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 NEUTRAL, the
Enable/Disable switch is in DISABLE and the Lower Mow/Raise
control is in the neutral position. In addition, the engine will stop
when the traction pedal is depressed with the operator off the seat.
To verify interlock switch function:
THE INTERLOCK SWITCHES ARE FOR THE
PROTECTION OF THE OPERATOR AND
BYSTANDERS, AND TO ENSURE CORRECT
OPERATION OF THE MACHINE, SO DO NOT
BYPASS OR DISCONNECT THEM. CHECK
THEIR OPERATION DAILY TO INSURE THEY
ARE OPERATING CORRECTLY. IF A SWITCH
IS DEFECTIVE, REPLACE IT BEFORE OPERAT-
ING THE MACHINE. HOWEVER, DO NOT
RELY ENTIRELY ON SAFETY SWITCHES,
ALSO USE COMMON SENSE!
1.
Park the machine on a level surface, lower the cutting units,
stop the engine and engage the parking brake.
2.
Open the control panel cover. Locate the wire harness and con-
nector. Carefully unplug the loopback connector from the har-
ness connector.
3.
Connect the Diagnostic ACE display connector to the harness
connector. Make sure the correct overlay decal is positioned on
Diagnostic ACE display.
4.
Turn the key switch to the ON position, but do not start the
machine.
Note: The red text on the overlay decal refers to input switches
and the green text refers to outputs.
5.
The "inputs displayed" LED, on lower right column of the
Diagnostic ACE, should be illuminated. If the "outputs dis-
played" LED is illuminated, press and release the toggle button
on the Diagnostic ACE to change the LED to "inputs dis-
played". Do not hold the button down.
