Operation
NOTE: Determine the left and right sides of the machine
from the normal operating position.
• Gasoline is extremely flammable and explosive.
A fire or explosion from gasoline can burn you
and others.
• To prevent a static charge from igniting the gaso-
line, place the container and/or snowthrower on
the ground before filling, not in a vehicle or on
an object.
• Fill the tank outdoors when the engine is cold.
Wipe up spills.
• Do not handle gasoline when smoking or around
an open flame or sparks.
• Store gasoline in an approved fuel container, out
of the reach of children.
• Do not tip the snowthrower with fuel in the fuel
tank.
The operation of any snow thrower can result
in foreign objects thrown into the eyes, which
can result in severe eye damage. Always wear
safety glasses or eye shields while operating
your snow thrower or performing any ad just-
ments or repairs. We recommend standard safe ty glasses
or a wide vision safety mask worn over spectacles.
IMPORTANT: Know how to operate all controls before
adding fuel or attempting to start the engine.
Filling the Fuel Tank
Fill the fuel tank with fresh unleaded gasoline, do not
exceed 87 octane rating (Figure 8).
IMPORTANT: Do not add oil to the gasoline.
IMPORTANT: Do not use E85 blended fuels. This engine
is not E20/E30/E85 compatible. Alternative fuels with
high alcohol content can cause hard starting, poor engine
performance, and may cause internal engine damage.
Checking the Engine Oil
Level
NOTE: 10W30 synthetic oil is acceptable for use in cold
temperatures.
1. Move the snowthrower to a level surface.
2. Clean around the dipstick (Figure 9).
NOTE: Dipstick location may vary depending on engine
type.
3. Remove either side mounted filler cap dipstick or high
oil fill dipstick and wipe it clean.
4. Insert the dipstick into the filler neck and turn clockwise
until fully seated. Then remove the dipstick by turning
it counter-clockwise.
5. Fill oil to "FULL" on dipstick with the recommended oil.
6. Securely screw in the oil filler cap/dipstick.
NOTE: Running the engine with a low oil level can cause
engine damage. Always check the engine oil before start up.
NOTE: Running the engine with too much oil may cause
engine damage and excess smoke in the exhaust. Always
check the engine oil level before start up.
NOTE: For best results, purchase only the quantity of
gasoline that you expect to use in 30 days. Otherwise,
you may add fuel stabilizer to newly purchased gasoline
to keep it fresh for up to 6 months.
