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.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
• The blades are disengaged.
• The motion control levers are in the park position.
The safety interlock system also is designed to stop
the engine when the control levers are out of the park
position and you rise from the seat when the blades
are engaged.
Testing the Safety Interlock System
Test the safety interlock system before you use the
machine each time. If the safety system does not
operate as described below, have an Authorized Service
Dealer repair the safety system immediately.

park position, and move the blade control switch
