Checking The Leak Detector - Toro 04510 Greensmaster 3300 TriFlex Operator's Manual

Checking the Leak Detector

The leak detector system is designed to assist in early
detection of hydraulic oil system leaks. If the oil level in the
main hydraulic reservoir, is lowered by 118-177 ml (4 to 6
ounces), the float switch in the tank will close. After a one
second delay, the alarm will sound, alerting the operator
(Figure 30). Expansion of oil, due to normal heating during
machine operation, will cause the oil to transfer into the
auxiliary oil reservoir. The oil is allowed to return to the main
tank when the ignition switch is turned off.
