Using the Safety-Interlock
System
DANGER
If safety-interlock switches are disconnected
or damaged, the machine could operate
unexpectedly, which will result in serious
injury or death.
• 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
PTO from engaging unless you do 1 of the following:
•
Move either motion-control lever to the center,
unlocked position.
•
Press the O
position on the PTO switch.

The safety-interlock system is designed to stop
the blades/attachment if you move or release
both motion-control levers into the N

The hour meter has symbols to notify the user
when each interlock component is active. When
the component is active, a triangle lights up in the
corresponding square

in the correct position.
