Checking the Leak Detector
The leak detector system is designed to assist in early
detection of hydraulic-fluid-system leaks. If the oil level in the
main hydraulic reservoir, is lowered by 118 to 177 ml (4 to 6
oz), the float switch in the tank will close. After a 1 second
delay, the alarm will sound, alerting the operator
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.
