LOADER TECHNIQUES
4.18.2. DIGGING, CLEARING AND LEVELING
1. When digging or excavating lower the bucket to the ground. Adjust the angle of the cutting edge
when the machine moves forward (Fig. 4.52). Change inclination of the angle of the cutting edge
and cutting depth using the boom and bucket control levers depending on bucket filling. Establish
the parameters to obtain the best bucket filling. When the bucket is full, roll it back and raise it
clear off the ground and carry the load to the desired dump area.
Fig. 4.51. Digging or Excavating
Clearing an excavation (Fig. 4.52) may be performed with the bucket partly in the dump position by
disposing of the material carried in the bucket.
It is recommended to clear an excavation a little above the ground level because after compaction
the ground will be level. Approach an excavation at the right angle and stop the front wheels at a
safe distance from the edge of the excavation.

WARNING! Never backdrag, push any objects (trees, rocks, etc) with the bucket
in the utmost dump position as due to unfavorable distribution of forces a
serious damage to loading mechanism can result. It is particularly unfavorable
when operating with boom raised.
