GENERAL OPERATIONGENERAL OPERATION
Side Slope Excavating or Trenching
Dig with backhoe uphill whenever possible.
Level the backhoe on slops with the stabilizers to
dig plumb trenches, or use the backhoe orloader
to cut a level slot for the uphill wheel and stabilizer.
Pile the spoil from the slot on the low side.
When on the side of a steep slope, cut a level
surface along the uphill side of the trench with the
loader. Pile the spoil of the cut downhill. When
digging, pile the spoil of the trench uphill.
Dig eld trenched progressively. As soon as one
trench is completed, have the workmen lay the
tile. Start the next trench, using the spoil to ll the
previous trench.
Finishing Straight Walls
When nishing straight walls or bell holes in
sandy soil, use a platform under the rear tires and
stabilizers. The platform distributes the load over
a larger area and lessons the possibility of a cave-
in. The platform also tends to keep the unit from
creeping rearward if hard digging is encountered.
Finish the far wall by crowding out while forcing
the bucket down from the boom. Actuate the
bucket(curl out) to keep the bottom of the bucket
vertical. To nish the near wall, lift up and crowd in.
Keep the edges of the bucket horizontal.
Backll by lifting the bucket over the spoil pile and
then crowding in. Pull both the crowd and lift levers
for smooth, even backlling.
IMPORTANT: Do not backll by using the swing
circuit and dragging the bucket sideways. Doing so
can cause damage to the dipper stick boom swing
cylinders or mainframe.
