RANSPORT
The safety-interlock system prevents the reels from operating
unless the functional-control lever is in the M
Perform the following system checks daily to ensure that the
interlock system is operating correctly:
1. Sit on the seat, move the traction pedal to the N
position, move the functional-control lever to the
N
position, and engage the parking brake.

2. Try to press the traction pedal.
The pedal should not press, which means that the
interlock system is operating correctly. Correct the
problem if it is not operating properly.
3. Sit on the seat, move the traction pedal to the N
position, move the functional-control lever to the
N
position, and engage the parking brake.

RANSPORT
The engine should not turn-over or start, which means
that the interlock system is operating correctly. Correct
the problem if it is not operating properly.
5. Sit on the seat, move the traction pedal to the N
position, move the functional-control lever to the
N
position, and engage the parking brake.

Checking the Leak Detector
The leak detector system is designed to assist in early
detection of hydraulic-fluid-system leaks. If the oil level in the
main hydraulic reservoir, is lowered by 118 to 177 ml (4 to 6
oz), the float switch in the tank will close. After a 1 second
delay, the alarm will sound, alerting the operator

operation, will cause the oil to transfer into the auxiliary oil
