Fuel System
Maintenance
DANGER
Under certain conditions, diesel fuel and fuel vapors
are highly flammable and explosive. A fire or an
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 in. (25 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.

Servicing the Fuel Tank

Service Interval: Every 2 years—Drain and clean the
fuel tank.
Drain and clean the tank if the fuel system becomes
contaminated or if the machine will be stored for an
extended period of time. Use clean fuel to flush out
the tank.
Inspecting the Fuel Lines and
Connections
Service Interval: Every 400 hours/Yearly (whichever
comes first)
Inspect the fuel lines and connections for deterioration,
damage, or loose connections.

Draining the Water Separator
