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.
