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 octane 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.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
