Safe Operation Practices for Snowthrowers
As Recommended By: American National Standards Institute.
Engine Exhaust, some of its constituents, and
certain vehicle components contain or emit
chemicals known to the State of California to
cause cancer and birth defects or other reproductive harm.
Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause
cancer and birth defects or other reproductive
harm. WASH HANDS AFTER HANDLING.
IMPORTANT: Safety standards require operator presence
controls to minimize the risk of injury. Your snowthrower is
equipped with such controls. Do not attempt to defeat the
function of the operator presence control under any circumstances.

BEFORE STARTING ENGINE
Check the oil
NOTE: The engine was shipped from the factory filled
with oil. Check the level of the oil. Add oil as needed.
1. Make sure the unit is level.
2. Remove the oil fill cap/dipstick. Check the oil.
NOTE: Do not check the level of the oil while the

on the oil fill/cap dipstick (see Figure 16). Do not add too
much oil.
NOTE: For extreme cold operating conditions of 0F
(-18 C) and below, use a synthetic 0W30 motor oil for
easier starting.
NOTE: S.A.E. 5W30 motor oil may be used to make
starting easier in areas where the temperature is 20 F.
(-7 C) to 0F (-18 C).

WARNING: Gasoline is flammable. Always use
caution when handling or storing gasoline. Do
not add gasoline to the fuel tank while snowthrower is running, hot, or when snowthrower is in an
enclosed area. Keep away from open flame, electrical
sparks and DO NOT SMOKE while filling the fuel tank.
Never fill the fuel tank completely; but fill the fuel tank
to within 1/4-1/2 inch (6.5-12.5 mm) from the top to provide space f o r t h e e x p a n s ion of the fuel. Always fill fuel
tank outdoors and use a funnel or spout to prevent spilling. Make sure to wipe up any spilled fuel before starting the engine.
Store gasoline in a clean, approved container , and keep
the cap in place on the container. Keep gasoline in a
cool well ventilated place; never in the house. Never
buy more than a 30 day supply of gasoline to assure
volatility. Gasoline Is intended to be used as a fuel for
internal combustion engines; therefore, do not use
gasoline for any other purpose. Since many children
like the smell of gasoline, keep it out of their reach because the fumes are dangerous to inhale, as well as being explosive.

FILL GAS
1. Fill the fuel tank with a fresh, clean, unleaded regular , u n leaded premium, or reformulated automotive gasoline
only. DO NOT use leaded gasoline.
NOTE: Winter grade gasoline has higher volatility to
improve starting. Be certain container is clean and
free from rust or other foreign particles. Never use
gasoline that may be stale from long periods of
storage in the container.
CAUTION: DO NOT use gasoline containing any
amount of alcohol as it can cause serious damage to
the engine or significantly reduce the performance.
2. Check to make sure that spark plug is tightened securely
into engine and spark plug wire is attached to spark plug.
If torque wrench is available, torque plug to 18-23 ft-lbs.
