Using Biodiesel Fuel
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 must meet specification
ASTM D6751 or EN14214.
The blended fuel composition should meet ASTM D975
or EN590.
Biodiesel blends may damage painted surfaces.
Use B5 with a biodiesel content of 5% or less in cold
weather.
Check seals, hoses, and gaskets that come in contact with
the fuel, as they may degrade over time.
The fuel filter may become plugged for a time after
converting to a biodiesel fuel blend.
Contact your distributor for more information about
biodiesel fuel.
Storing Fuel
If you store fuel in a storage tank, it can accumulate foreign
material or water. Keep the fuel storage tank outside, and
keep the fuel as cool as possible. Remove water from the fuel
in the storage container at regular intervals.
Filling the Fuel Tank
Note: Fill the fuel tank of the machine at the end of each day
to prevent condensation in the fuel tank.
1. Clean around the fuel-tank cap
