starts. The key will move automatically to the
On/Run position.
Important: To prevent overheating of the
starter motor, do not engage the starter longer
than 15 seconds. After 10 seconds of continuous
cranking, wait 60 seconds before engaging the
starter motor again.
5. When the engine is started for the first time or after
an overhaul of the engine, operate the machine in
forward and reverse for one to two minutes. Also
operate the lift lever and cutting unit drive switch to
be sure of proper operation of all parts.
Turn the steering wheel to the left and right to
check steering response; then shut the engine off
and check for oil leaks, loose parts, and any other
noticeable malfunctions.
CAUTION
Stop the engine and wait for all moving parts to
stop before checking for oil leaks, loose parts,
and other malfunctions.
Stopping the Engine
Move the throttle control to the Idle position, move the
cutting unit drive switch to Disengage, and rotate the
starter key to Off. Remove the key from the switch to
prevent accidental starting.

Bleeding the Fuel System

1. Park the machine on a level surface. Make sure that
the fuel tank is at least half full.
2. Unlatch and raise the hood.
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 inch (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.
3. Open the air bleed screw on the fuel injection pump
(Figure 26).
1. Fuel injection pump bleed screw
4. Turn the key in the ignition switch to the On
position. The electric fuel pump will begin
operation, thereby forcing air out around the air
bleed screw. Leave the key in the On position until
a solid stream of fuel flows out around the screw.
5. Tighten the screw and turn the key to Off.
Note: Normally the engine should start after the
above bleeding procedures are followed. However, if
the engine does not start, air may be trapped between
the injection pump and injectors; refer to Bleeding Air
from the Injectors.
