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

F. Close the top coolant bleed valve (Figure 21).
G. Pour coolant into the coolant filler neck until the
coolant level comes into the filler neck (Figure 21).
H. Install the coolant fill cap (Figure 21).
I. Add coolant into the expansion tank until it
reaches the Full line on the side of the tank
(Figure 21).
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).
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.
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 22).
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 between
attempts. Failure to follow these instructions can
burn out the starter motor.
6. Move the throttle lever to desired setting.
Important: If the engine is run at high speeds
when the hydraulic system is cold (i.e., when the
ambient air temperature is near freezing or lower),
