Once the sides are cleaned up, finish grading the bottom of the exca-
vation. This is done by making the remaining cuts long and shallow, con-
centrating on making them level and smooth. Remove any remaining spoil.
Check the excavation bottom for depth and levelness, making any adjusting
cuts as needed.
The basic steps just listed at the same regardless of the excavation.
All other digging jobs are simply variations of this basic procedure. Remem-
ber to make your cuts in smooth cycles. This will reduce operator fatigue
and machine wear while increasing productivity and efficiency.
SPECIAL APPLICATIONS
TRENCHING BETWEEN A BUILDING AND AN OPEN EXCAVATION
Start the trench at the building and trench toward the open excava-
tion. Dig toward the open excavation until there is just enough room to
move the unit out from between the trench and open excavation.
