Verify Interlock System Operation

The interlock switches are for the operator's
protection; do not disconnect them. Check the
operation of the switches daily to assure the in-
terlock system is operating. If a switch is defec-
tive, replace it before operating the machine. Re-
gardless if switches are operating properly or
not, replace them every two years to assure max-
imum safety.
The purposes of the interlock switches are to:
A. Prevent the engine from cranking or starting un-
less the Functional Control Lever is in NEUTRAL.
B. Prevent operating the traction pedal with the
Functional Control Lever in NEUTRAL.
C. Shut off the engine if the operator leaves the seat
without the Functional Control Lever in NEUTRAL.
D. Shut off the reels if the Functional Control Lever
is moved to NEUTRAL or TRANSPORT.
