Toro Reelmaster 6500-D Service Manual page 150

Note: If machine must be operable with leak detector
disabled, unplug leak detector 4--pin connector from
4--pin connector of main harness. Do not unplug leak
detector alarm.
If false alarms are observed:
1. Oil level may be low causing air to be drawn out of
system. Check oil level.
2. Extremely hard left turns can cause oil to slosh to the
right, exposing suction line and purging air out of sys-
tem. Normal maneuvering should not cause this condi-
tion.
3. Air leak in system. Check to make sure cap is secure-
ly on tank. Contact your local authorized Toro Distributor
for further assistance with air leak problem.
4. To check for a system problem, install hand held
Diagnostic ACE, toggle input/output and check for any
problems previously discussed.

Note: The system will reset itself whenever the
ignition key is turned to "OFF" position. The hand held
Diagnostic ACE must be connected and observed
during a false alarm. Once the ignition key is turned to
"OFF" position, the TurfDefender will reset itself.
5. Your Authorized Toro Distributor has equipment to
analyze system problems.
IMPORTANT: The Diagnostic ACE displays must
not be left connected to the machine. It is not de-
signed to withstand the environment of the ma-
chine's every day use. When done using Diagnostic
ACE, disconnect them from the machine and recon-
nect loopback connectors to harness connectors.
Machine will not operate without loopback connec-
tors installed on harness. Store Diagnostic ACE in
dry, secure location in shop, not on machine.
