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 6 to 12 mm
(1/4 to 1/2 inches) 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.
Draining the Fuel Tank
Service Interval: Every 800 hours
Before storage
Drain and clean the fuel tank if the fuel system becomes
contaminated or if the machine is to be stored for an extended
period. Use clean fuel to flush out the tank.
Checking the Fuel Lines and
Connections
Service Interval: Every 400 hours/Yearly (whichever comes
first)
Check the fuel lines and connections. Inspect them for
deterioration, damage, or loose connections.
Bleeding the Fuel System
You must bleed the fuel system before starting the engine if
any of the following situations have occurred:
•
Initial start up of a new machine.
•
Engine has ceased running due to lack of fuel.
•
Maintenance has been performed upon fuel system
components; i.e., filter replaced, separator serviced, etc.

1. Park the machine on a level surface and ensure that the
fuel tank is at least half full.
2. Open the hood.
3. Turn the key in the ignition switch to the O
and crank the engine.
Note: The mechanical pump will suck fuel out of the
tank, fill the fuel filter and fuel hose, and force the air
into the engine. This could take some time to fully
purge all the air out of the system and the engine might
fire erratically until all air is purged out. When all air is
purged and the engine is running smoothly, it should be
run for a few minutes to ensure that it is fully purged.
Replacing the Fuel Filter
Service Interval: Every 400 hours
Important: Replace the fuel filter canister periodically
to prevent wear of the fuel injection pump plunger or the
injection nozzle, due to dirt in the fuel.
1. Place a clean container under the fuel filter canister
(Figure
43).
2. Clean the area where the filter canister mounts.
