Bleeding The Fuel System - Toro 30826 Operator's Manual

1. Be sure that the parking brake is set and the deck drive
switch is in the Disengage position.
2. Remove your foot from the traction pedal and make
sure that the pedal is in the neutral position.
3. Move the throttle lever to the 1/2 throttle position.
4. Insert the key into the switch and rotate it to the
On/Preheat position until the glow plug indicator light
goes out (approximately 7 seconds); then rotate the key
to the Start position to engage the starter motor. Release
the key when the engine 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 deck 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
Shut the engine off and wait for all moving parts to
stop before checking for oil leaks, loose parts, and
other malfunctions.
6. To stop the engine, move the throttle control to the Idle
position, move the deck 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.
3. Open the air bleed screw on the fuel injection pump
(Fig. 20).
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. 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, page 36.
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 in. (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.
