Operating the Leak Detector
The leak detector alarm may sound for one of the following
reasons:
•
A leak of 118 to 177 ml (4 to 6 oz) has occurred.
•
The oil level in the main reservoir is reduced by 118 to
177 ml (4 to 6 oz) due to contraction of the oil by cooling.
If the alarm sounds, turn off the machine as quickly as
possible and inspect it for leaks. If the alarm sounds while
operating on a green, drive off the green first. Determine the
source of the leak and repair it before continuing operation.
If you do not find a leak and suspect a false alarm, move the
ignition switch to the O
stand for 1 to 2 minutes to allow the oil levels to stabilize.
Then start the machine and operate it in a non-sensitive area
to confirm that no leak exists.
False alarms, due to oil contraction, may be caused by
extended idling of the machine after normal operation. A
false alarm may also occur if you work the machine at a
reduced workload after an extended period of a heavier
workload. To avoid false alarms, turn the machine off rather
than idling for extended periods.
