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. 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:
• 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 Checking
Oil Level in Engine Maintenance (page 35)

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, lefthand location. To use the right
side fuel tank rotate the fuel selector valve to the RH,
righthand location (Figure 7)
Close the fuel selector valve before transporting or
storing machine.
