Understanding the Safety-Interlock
System
WARNING
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.
The safety-interlock system is designed for the following:
•
To prevent the engine from starting unless the traction
pedal is in the neutral position.
•
To automatically ensure that the parking brake is engaged
and the PTO is off when starting.
•
To stop the engine whenever the traction pedal is not in
the neutral position and you rise from the seat.
•
To automatically engage the parking brake and disengage
the PTO, when you rise out of the seat with the traction
pedal in the neutral position.
•
To stop the engine whenever the parking brake is not
engaged and you rise from the seat.
