b. Digging With Bucket:
This is the procedure recom-
mended when a vertical wall is
desired at the end of a trench.
i. Set the bucket so the bucket
teeth are nearly vertical.
ii. Use the boom to force the
bucket into the ground.
iii. Use the boom to force
the bucket further into the
ground and at the same time
roll the bucket back (curl)
until it is full.
iv. Raise the boom and dump
the bucket.
v. Continue to dig in the same
way by digging 3 to 6 inches
(75 to 150 mm) deeper each
time.
c. Positioning:
i. Position the unit so the
boom is centered behind the
frame.
