Testing the Float Switch
Background
The function of the float switch is to prevent the engine from running without oil in
the oil tank. If the oil tank is low on oil, the float switch opens and prevents ignition.
A severed float switch wire will also prevent ignition. In the event that the engine
runs but shuts off by itself within approximately 25 seconds, even with oil in the oil
tank, the float switch could be faulty.
■ Machine shut down and cool
Requirements
■ Multimeter
■ Oil tank at least 1/4 full
■ Torque wrench
■ Loctite® 243
