Starting And Stopping The Engine; Pushing Or Towing The Machine - Toro 30859N Operator's Manual

1. 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; refer to Bleeding Air from the Injectors.
Starting and Stopping the
Engine
Important: You must bleed the fuel system before
starting the engine if you are starting the engine for the
first time, the engine has stopped due to lack of fuel, or
you have performed maintenance on the fuel system;
refer to Bleeding the Fuel System.
Starting the Engine
1. Sit on the seat, keep your foot off of the traction pedal
so that it is in Neutral, engage the parking brake, set
the throttle to the Fast position, and ensure that the
Enable/Disable switch is in the Disable position.
2. Turn the ignition switch to the On/Preheat position.
An automatic timer will control the glow plug preheat
for 6 seconds.
3. After preheating the glow plugs, turn key to the Start
position.
Crank the engine for no longer than 15 seconds.
Release the key when the engine starts. If additional
Figure 18
preheating is required, turn key to the Off position and
then to the On/Preheat position. Repeat this process
as required.
4. Run the engine at low idle speed until it warms up.
Stopping the Engine
1. Move all controls to Neutral, set the parking brake,
move the throttle to the low idle position and allow the
engine to reach low idle speed.
Important: Allow the engine to idle for 5
minutes before shutting it off after a full load
operation. Failure to do so may lead to trouble on
a turbo-charged engine.
2. Turn the key to the Off position and remove it from
the switch.
Pushing or Towing the
Machine
In an emergency, the machine can be moved by actuating the
bypass valve in the variable displacement hydraulic pump and

pushing or towing the machine.

Important: Do not push or tow the machine faster than
3-4.8 km/h (2-3 mph) because internal transmission
damage may occur. The bypass valve must be open
whenever the machine is pushed or towed.
1. The bypass valve is located on the left side of the
hydrostat (Figure 19). Rotate the bolt 1–1/2 turns to
open and allow oil to bypass internally. Because fluid
is bypassed, the machine can be moved slowly without
damaging the transmission.
1. Bypass valve
2. Close the bypass valve before starting the engine.
However, do not exceed 7-11 N-m (5-8 ft.-lb) torque
to close the valve.
