This warning light comes on with engine at rest when the ignition
circuit is operated and goes out as soon as the engine lubrica-
tion circuit is pressurized.
If this warning light remains on or comes on with the engine run-
ning, stop the machine immediately and try to locate the trouble.
If the warning light comes on together with the engine coolant
temperature warning light, the failure refers only to the engine oil
pressure.

It comes one for 3 seconds when the automatic check is operat-
ed or when the engine coolant exceeds the maximum tempera-
ture allowed; in this case, let the engine idle until it stops.
If this inconvenience occurs again, make sure that the radiator is
clean.
