Cutting face operations
Do not excavate cutting faces. If the cutting face is excavated,
excessive force will be applied to the machine, and there is dan-
ger that this may damage the bucket, work equipment, or frame.
In particular, do not excavate with the bucket raised to a height
above the travel posture. For excavation of cutting faces, use a
hydraulic excavator.
Switching between forward and reverse
Do not switch the direction of travel of the machine between for-
ward and reverse when traveling at high speed or when the
accelerator pedal is depressed. When the machine is traveling
at high speed or when the accelerator pedal is depressed, the
engine speed is high, and if the direction of travel is switched
between forward and reverse. In this condition, an excessive
load will be applied to the engine, torque converter, transmis-
sion, and other parts of the power train, and this will reduce the
service life of the machine.
When switching between forward and reverse, travel at low
speed, reduce the engine speed, then stop the machine and
switch the direction of travel.
Turning when tires are stationary
Do not operate the steering when the machine is stationary. If
the steering is operated when the machine is stationary, it will
cause wear or cuts in the tires. In addition, it will reduce the
durability of the frame and the undercarriage.
