3.11 Engine
3.11.1 Accelerator pedal
The accelerator pedal provides an electrical
signal to the engine's fuel control system in
proportion to the degree of pedal actuation.
(see Fig3-12).
Note:
The electronically controlled engine
will override the accelerator pedal position
until the engine is warmed up to the correct
operating temperature. The engine MUST be
started with foot 'OFF' the accelerator pedal.
This machine is equipped with the Quantum
Electronic Fuel System, an electronic engine
control system, which continually monitors
the engine and warns the operator when a
problem develops. The system also takes
action to prevent damage to the engine and,
provides the serviceman with diagnostic
capabilities so that problems can be corrected
quickly and easily.
