The function of the low oil unit is to prevent the engine from running
after startup if the engine is low on oil.
To test the low oil unit:
Remove the lower engine guard (a).
Lay the machine down and remove the low oil unit (b) from the
crankcase.
Disconnect the wiring from the engine to the low oil unit.
Attach a 9V battery to the low oil unit as shown. A functioning low oil
unit should flash at a steady rate.
• If the low oil unit does not flash at a steady rate, it has failed;
replace it.
• If the low oil unit does flash at a steady rate, continue.
Grasp the sensors (c) with your fingertips. This action will change the
capacitance of the sensors, and will change the flashing action (duty
cycle) of the low oil unit from a period where the light remains on longer
than it is off, to one where the light is off longer than it is on.
• If the low oil unit performs accordingly, it is functioning properly.
• If the low oil unit does not perform accordingly, it has failed;
replace it.
