Handling and Storing Diesel Fuel
CAUTION: Handle fuel carefully. Do not fill
the fuel tank when engine is running.
DO NOT smoke while you fill the fuel tank or
service the fuel system.
Fill the fuel tank at the end of each day’s operation to
prevent water condensation and freezing during cold
weather.
Keep all storage tanks as full as practicable to
minimize condensation.
Ensure that all fuel tank caps and covers are installed
properly to prevent moisture from entering.
Monitor water content of the fuel regularly.
When using bio-diesel fuel, the fuel filter may require
more frequent replacement due to premature plugging.
Check engine oil level daily prior to starting engine. A
rising oil level may indicate fuel dilution of the engine
oil.
IMPORTANT: The fuel tank is vented through the
filler cap. If a new filler cap is
required, always replace it with an
original vented cap.
When fuel is stored for an extended period or if there
is a slow turnover of fuel, add a fuel conditioner to
stabilize the fuel and prevent water condensation.
Contact your fuel supplier for recommendations.

Testing Diesel Fuel

DIESELSCAN analysis verifies fuel type, cleanliness,
water content, suitability for cold weather operation, and
whether the fuel meets specifications.
