Lubrication System
Oil Level Sensor Switch
If the oil level becomes lower than the preset value, the sensor switch
[A] closes. As a result, the base current [IB1] passes through the Zener
diode [Z1] and the resistor [R12] to flow to [TR1] to maintain the circuit.
The base current [IB1] is held by the amplified collector current [IC1],
and as a result, the spark current does not generate, causing the engine
to stop. (Refer to the section on Ignition System for comparison.)
A: Oil Level Sensor Switch
ESW: Engine Switch
Inspection method
Verify that the oil level of the engine is normal.
Disconnect the wire from the oil level sensor terminal.
Set the measurement range of the tester to R 1 and connect one
of the tester leads to the terminal of the sensor and the other end to
ground. The tester should read .
If the tester does not read , the oil level sensor switch is faulty.
Gently lift the PTO side to tilt the engine.
