Operation

Note: Determine the left and right sides of the
machine from the normal operating position.

Adding Fuel

The engine runs on clean, fresh diesel fuel with
a minimum cetane rating of 40. Purchase fuel in
quantities that can be used within 30 days to ensure
fuel freshness.
Use summer grade diesel fuel (No. 2-D) at temperatures
above 20° F (-7° C) and winter grade diesel fuel (No.
1-D or No. 1-D/2-D blend) below 20° F (-7° C). Use of
winter grade diesel fuel at lower temperatures provides
lower flash point and pour point characteristics,
therefore easing startability and lessening chances
of chemical separation of the fuel due to lower
temperatures (wax appearance, which may plug filters).
Use of summer grade diesel fuel above 20° F (-7° C) will
contribute toward longer life of the pump components.
Important: Do not use kerosene or gasoline
instead of diesel fuel. Failure to observe this
caution will damage the engine.
Fuel is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep gas away from eyes and skin.
In certain conditions, fuel is extremely
flammable and highly explosive. A fire or
explosion from fuel can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any fuel
that spills.
• Never fill the fuel tank inside an enclosed
trailer.
• Do not fill the fuel tank completely full. Add
fuel to the fuel tank until the level is 1/4 to
1/2 inch (6 to 13 mm) below the bottom of
the filler neck. This empty space in the tank
allows fuel to expand.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel
fumes may be ignited by a spark.
• Store fuel in an approved container and keep
it out of the reach of children. Never buy
more than a 30-day supply of fuel.
• Always place fuel containers on the ground
away from your vehicle before filling.
• Do not fill fuel 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 fuel
dispenser nozzle.
• If a fuel 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.

Biodiesel Ready

This machine can also use a biodiesel blended fuel
of up to B20 (20% biodiesel, 80% petrodiesel). The
petrodiesel portion should be low or ultra low sulfur.
Observe the following precautions:
