Verify Interlock System Operation

CAUTION
The interlock switches are for the operator's
protection; do not disconnect them. Check the
operation of the interlock switches daily for
proper operation. Replace any malfunctioning
switches before operating the machine.
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.
1. Sit on the seat, engage parking brake and move
functional control lever to NEUTRAL. Try to depress
traction pedal. If the pedal does not depress, the inter-
lock system is operating correctly. Correct problem if not
operating properly.
