Manual Extract: Problem Symptom List
| Symptom
| Definition
| Engine start problem
| Cranking rotation is low.
Cranking rotation is normal, but the engine does not start (no initial
ignition).
Engine starts (ignition occurs), but engine rotation cannot be stabilized
and maintained. Revving also cannot be done.
| Engine stalling
| Engine cranking is done, but the engine will not start for a long time.
The engine starts after a long time or stops just after starting.
| Engine hunting, unstable idling speed
| The engine idling speed varies or the engine idling speed changes.
When the problem is severe, the engine or main unit vibrates. If any of
these states becomes severe, it may cause the engine to stall.
| Engine output deficiency
| The engine output is below what is expected, and output does not
change even if the accelerator lever (throttle lever) is raised. Responsivity
is poor
| Excessive white smoke in exhaust gas
| There is a great deal of white smoke during operation.
| Excessive black smoke in exhaust gas
| There is a great deal of black smoke during operation.
| Abnormal noise
| The engine combustion noise is abnormal.
| High fuel consumption
| Fuel consumption markedly exceeds what is listed in the Service Text.
The case indicated here shows that there is no main unit-side problem
and engine inspection is necessary.
