Before Starting
Engines which are certified to comply with California
and U.S. EPA emission regulations for ULGE engines:
Are certified to operate on regular unleaded gasoline/oil
mix. Include the following emission control system(s):
EM, TWC (if so equipped); Do not include any user
adjustable features— therefore no other adjustments are
needed.
Mixing Gasoline and Oil
Use only clean, fresh, lead-free gasoline (including
oxygenated or reformulated gasoline) with an octane
rating of 87 or higher. To ensure freshness, purchase only
the quantity of gasoline you expect to use in 30 days.
Using unleaded gasoline results in fewer combustion
chamber deposits and longer spark plug life.
IMPORTANT: Do not use methanol, gasoline
containing methanol, gasohol containing mmore than
10% ethanol, premium gasoline, or white gas. Using
these fuels can damage the engine’s fuel system.
IMPORTANT: Do not use automotive oil (i.e., SAE 30,
10W30, etc.), a two–cycle oil that is not NMMA– or
TCW–certified, or a fuel mixed at the wrong
gasoline/oil ratio. This can cause engine damage not
covered under the Lawn-Boy warranty.
DANGER
POTENTIAL HAZARD
•
In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
•
A fire or explosion from gasoline can burn you,
others, and cause property damage.
HOW TO AVOID THE HAZARD
•
Use a funnel and fill the fuel tank outdoors, in
an open area, 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” (6 mm to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
gasoline to expand.
•
Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
•
Store gasoline in an approved container and
keep it out of the reach of children.
•
Never buy more than a 30-day supply of
gasoline.
DANGER
POTENTIAL HAZARD
•
When fueling, under certain circumstances, a
static charge can develop, igniting the gasoline.
WHAT CAN HAPPEN
•
A fire or explosion from gasoline can burn you
and others and cause property damage.
HOW TO AVOID THE HAZARD
•
Always place gasoline containers on the ground
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 gas–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, rather than from a gasoline
dispenser nozzle.
•
If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.
1. Pour a half gallon of gasoline into an approved
gasoline 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 proper amount of high–grade, NMMA– or
TCW–certified two-cycle oil to acheive a 32:1
gasoline–to–oil mixture ratio. Refer to the following
table:
32:1 Gasoline-to-Oil Mixture Ratio
4 oz. (0.118L) can
8 oz. (0.236L) can
20 oz. (0.590L) bottle
Oil
Gasoline
1 gallon (3.75L)
2 gallons (3.75L)
5 gallons (3.75L)
For best results, use Lawn-Boy 2-Cycle Generation II
Ashless Oil.
3. Install the cap on the gasoline container and shake the
container to mix oil and gas thoroughly.
4. Remove the cap and add the remaining gasoline.
