts for damage, breakage, and wear. Replace if necessary.
• Apply a rust preventative to any bare metal parts of the
snowthrower auger and impeller.
• If possible, store the unit indoors and cover it to give protection from dust and dirt.
• If the machine must be stored outdoors, cover it with a
heavy tarpaulin.
Fuel System
Fuel can become stale when stored over 30 days. Stale fuel
causes acid and gum deposits to form in the fuel system or
on essential carburetor parts. To keep fuel fresh, use Briggs
& Stratton® Advanced Formula Fuel Treatment & Stabilizer, available wherever Briggs & Stratton genuine service
parts are sold.
There is no need to drain gasoline from the engine if a fuel
stabilizer is added according to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the
fuel system before storage. If gasoline in the engine has not
been treated with a fuel stabilizer, it must be drained into an
approved container. Run the engine until it stops from lack
of fuel. The use of a fuel stabilizer in the storage container is
recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil. See
Changing the Oil in the engine operator’s manual.
