2. Breaking in the engine (first 50
hours)
The new tractor should be operated carefully for the first
50 hours. This will have a large positive effect on the
lifetime and performance of the tractor throughout its
life. Pay particular attention to the following points:
(1) Refrain from abrupt starts and stops.
(2) Do not use a speed higher than necessary and do
not load the machine more than necessary.
(3) Begin operation only after the engine has warmed
up sufficiently.
(4) Slow down on rough roads or slopes.
(5) Check the tractor thoroughly after breaking it in for
the first 50 hours.
3. Starting and stopping engine
WARNING
 Before starting the engine, sit in the driver's seat
and make sure the levers and controls are within
the reach for safe operation. Negligence will
cause a serious injury.
 Do not start the engine in a closed room. Start the
engine outdoor where the good ventilation is
available. If you are forced to start the engine in a
confined room, make sure the ventilation is
proper. Gas oxidation can lead to death.
WARNING
 Before and after operation, never fail to check and
service the machine. Particular check will be
required at the clutch, brake pedals and controls,
and steering devices. Negligence can cause a
serious injury to the operator and/or damage to
the machine.
 Engage the parking brake during the warm-up
operation. Otherwise the tractor may abruptly start
to run.
NOTE:
In cold season, pay a special attention to the warm-up
for adequate operation of the hydraulic system.
