The Safety Interlock System
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.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
•
You are sitting on the seat or the parking brake
is engaged.
•
The power take off (PTO) is disengaged.
•
The traction pedal is in the neutral position
•
The engine temperature is below the maximum
operating temperature.
The safety interlock system also is designed to stop
the engine when the traction pedal is moved from the
neutral position with the parking brake engaged. If
you rise from the seat when the PTO is engaged there
is a 1 second delay and then the engine stops.
