To check for pipeline leaks, start by digging a bellhole about six feet

wide and ten feet long.  Then, dig lengthwise along the pipeline to locate
the leak.  Once the leak is located, position the unit to dig at grade level on
both sides of the pipeline.  If a section of pipe is to be replaced, strip the
soil from both ends of the bellhole.  Enlarge the hole enough to allow the
workmen adequate working space in the leak area.

DIGGING STRAIGHT WALL SHALLOW BASEMENTS

Begin at one corner, and remove as much material as possible to

grade level.  Reset the unit forward and continue digging to the grade level.
Progress around the edge of the basement, finishing each corner as you
come to it.
