[5] OIL SIGNAL

[6] OIL PRESSURE SWITCH

The oil signal is mounted to the cylinder block to
warn the operator that the lubricating oil pressure is poor.
At engine stop and at unusually low pressure (Less
than 50 kPa, 0.5 kgf/cm
displayed.
When the oil pressure is normal (50 kPa,
2
0.5 kgf/cm , 7 psi or more), the blue signal (1) is pushed
out by means of the oil pressure.
(1) Blue Signal
(2) Red Indication
While oil pressure is high and the force applied to the
diaphragm (2) is larger than the spring tension, the
terminal contact (3) is separated from the body contact
(4).
If the pressure drops below 50 kPa (0.5 kgf/cm
7 psi), the contact closes.
