Note:
If the correct output LEDs do not illuminate,
verify that the required input switches are in the
necessary positions to allow that function to occur.
Verify correct switch function.
If the output LEDs are on as specified, but the
machine does not function properly, this indicates a
non-electrical problem. Repair as necessary.
Note:
If each output switch is in the correct position
and functioning correctly, but the output LEDs are not
correctly illuminated, this indicates an ECM problem.
If this occurs, contact your Toro Distributor for
assistance.
Important:
The Diagnostic ACE display must
not be left connected to the machine. It is not
designed to withstand the environment of the
machine’s every day use. When done using the
Diagnostic ACE, disconnect it from the machine
and connect loop-back connector to harness
connector. The machine will not operate without
loopback connector installed on the harness. Store
the Diagnostic ACE in dry, secure location in the
shop, not on the machine.

Operating Tips
Familiarization
Before mowing grass, practice operating the machine
in an open area. Start and stop the engine. Operate in
forward and reverse. Lower and raise the cutting units
and engage and disengage the reels. When you feel
familiar with the machine, practice operating up and
down slopes at different speeds.
Warning System
If a warning light comes on during operation, stop the
machine immediately and correct the problem before
continuing operation. Serious damage could occur if
you operate the machine with a malfunction.
Mowing
Start the engine and move the throttle to the Fast
position. Move the Enable/Disable switch to the
Enable position and use the Lower Mow/Raise lever
to control the cutting units (the front cutting units are
timed to lower before the rear cutting units). To move
forward and cut grass, press the traction pedal forward.
Note:
Allow the engine to idle for 5 minutes before
shutting it off after a full load operation. Failure to do
so may lead to turbo-charger trouble.
Transport
Move the Enable/Disable switch to the Disable
position and raise the cutting units to the transport
position. Move the Mow/Transport lever to the
transport position. Be careful when driving between
objects so you do not accidentally damage the machine
or cutting units. Use extra care when operating the
machine on slopes. Drive slowly and avoid sharp turns
on slopes to prevent roll overs. Lower the cutting units
when going downhill for steering control.
