Engine - Engine and Mounting
The injector performs four functions:
a - Creates the high fuel pressure required for efficient
injection.
b - Meters and injects the exact amount of fuel
required to handle the load.
c - Atomizes the fuel for mixing with the air in the
combustion chamber.
d - Permits continuous fuel flow for component cooling.
Electronic fuel system injectors are self compensating
and virtually eliminate engine tune-ups.
Note: Never apply 12 V directly to terminals on the
injector or engine sensors as they will burn out. Before
removing injectors, the fuel passages must be blown
out to prevent fuel flow from entering the cylinder
head.
4. Batteries - Two 12 volt maintenance free batteries
supply the machine with electrical power to operate all
electrical components.
5. Electronic Foot Pedals - The electronic foot pedals
provide an electrical signal to the engine's fuel control
system in proportion to the degree of pedal actuation.
Note: The HEUI controlled engine will override the
electronic foot pedal position until the engine is
warmed up to the correct operating temperature. The
engine MUST be started with foot 'OFF' the electronic
foot pedal.
6. Stop Engine Light - When the 'Stop Engine' light
comes on, the computer has detected a major
malfunction in the engine that requires immediate
attention. It is the operators responsibility to shut down
the engine to avoid serious damage.
7. Check Engine Light - When the 'Check Engine'
light comes on, the computer has detected a fault in
the engine. The fault should be diagnosed and
corrected at the earliest opportunity.
