Understanding The Diagnostic Light; Changing The Counterbalance Settings; Checking The Interlock Switches - Toro 30864 Operator's Manual

Understanding the Diagnostic
Light
The machine is equipped with a diagnostic light which
indicates if the machine detects a malfunction. The diagnostic
light is located on the InfoCenter, above the display screen
(Figure 18). When the machine is functioning properly
and the key switch is moved to the On/Run position, the
diagnostic light will turn on briefly to indicate the light
is working properly. When a machine advisory message
is displayed, the light will illuminate when the message is
present. When a fault message is displayed, the light will blink
until the fault is resolved.

Changing the Counterbalance
Settings
During different times of the mowing season or when turf
conditions vary, the amount of counterbalance (upward lift)
required on the cutting decks can be changed to meet the
conditions.
1. Position the machine on a level surface, lower the
cutting decks, stop the engine, engage the parking
brake, and remove the key from the ignition switch.
2. In the InfoCenter Settings Menu, scroll down to
Counterbalance.
3. Press the right button to select counterbalance and
change between the low, medium, and high settings.
Note: Once the adjustment has been completed, move
the machine to a test area and operate the machine with
the new setting. The new counterbalanced setting may
change the effective height of cut.

Checking the Interlock
Switches
The purpose of the interlock switches is to prevent the
engine from cranking or starting unless the traction pedal is
in the Neutral position, the Enable/Disable switch is in the
Disable position, and the Lower Mow/Raise control is in the
Neutral position. In addition, the engine should stop when
the traction pedal is pressed with operator off of the seat or if
the parking brake is left engaged.
CAUTION
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
Verifying the Interlock Switch Function
1. Park the machine on a level surface, lower the cutting
units, stop the engine, and engage the parking brake.
2. Turn the key switch to the On position, but do not
start the machine.
3. Locate the appropriate switch function in the
diagnostics menu on the InfoCenter.
4. Individually, change each of the switches from open to
closed (i.e., sit on seat, engage traction pedal, etc.), and
note that the appropriate state of the switch changes.
Repeat this for all switches that you can change by
hand.
5. If a switch is closed and the appropriate indicator does
not change, 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 InfoCenter display 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. Turn the key switch to the On position and start the
machine.
3. Locate the appropriate output function in the
diagnostics menu on the InfoCenter.
4. Sit on the seat and attempt to operate the desired
function of the machine. The appropriate outputs
should change state to indicate that the ECM is turning
on that function.
