Servicing the Fuel System

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 25 mm (1 inch)
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.
Fuel Tank
Service Interval: Every 1,000 hours—Drain and clean the
fuel tank.
Drain and clean the fuel tank every 1000 hours. Also, drain
and clean the tank if 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.
Fuel Lines and Connections
Service Interval: Every 500 hours—Inspect the fuel lines
and connections.
Check the fuel lines and connections every 500 hours or
yearly, whichever comes first. Inspect them for deterioration,
damage, or loose connections.

Servicing the Water Separator

Service Interval: Before each use or daily—Drain the water
separator
Every 500 hours—Replace the fuel/water separator
element.
Draining the Water Separator
1. Place a clean container under the water separator
(Figure 64).
