Turf Guardiant Leak Detector System Operation

Before Start-Up (Cold Oil)
With ignition switch in the OFF position, solenoid valve
is open. Before start-up, hydraulic fluid is at level mark
of sight gauge (oil cold). Float is in raised position, keep-
ing alarm circuit open.
Normal Operation (Warm Oil)
When ignition switch is turned to the RUN position, sole-
noid valve closes. During normal operation, hydraulic
fluid expands, causing it to overflow into auxiliary tank.
The float stays in the raised position keeping alarm cir-
cuit open.
Leak Alert!
If hydraulic fluid leaks during operation, the fluid level in
the main hydraulic tank drops. This causes the float to
lower, closing the alarm circuit. The alarm will sound af-
ter a one second time delay.
NOTE: During normal operation, with cutting units low-
ered, approximately 5 oz (148 ml) of hydraulic fluid will
leak before the float closes the alarm circuit and acti-
vates the alarm.
