Gauge reading:
Lo-pressure end: 0.15~0.25 Mpa (1.5~2.5 Kgf/cm²)
Hi-pressure end: 1.37~1.57 Mpa (14~16 Kgf/cm²)
After the engine has been preheated, read the pressure value on the gauge under the following
conditions:
1) Temperature at air inlet: 30 – 35°C
2) Engine speed: 1500 rpm
3) Fan speed: High
