STEERING THE MACHINE
WARNING
If the machine is turned at high speed or on a steep slope, there is danger
that it will turn over, so do not operate the steering in such conditions.
CAUTION
Do not continue to turn the steering wheel when it has been turned fully
to the left or right. Continuing to turn the steering wheel will make the
oil temperature in the circuit rise and cause overheating.
When the steering nears the end of the turn on the left or right, turn the
steering wheel more slowly. Turning the steering wheel suddenly to the
end of the turn will cause damage to the machine.
To turn the machine when traveling, turn steering wheel (1) in the direction of the turn.
When traveling around a curve, release the accelerator pedal before entering the curve, shift down to a lower speed
range, then depress the accelerator pedal to travel around the curve. Never coast around the curves at high speed.
REMARK
The angle of the steering wheel may change (the position of the spoke may change slightly) when the machine
is traveling, but this is not a failure.
If force is applied to the steering wheel when the tires have been turned fully to the left or right, the steering wheel
will turn a little at a time, but this is not a failure.
OPERATION USING DIFFERENTIAL LOCK
When traveling on the roads where the tires are likely to slip, avoid sudden changes in speed, and use the differential
locks (inter-axle differential lock, left and right differential lock) when traveling.
Operate the inter-axle differential lock switch and left and right differential lock pedal to actuate the differential lock
5 to 10 m (16 ft 5 in to 32 ft 10 in) before entering a road surface where the tires are likely to slip.
It is important to actuate the differential lock before the tires slip in order to obtain the full ability of the differential lock
and also to reduce wear of the tires.
NOTICE
As far as possible, do not use the differential lock (inter-axle, left and right differential lock) when turning.
If the differential lock is used when turning:
It will be difficult to operate the steering wheel.
It will become more difficult to turn than when the differential lock is not used, and in some cases, it may not be possible to steer
around curves which were previously possible.
When the left and right differential lock is actuated, the wheel on the inside of the curve attempts to turn at the same speed as
the wheel on the outside, so the wheel may spin and there may be premature wear of the tire or damage to the road surface.
When traveling on dry roads or other road surfaces where the friction index is high, if the left and right differential lock is
actuated, the differential lock will slip in order to absorb the difference in rotating speed between the left and right wheels
caused by turning, and this will reduce the durability of the differential lock. Noise will also be generated when the differential
lock slips.
When the left and right differential lock is actuated, the load on the final drive increases, and this may reduce the service life
of the final drive.
