Bleeding Air From The Injectors; Draining The Fuel Filter/Water Separator - Toro 41582 Operator's Manual

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 inch
(25 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, approved fuel container
and keep the cap in place.
3. Open the vent plug on the fuel/water separator
(Figure 43)

4. Turn the key in the ignition switch to the On
position.
Note: The electric fuel pump will begin forcing air
out around the air bleed screw.
5. Leave key in the On position until a solid stream of
fuel flows out around the screw.
6. Tighten screw and turn the key to the Off position.

7. Open the air bleed screw on the fuel injection pump
(Figure 44).

8. Turn key in ignition switch to the On position.
Note: Electric fuel pump will begin operation,
thereby forcing air out around air bleed screw on
fuel injection pump.
9. Leave the key in the On position until a solid stream
of fuel flows out around the screw.
10. Tighten the screw and turn the key to the Off
position.
Note: Normally, the engine should start after you bleed
the fuel system. However, if the engine does not start,
there may be air trapped between the injection pump
and the injectors; refer to Bleeding the Air from the
Injectors.

Bleeding Air from the Injectors

You should perform this procedure only after you have
purged the air in the system while you prime the engine
and it does not start. Refer to Bleeding the System
1. Loosen the pipe connection to the No. 1 nozzle and
holder assembly.
2. Move the throttle to the Fast position.
3. Turn the key in the key switch to the Start position
and watch the fuel flow around the connector. Turn
the key to the Off position when you observe a solid
flow of fuel.
4. Tighten the pipe connector securely.
5. Repeat this procedure for the remaining nozzles.
