12.9.1 DIGGING OPERATIONS

WARNING
Always set the machine facing directly to the front when
carrying out digging or scooping operations. Never carry out
these operations with the machine articulated.
NOTICE
If the tires slip, the tire life will be reduced, so do not allow the
tires to slip during operation.
‡ Scoop up the piled soil by moving the machine forward as
shown below. If the tires begin slipping under heavy load, raise
the bucket slightly to reduce the load.
1. Force the bucket into the pile of soil while moving the machine
forward.
2. After the bucket has fully penetrated into the soil, place the work
equipment control lever in raise position while moving the
machine forward. Move the work equipment control lever to tilt
position from time to time until the bucket is filled with soil.
Try to keep the load in the center of the bucket; if the load is on
one side of the bucket, the load will be unbalanced.
3. When it is difficult for the bucket to penetrate into the piled soil,
move the work equipment control lever left and right to move
the bucket teeth up and down.
