DIESEL FUEL SYSTEM
Use No. 2 diesel fuel in the engine of this machine.
The use of other fuels can cause the loss of engine
power and high fuel consumption.
In very cold temperatures, a mixture of No. 1 and No.
2 diesel fuels is temporarily permitted. See the
following:
NOTE: See your fuel dealer for winter fuel
requirements in your area. If the temperature of the
fuel lowers below the cloud point (wax appearance
point), wax crystals in the fuel will restrict the fuel
filter and cause the engine to loose power or not
start.
The diesel fuel used in this machine must meet the
specifications below, “Specifications for Acceptable
No. 2 Diesel Fuel” or Specification D975-81 of the
American Society for Testing and Materials.
Fuel Storage
If you keep fuel in storage for a period of time, you
can get foreign material or water in the fuel storage
tank. Many engine problems are caused by water in
the fuel.
Keep the fuel storage tank outside and keep the fuel
as cool as possible. Remove water from the storage
container at regular periods of time.
Fill the fuel tank at the end of the daily operating
period to prevent condensation in the fuel tank.
