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 prevents the PTO from
engaging unless you do the following:
•
Move either motion-control lever down to the
center, unlocked position.
•
Press the O
N
position on the PTO switch.
The safety-interlock system also disengages the PTO
if you move or release both motion-control levers into
the P
ARK
position.
Symbols display on the InfoCenter to notify the user
when each interlock component is in the correct
position.
