2Detection circuit ..... This detects quantity of oil, sufficient or not, according to difference of electric resistance across inner and outer electrodes.

3Delay circuit ........... This his prevents the sensor from making an unnecessary stop of the engine by momentary lowering of the oil level due to the engine being slanted or affected by vibration in spite of sufficient oil in the crankcase.

4Stopping circuit ...... This automatically stops the engine running.

5-4-5 CAUTIONS TO BE TAKEN ON HANDLING THE SENSOR

(1)Oil sensor unit

1 Be sure not to damage each wire. Broken or short-circuited power supply wires and/or a ground- ing wire in particular may lead to malfunction or breakdown.

2The sensor is not interchangeable from engine to engine because the sensor is to be exclusively installed individually in each engine employed.

(2)Mounting and wiring of oil sensor unit

1 Although this has been designed to have enough antinoise properties in practical use, do not route the sensor wirings in the vicinity of noise-generating sources such as ignition plugs or high voltage cords. This may cause malfunction or breakdown.

2Since capacity of power source is limited, current flown in the electronic circuit of the sensor is kept as low as possible. Be sure to use terminals with a high contact reliability of more than that of tinned terminals.

(3)Operation of oil sensor

1 If operating with the engine kept tilted, oil surface inside of the engine varies and the correct oil level can not to be detected which in turn obstructs the preventing function of engine seizure. Operate the engine by keeping it level.

2When starting the engine with an insufficient oil in the crankcase, engine starts once then it stops automatically after it runs for 5 seconds.

3When the engine has been stopped by the oil sensor, voltage remained in the electronic circuit prevents the sensor from being restarted for 3 seconds after the engine stop. Try to restart the engine after 3 seconds or more.
