Fuel System
Maintenance
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A
fire or explosion from fuel can burn you and
others and can cause property damage.
• Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is off and
is cold. Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add
fuel to the fuel tank until the level is 1/4 to
1/2 in. (6 to 13 mm) below the bottom of
the filler neck. This empty space in the tank
allows the fuel to expand.
• 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 a clean, safety-approved
container and keep the cap in place.
Checking the Fuel Lines and
Connections
Service Interval: Every 400 hours/Yearly (whichever

Inspect the fuel lines and connections for deterioration,
damage, or loose connections. Tighten any loose
connections and contact your Authorized Service Dealer
for assistance in fixing damaged fuel lines.
