Toro Reelmaster 6500–D Service Manual page 223

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
system. Normal maneuvering should not cause this
condition.
3. Air leak in system. Check to make sure cap is se-
curely on tank. Contact your local authorized Toro Dis-
tributor 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 Diagnos-
tic 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. Sometimes a "false leak
Reelmaster 6500–D/6700–D
detect" can occur when the TurfDefender erroneously
concludes that a hydraulic leak has occurred. The Turf-
Defender continually monitors several independent
functions to determine if an oil leak is occurring. These
functions are influenced by various external factors
such as ambient temperature, variations between
machines, and machine operating practices. Machine
operation in cool ambient temperatures (below 50
and/or short pass cross–cutting practices may trigger
potential false alarms. If "false leak detects" are sus-
pected, your Toro Distributor can adjust the calibration
between the Turfdefender and tractor Controller (ECU).
IMPORTANT: The Diagnostic ACE displays must not
be left connected to the machine. It is not designed
to withstand the environment of the machine's ev-
ery day use. When done using Diagnostic ACE, dis-
connect them from the machine and reconnect
loopback connectors to harness connectors. Ma-
chine will not operate without loopback connectors
installed on harnesss. Store Diagnostic ACE in dry,
secure location in shop, not on machine.
