OPERATION

STEERING THE MACHINE

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.
Do not continue to apply force to the steering wheel when it has been
turned fully to the left or right. This will make the oil temperature in the
circuit rise and will cause overheating.
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.

LOADING OPERATIONS

When using a large wheel loader to load large rocks, if the rocks are loaded directly into the dump body parts of the
dump body may be deformed. To prevent this, when loading large rocks, first load sand or soil to act as a cushion,
then load the rocks on top of this to reduce the impact on the dump body.
In addition, when loading rocks that exceed the following conditions, install the optional dump body reinforcement
plate.
Rocks with one side over 0.5 m (1 ft 8 in)
Rocks of hardness more than 4.5 (Mohs scale)
Rocks with a weight of more than 300 kg (662 lb)
When transporting steel ingots
NOTICE
When traveling, always set the dump lever to the FLOAT position regardless of whether the dump body is empty or loaded.
If the dump lever is not at the FLOAT position and the gear shift lever is not at the N position, the central warning lamp will flush
and the alarm buzzer will sound.
