addition, the engine should stop when you press
the traction pedal while you are off the seat or if the
parking brake is engaged.
CAUTION
If the safety-interlock switches are
disconnected or damaged, the machine could
operate unexpectedly, causing personal
injury.
• Do not tamper with the interlock switches.

Service Interval: Before each use or daily
1. Park the machine on a level surface, lower the
cutting units, shut off the engine, engage the
parking brake, and remove the key from the
ignition switch.
2. Turn the key in the ignition switch to the O
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.
Note:
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.
Note:
Replace any faulty switches and repair
any faulty 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 the Output Function
1. Park the machine on a level surface, lower the
cutting units, shut off the engine, engage the
parking brake, and remove the key from the
ignition switch.
2. Turn the key in the ignition switch to the O
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.
Note:
The appropriate outputs should change state
to indicate that the ECM is turning on that function.
If the correct outputs do not illuminate, verify that the
required input switches are in the necessary positions
to allow that function to occur. Verify the correct switch
function.
If the output displays are on as specified, but the
machine does not function properly, this indicates
a non-electrical problem. Repair the machine as
necessary.
