Important: Ensure that the fuel-shutoff valve is closed
before transporting or storing the machine, as fuel
leakage may occur. Set the parking brake before
transporting. Make sure to remove the key as the fuel
pump may run and cause the battery to lose charge.
Using the Safety-Interlock
System
CAUTION
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 following occurs:
•
The parking brake is engaged.
•
The blade-control switch (PTO) is disengaged.
•
The motion-control levers are in the N
position.
The safety-interlock system also is designed to shut off
the engine when you move the traction controls from the
L
position with the parking brake engaged or if you

rise from the seat when the PTO is engaged.
The hour meter has symbols to notify the user when the
interlock component is in the correct position. When the
component is in the correct position, a triangle lights up in
the corresponding square.
