Operating Characteristics - Toro 03708 Operator's Manual

7. The "inputs displayed" LED, on the lower
right column of the Diagnostic ACE, should be
illuminated. If the "outputs displayed" LED is
illuminated, press the toggle button, on Diagnostic
ACE, to change LED to "inputs displayed".
The Diagnostic ACE will illuminate the LED
associated with each of the inputs when that input
switch is closed.
8. Individually, change each of the switches from
open to closed (i.e., sit on seat, engage traction
pedal, etc.), and note that the appropriate LED
on Diagnostic ACE will blink on and off when
corresponding switch is closed. Repeat this for all
switches that you can change by hand.
9. If a switch is closed and the appropriate LED does
not turn on, check all wiring and connections to
the switch and/or check the switches with an ohm
meter. Replace any defective switches and repair
any defective wiring.
Note: The Diagnostic ACE also has the ability to
detect which output solenoids or relays are turned
on. This is a quick way to determine if a machine
malfunction is electrical or hydraulic.
Verifying Output Function
1. Park the machine on a level surface, lower the
cutting units, stop the engine, and engage the
parking brake.
2. Remove the access panel located beneath the front
of the seat.
3. Locate wire harness and connectors near controller.
4. Carefully unplug loopback connector from harness
connector.
5. Connect the Diagnostic ACE connector to the
harness connector.
Note: Make sure correct overlay decal is positioned
on Diagnostic ACE.
6. Turn the key switch to the ON position, but do not
start machine.
Note: The red text on the overlay decal refers to
input switches and the green text refers to outputs.
7. The "outputs displayed" LED, on lower right
column of Diagnostic ACE, should be illuminated.
If the "inputs displayed" LED is illuminated, press
the toggle button, on the Diagnostic ACE, to
change the LED to "outputs displayed".
Note: It may be necessary to toggle between
"inputs displayed" and "outputs displayed" several
times to do the following step. To toggle back and
forth, press the toggle button once. This may be
done as often as required. Do not hold the button.
8. Sit on the seat and attempt to operate the desired
function of the machine. The appropriate output
LEDs should illuminate to indicate that the ECM is
turning on that function.
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 Characteristics

Practice driving the machine because it has a hydrostatic
transmission and its characteristics are different than
many turf maintenance machines. Some points to
consider when operating the traction unit and cutting
units are the transmission, engine speed, load on the
cutting blades and the importance of the brakes.
To maintain enough power for the traction unit while
operating, regulate the traction pedal to keep the engine
RPM high and somewhat constant. A good rule to
follow is to decrease the ground speed as the load on
the cutting units increases, and increase the ground
speed as the load decreases.
Therefore, allow the traction pedal to move backward
as the engine RPM decreases, and depress the pedal
slowly as the RPM increases. By comparison, when
driving from one work area to another, with no load
and cutting unit raised, have the throttle in the Fast
position and depress the traction pedal slowly but fully
to attain maximum ground speed.
Another characteristic to consider is the operation
of the pedals that are connected to the brakes. The
