Bleeding The Fuel System; Starting And Stopping The Engine - Toro 22323 Operator's Manual

F. Close the top coolant bleed valve (Figure 20).
G. Pour coolant into the coolant filler neck until
the coolant level comes into the filler neck
(Figure 20).
H. Install the coolant fill cap (Figure 20).
I. Add coolant into the expansion tank until it
reaches the Full line on the side of the tank
(Figure 20).
3. Install the expansion tank cap.

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 (e.g., filter replaced).
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.
1. 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 21).
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 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; contact your Authorized
Service Dealer.
Starting and Stopping the
Engine
Starting the Engine
1. Ensure that the auxiliary hydraulics lever is in
neutral.
2. Move the throttle lever midway between slow
(turtle) and fast (rabbit) positions.
3. Turn the ignition key to the Run position.
4. Press the glow plug switch and hold it for 10
seconds.
5. Turn the ignition key to the Start position. When
the engines starts, release the key.
Important: Do not engage the starter for more
than 10 seconds at a time. If the engine fails
to start, allow a 30 second cool-down period
