Checking During Operation
If an engine abnormality is observed
during operation, stop the engine
immediately.
* Sustained use of the engine without any
remedy could cause serious personal injury or
damage to the devices.
* Investigate the cause of abnormality, correct
the defect, then restart the engine.
* If the cause of problem cannot be located,
contact your SME dealer.
If overload symptoms such as black
exhaust smoke is observed, reduce
the load immediately and assure the
proper output.
* Overload could not only cause increase in fuel
consumption but also lead to malfunction and
environmental pollution (outbreak of the black
smoke) due to carbon deposits.
Check exhaust pipes and pipe joints
for exhaust gas leaks.
* Otherwise, it may cause carbon monoxide
intoxication and lead to death at the worst.
* If an exhaust leak is found, contact your SME
dealer.
If an abnormal engine oil pressure
drop is observed, stop the engine
immediately, and check the engine oil
system to locate the cause.
* Sustained use of the engine without any
remedy could cause seizure of the bearings and
lead to serious damage to the devices.
* If the cause of problem cannot be located,
contact your SME dealer.
If a belt breaks, stop the engine
immediately and replace the belt.
* Sustained use of the engine without any
remedy could cause defective battery charge
and cooling fault, and result in serious engine
problems.
Keep the intake air temperature at
the specified level.
* If the intake air temperature is higher than the
specified level, the engine stopping device may
work due to the increased exhaust temperature
and stop the engine suddenly.
* The thermal load could increase excessively
and will cause piston scuffing.
* If the intake air temperature cannot be kept at
the specified level, reconsider the operating
conditions and operating time.
Keep the engine oil and coolant
temperatures at the specified level.
* If the engine oil or coolant temperatures is
increased, the engine stopping device may
work due to the increased exhaust temperature
and stop the engine suddenly.
