68 OPERATING THE BACKHOE

GENERAL BACKHOE OPERATION

To avoid personal injury:
A Do not dig under the stabilizer or tractor,
especially in soft or sandy condition.
Take extra precaution in wet or thawing ground.
These conditions can become unstable very
quickly and may collapse under the weight of the
machine and may tip over.
A Use care for buried material such as electrical,
telephone, gas and water lines. When in doubt,
contact local utility companies for their buried
location.
A Do not use the tractor to pull out tree stumps with the
boom dipper extended and the bucket in its crowded
position.
BDipperstick Digging
Lower the bucket to the ground, the same as with bucket
digging, then curl until the bucket teeth are flat on the
ground.
Using only the crowd cylinder, retract the dipperstick,
dragging the bucket through the trench until it is
approximately half full. Begin to curl the bucket in while
continuing to crowd in, until the bucket is completely full.
Raise and swing the boom and dump the bucket in the
spoil area on the high side of the trench or excavation.
BSpoil Pile Location
To avoid personal injury:
A Do not place spoil close to the edge of the
excavation where its weight could cause a cave-in.
Carefully preplan the location for the spoil that will be
removed from the excavation. The location will vary
depending on the excavation being dug.
The height of spoil pile can be controlled without moving
the tractor. Approach the pile with the backhoe bucket full
and ready to empty. Instead of dumping on top, lower the
full bucket into the top of the pile. Begin dumping and
crowding out at the same time. As the bucket opens and
dumps, the bottom of the bucket will push the top of the
pile off and behind its location, safely away from the
excavation.
BStraight Wall or Cemetery Digging
Strip the top soil off the ground, within the confines of the
straight hole or grave to be dug. Clean out as much
material, within the same confines, as possible with
normal digging methods.
Finish the far wall by crowding out while forcing the bucket
down with the boom.
Curl the bucket out to keep the bottom of the bucket
vertical while making the down cut.
