2. Break-in (initial 50 hours)

The new tractor should be carefully operated for the first 50
hours. It will surely have an effect on the lifetime and
performance of the tractor throughout the life. Pay attention
to the following points in particular:
(1) Avoid quick start or abrupt brake if it is not in
emergency case.
(2) Do not operate in higher speed or heavier load more
than necessary. Do not operate with full load.
Avoid from operation such engine speed comes down
by a load or smoke while working.
(3) Start operation after the engine is sufficiently warmed
up.
(4) Slow down on the rough road or slope.
(5) Check tire fixing bolts at the first 10 hours and 50
hours operation. If loosened, tighten it.
See "12. Wheel tread" for bolt tightening torque.
(6) Check the tractor at the time of first 50 hours
operation.

make sure shift levers (reverser, PTO shift, range shift,
main shift) are at neutral position, and position control

the tractor. Particular check will be required at brake
pedals, controls, steering devices and tire rim fitting bolts.
Negligence can cause a heavy injury or accident to the
tractor and the human.
2) Set the parking brake during the warm-up operation.
Otherwise the tractor may abruptly start to run.
