contact your MHIET dealer.
If overload symptoms such as black
exhaust smoke is observed, reduce
the load immediately and assure the
proper output.
* Overload may not only cause increase in fuel
consumption but also lead to malfunction and

* 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.
