use sketches/diagrams to assist in training
bucket-end first
once bucket reaches corner, slowly begin the turn
as soon as front tire reaches the corner, swivel to complete turn
The wheels on a scoop do not turn, the entire machine articulates
as soon as front tire passes the corner, begin straightening out your turn in line with left rib

put tram in forward position
push material towards load point
clean middle of the entry first, then right rib (where cables usually are), then left rib, re-scoop middle once more
cleaning right rib
position scoop at 45 degree angle to the right rib
this allows the bucket to push along rib and pick up loose material
align front corner of bucket with rib to help keep the operator's compartment from ribbing
allow the bucket corner to slide along the right rib while tramming forward
push material to the load point
observe front right corner bottom of bucket and surface of area you are cleaning to be sure you are picking up loose material
If the bucket tries to ride up the right rib, stop, back off and reposition/re-angle your machine
cleaning left rib

left rib is harder to clean, usually jagged and may take more than one pass
once you back out of pass, you can see remaining material better
sometimes it is necessary to turn machine around and push material to the center of a break-through, etc. where it can be picked up
allow the bucket corner to slide along the left rib while tramming forward
push material to the load point
cleaning break-through
push material into center of the entry intersection to be picked up
