5.Low noise and less vibration
Low noise (Reduced by 9dB*) and less vibration does not interfere with speech communication during

*Numerical data are comparison with our two stroke models operating at 0.4MPa.

6.Excellent fuel economy
Electrically controlled fuel injection helps optimum fuel supply depending on engine speed,
maximizing lower fuel consumption.

7.Engine overheat protection sensor
Engine overheat protection device is provided to safeguard against cooling water loss, and to protect
engine in the operation with discharge valve closed. This device automatically shuts off engine when
engine temperature reaches 80℃.

8.Electrically controlled fuel injection
Electrically controlled fuel injection secures reliable engine starting under any weather condition even
in the event of low battery power.

9.Auto priming system
