with the Turf Guardian
Greensmaster 3400 machines, the Leak Detector Sys-
tem is optional.
Before Start-Up (Cold Oil)
With ignition switch OFF, solenoid valve is open. Before
start-up, hydraulic fluid is at level mark of sight gauge (oil
cold). Oil level sensor float is in raised position, keeping
alarm circuit open.
Normal Operation (Warm Oil)
When ignition switch is turned ON, solenoid valve
closes. During normal operation, hydraulic fluid ex-
pands, causing it to overflow into leak detector tank. The
oil level sensor stays in the raised position keeping
alarm circuit open.
