Check the Torque of the Wheel
Nuts
Torque the wheel lug nuts to 94 to 122 N⋅m (70 to 90 ft-lb)
after 1-4 hours of operation and again after 10 hours of
operation. Torque every 250 hours thereafter.
WARNING
Failure to maintain proper torque of the wheel nuts
could result in personal injury.
Breaking-in the Machine
To ensure optimum performance of the parking brake
system, burnish (break-in) the brakes before use. Set the
forward traction speed to 4 mph to match the reverse traction
speed. (All eight spacers moved to the top of the mow speed
control.) With the engine at high idle, proceed forward with
the mow speed control stop engaged and ride the brake for 15
seconds. Proceed backwards at full reverse speed and ride the
brake for 15 seconds. Repeat this 5 times waiting 1 minute
between each forward and reverse cycle to avoid overheating
the brakes. An adjustment to the brakes may be required after
break-in; refer to Adjusting the Parking Brakes.
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.
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 13 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.
1. Park the machine on a level surface and ensure that the
fuel tank is at least half full.
2. Open the hood.
3. Open the air bleed screw on the fuel injection pump
(Figure 24) with a 12 mm wrench.
1. 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 the Off position.
Note: Normally, the engine should start after the above
bleeding procedures are followed. However, if engine does
not start, air may be trapped between injection pump and
injectors; refer to Bleeding Air from the Injectors.
Starting and Stopping the
Engine
Important: You must bleed the fuel system before
starting the engine if you are starting the engine for the
first time, the engine has stopped due to lack of fuel, or
you have performed maintenance on the fuel system;
refer to Bleeding the Fuel System.
Starting the Engine
1. Sit on the seat, keep your foot off of the traction pedal
so that it is in Neutral, engage the parking brake, set
the throttle to the Fast position, and ensure that the
Enable/Disable switch is in the Disable position.
2. Turn the ignition switch to the On/Preheat position.
