Check the Leak Detector
Operation
The TURF GUARDIAN™ leak detector detects
hydraulic oil system leaks. If the oil level in the main
hydraulic reservoir is lowered by 12–18 cl, the float
switch in the tank will close. After a 1-second delay,
the alarm will sound. Expansion of oil, due to normal
heating during machine operation, will cause 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.
