OPERATION GUIDELINES
DIGGING POLE HOLES
Before digging locate all overhead lines and all underground utilities. Call 811 if available in your area, or
your state or province “Call before you dig” number. More information is available at www.call811.com
. All
underground utilities such as power lines, oil and gas lines, communication lines, waterlines, sewer lines
must be marked before digging. Failure to do so may result in action by your state or province.
Position the vehicle so the desired hole location is not at the fully retracted or fully extended position of the
second boom. To maintain a vertical hole the extension will change as the boom is lowered during digging.
After the auger has been unstored, position the auger point on stake location by using the second section
extension and rotation movement of the boom to set the point of the auger firmly on the ground. The digger
moves in and out with the hydraulic extension when it is in the lowered position and has been latched to the
second section.
When starting to dig on inclines, angle the digger/auger to the point where the auger head is perpendicular
to the incline. Turn the auger several revolutions before starting a gradual return of the digger to a vertical
position.
DIGGING HOLES ON AN INCLINE
If the vehicle is operated on sloping ground, use extreme caution when rotating toward the low side. The
load chart on the unit gives the capacity when properly stabilized on level ground. The capacity is reduced if
vehicle is not level.
An alternate method of digging on an incline is to level the digging area with a shovel before setting the
auger.
DIGGING HOLES ON AN INCLINE (ALTERNATE METHOD)
NOTE: Under normal conditions, the point of the auger is the pilot to properly locate the hole.
Remember to “Call before you dig” or 811 if available in your area or the number
for your location.
