OPERATION GENERAL

Filling the Bucket
Operate two or more controlled functions at the same time
throughout the filling cycle for smooth action and
maximum performance.
Control the bucket attitude throughout the digging
cycle to keep the teeth at the proper angle for best
penetration. This will minimize dragging and scraping
the bucket through the ground.
When digging in hard-packed soil, bucket penetration
can be increased by applying down pressure with the
boom while crowding in and curling the bucket. If the
crowd action “stalls” it may be necessary to apply lift
occasionally during the digging cycle to correct the
bucket depth.
To obtain a cleaner trench and avoid the buildup of
material directly in front of the backhoe, crowd out and
completely curl the bucket while starting to lift it from
the excavation. In this way excess material will fall back
into the excavation.
Dumping the Bucket
To dump the bucket at the end of the digging cycle,
lift the bucket clear of the trench while crowding it out
and swinging it to the spoil pile.
As the pile is approached, dump the bucket. When the
bucket is empty, the dipstick and bucket are in posi-
tion to resume digging upon return to the trench.
I
MPORTANT: Avoid constant jarring or hammering
type contact between the spoil pile and the loaded
bucket as this may cause premature wear to the
backhoe pins and bushings.
