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 6.4 km/h (4 mph) to match the reverse
traction speed. (All 8 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 backward 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
(page
45).
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
(0.25 to 0.50 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.
1. Set the parking brake, turn the key in the ignition
switch to the O
position, park the machine on a level
FF
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
20) with a 12 mm wrench.
Adjusting the Parking Brakes
1. Bleed screw
4. Turn the key in the ignition switch to the O
The electric fuel pump will begin operation, thereby
forcing air out around the air bleed screw. Leave the
key in the O
position until a solid stream of fuel flows
N
out around the screw.
5. Tighten the screw and turn the key to the O
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 Fuel Injectors (page
41).
