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 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
whenever the control levers are out of the park position and
you rise from the seat.

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.
