Excavation - Hitachi ZW 120-6 Operator's Manual

Excavation

Loading Accumulated Soil
IMPORTANT: Avoid operating the machine with the
front wheels raised off the ground. Machine traction
force is reduced and excessive loads are applied to the
undercarriage.
Scoop load while driving the machine forward as described
below. As load increases the wheels begin to slip, slightly
raise the bucket to reduce the load.
1. Level the bucket with the surface of the ground.
Penetrate the bucket into the accumulated soil while
driving the machine forward.
2. After the bucket has sufficiently penetrated the soil, raise
the lift arm while driving the machine forward further
and occasionally tilt the bucket back to fill the bucket.
Sometimes set the bucket in the tilt position to fill up
material in the bucket.
3. If it is difficult to penetrate the soil with the bucket, move
the bucket back and forth and the bucket teeth up and
down.
4. Drive the machine with the bucket tilted backward fully
and held at the lowest possible position.
