The oil sensor mainly functions to detect position of the surface of engine oil in the crankcase engines for general use and to stop the engine automatically when the oil level goes down below the lower limit specified. This prevents seizure of engine from occurring due

[Judgement

When sufficient oil is in the crankcase, both of inner and outer electrodes are immersed in the oil through which current flows across the electrodes.

[Decision

Oil level at the electrodes may go by vibration even if a sufficient oil is in the crankcase. For that reason, the sensor has an electronic timer circuit to prevent it from interpreting as short of oil when amount of oil is sufficient.

Generally, the power rating of an electrical appliance indicates the amount of work that can be done by it. The electric power required for operating an electrical appliance is not always equal to the output wattage of the appliance.

generator can be reassembled correctly.. Tag the disassembled part with the necessary information to

facilitate easier and smoother reassembling.

2)

For more convenience, divide the parts into several groups and store them in boxes.

3)

To

prevent bolts and nuts from being misplaced or installed incorrectly, place them temporarily back

at their original position.

4)

Handle disassembled parts with care; clean them before reassembly using a neutral cleaning fluid.

5)

Use all disassembly /assembly tools properly, and use the proper tool for each specific job.
