3.2.1.1 EMERGENCY WARNING LIGHTS
CAUTION
q
If a warning light comes on or the acoustic alarm sounds while the engine is running, stop the engine
immediately and try to locate the cause of the failure.
These warning lights must always be checked while the engine is running. If any anomaly occurs, the warning light
corresponding to the faulty function comes on and the acoustic alarm starts sounding. Carry out the necessary re-
pairs immediately.
1. Engine oil pressure warning light
This warning light comes on, together with the acoustic alarm,
when the engine is not running and the starting circuit is operated,
and goes out as soon as the engine lubrication circuit is pressu-
rized.
If it does not go out or comes on when the engine is running, stop
the machine immediately and try to find the cause of the failure,
see ( "3.7.6 OTHER TROUBLES").
