When the oil pressure switch turns on oil pressure is 150 kPa (1.5 kg/cm

, 21.3 psi) or below,
this mode starts. The buzzer will sound and the warning light will turn on. Ignition to cylinders

This mode will stop when the oil pressure is 150 kPa (1.5 kg/cm
2
, 21.3 psi) or above and the
throttle is fully closed. The buzzer will then stop and the warning light will turn off.

on the other engine, the warning light will not light and the buzzer will not sound.
