engine.
Most failures give some kind of early

in performance, sound or engine
C
appearance that can indicate service
or engine repair is needed. Some
changes to look and/or listen for:
• Engine misfires
• Loss of power
• Sudden changes in engine operating temperature or oil pressure
• Excessive smoke
• Fuel, oil or coolant leaks
• Vibration
• Increased oil or fuel consumption
Excessive full throttle operation below peak torque RPM will shorten
engine life to overhaul and can cause serious engine damage. Operation
of the engine below peak torque RPM can occur during gear shifting due
to difference of gear ratios.
Engine shutdown system (if equipped)
This system is designed to help prevent engine damage that could result
from operating the engine during a prolonged period of low engine oil
pressure, high engine coolant temperature or low coolant level. If any of
these conditions occur, a warning light will illuminate and a chime will
sound warning the operator that the engine will shutdown in 30 seconds.
This is to allow time for the operator to move the vehicle off the road. If
additional time is required, the engine can be restarted and run each
time for approximately 30 seconds.
Do not attempt to use this restarting feature to drive the vehicle, serious
engine damage could result.
