Fuel System
Maintenance
DANGER
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 comes

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.
