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 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.

water and sediment from the fuel filter
(Figure
2. Primary fuel filter
(Figure 126).
Note: If the fuel-water separator has any water or
sediment, also drain the water and sediment from
the fuel tank; refer to
Tank (page 90).
5. When clean fuel appears, rotate the drain valve
clockwise until it is closed.
Note: Do not overtighten the drain valve.
6. Prime the fuel system; refer to
System (page 91).
Draining Water from the Fuel
Tank
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Place a drain pan under the drain plug in the fuel tank.
3. Loosen the drain plug until the water and sediment
drain out (Figure

2. Drain plug
4. Clean the threads on the drain plug and apply 3 layers
of PTFE sealing tape.
5. Clean the O-ring if it comes out.
6. When clean fuel appears, install the O-ring and drain
plug, and tighten the plug securely.
7. Check the fuel-tank drain plug for leaks.
