6. Turn key in ignition switch to the ON position. Electric
fuel pump will begin operation, thereby forcing air out
around air bleed screw. Leave key in ON position until
a solid stream of fuel flows out around screw. Tighten
screw and turn key to OFF.
Note: Normally, engine should start after 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 Injectors.

Red Diagnostic Light

The red diagnostic light (Fig. 29), located on steering
tower, is used to convey several different messages. While
starting the machine, the light will illuminate when the
glow plugs are on.
If the light blinks during operation, it may indicate any of
the following:
The machine is being operated faster than the maximum
speed value initially programmed into the ECU.
An electrical malfunction has been detected (open or
shorted output.
A hydraulic leak has been detected (Only if
Turfdefender leak detector is installed on machine)
A communications error has been detected (Only if
Turfdefender leak detector is installed on machine)

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
2–3 MPH (3–4.8 km/h) 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 top of variable
displacement pump (Fig. 30). Rotate the valve 90 , in
either direction, to open and allow oil to bypass
internally. Because fluid is bypassed, the machine can
be moved slowly without damaging the transmission.

2. Close the bypass valve before starting the engine.
However, do not exceed 5–8 ft.-lb. (7–11 N m) torque
to close the valve.
Important Running the engine with the bypass valve
open will cause the transmission to overheat.
