DANGER
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 on level ground, 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. Fill
the fuel tank to the bottom of the filler neck.
The empty space in the tank allows gasoline to
expand. Overfilling may result in fuel leakage
or damage to the engine or emission system (if
equipped).
• 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. Do not 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:
•
The biodiesel portion of the fuel meet specification
ASTM D6751 or EN14214.
•
The blended fuel composition should meet ASTM D975
or EN590.
•
Painted surfaces may be damaged by biodiesel blends.
•
Use B5 (biodiesel contend of 5%) or lesser blend in cold
weather.
•
Monitor seals, hoses, gaskets in contact with fuel as they
may be degrade over time.
•
Fuel filter plugging maybe expected for a time after
converting to biodiesel blends.
•
Contact your distributor if you wish for more information
on biodiesel.

Filling the Fuel Tank

Note: Do not fill the fuel tank completely full. Fill the fuel
tank to the bottom of the filler neck. The empty space in the
tank allows the gasoline to expand.
1. Shut the engine off and set the parking brake.
2. Clean around each fuel tank cap and remove the cap.
Fill the fuel tank to the bottom of the filler neck. This
space in the tank allows the fuel to expand. Do not fill
the fuel tank completely full.
3. Install the fuel tank cap securely. Wipe up any fuel that
may have spilled.
4. If possible, fill the fuel tank after each use. This will
minimize possible buildup of condensation inside the
fuel tank.

Checking the Engine-Oil Level

Before you start the engine and use the machine, check
the oil level in the engine crankcase; refer to
Engine-Oil Level (page

Switching the Fuel Tanks

Important: Do not run the machine out of fuel. This
may cause engine damage and require the fuel system
to be checked.
The fuel-selector valve is located behind the left side of the
seat.
The unit has two fuel tanks. One tank is on the left side and
one on the right side. Each tank connects to the fuel-selector
valve. From there a common fuel line leads to the engine
(Figure 7).
To use the left side fuel tank rotate the fuel-selector valve to
the LH, left-hand location. To use the right side fuel tank
rotate the fuel-selector valve to the RH, right-hand location
(Figure 7).
Close the fuel-selector valve before transporting or storing
the machine.
