Before Starting
Mixing Gasoline and Oil
Your Lawn-Boy snowthrower is powered by a 2-cycle
engine that requires a 50:1 gasoline-to-oil mixture.
Use only clean, unleaded gasoline no more than 30 days
old and with an octane rating of 87 or higher. Using
unleaded gasoline reduces combustion chamber deposits
and promotes longer spark plug life.
Engines certified to comply with U.S. EPA emission
regulations for ULGE engines are certified to operate on a
mixture of regular unleaded gasoline and oil, include the
following emission control system(s): EM and TWC (if
equipped), and do not include any user-adjustable
features.
Important
Do not use methanol, gasoline containing
methanol, gasohol containing more than 10% ethanol,
premium gasoline, or white gas. Using these fuels can
damage the fuel system.
Important
Do not use an automotive oil (such as SAE
30 or 10W30), a 2-cycle oil that is not NMMA
TCW-certified, or a fuel mixed at the wrong
gasoline-to-oil ratio. This can cause engine damage not
covered under the Lawn-Boy warranty.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
•
Fill the fuel tank outdoors, in an open area, and
when the engine is cold. Wipe up any gasoline
that spills.
•
Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to
1/2 in. (6 to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
the gasoline to expand.
•
Never smoke when handling gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
•
Store gasoline in an approved fuel container
and keep it out of the reach of children.
•
Never buy more than a 30-day supply of
gasoline.
Danger
When fueling, under certain circumstances, a
static charge can develop, igniting the gasoline. A
fire or explosion from gasoline can burn you and
others and damage property.
•
Always place gasoline containers on the ground
and away from your vehicle before filling.
•
Do not fill gasoline containers inside a vehicle
or on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
•
When practical, remove gasoline-powered
equipment from the truck or trailer and refuel
the equipment with its wheels on the ground.
•
If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, not from a gasoline dispenser nozzle.
•
If you must use a gasoline dispenser nozzle,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.
Note: Use a fuel stabilizer/conditioner for all Lawn-Boy
gasoline-powered products during operation and storage.
A fuel stabilizer/conditioner cleans the engine during
operation and prevents gum-like varnish deposits from
forming in the engine during storage. A fuel
stabilizer/conditioner works best when you mix it with
fresh gasoline. If you use Lawn-Boy Generation II 2-Cycle
Oil (Fuel Stabilizer Added), you do not need to add a fuel
stabilizer/conditioner .
Important
Do not use fuel additives except a fuel
stabilizer during storage. Do not use fuel stabilizers with
an alcohol base, such as ethanol, methanol, or
isopropanol.
1. Pour a half gallon (1.9 liters) of fresh, unleaded
gasoline into an approved fuel container.
Note: Do not mix gasoline and oil in the fuel tank. Oil at
room temperature mixes easier and more thoroughly than
cold oil. Oil below 32
°
F (0
°
C) requires additional mixing.
2. Add the full amount of Lawn-Boy Generation II
2-Cycle Oil (Fuel Stabilizer Added) or an equivalent
high grade, NMMA TCW-certified 2-cycle oil to the
gasoline according to the chart below:
