and common sense levels of each operator
of t he H ol e D ig ge r. U ti li za ti o n of
non f li gh te d a n d f ul l fl ig ht e d a ug er
extensions requires the accumulation of
actual hole digging experience, skill and
common sense. Each operator must decide
if his experience, skill and common sense
level is sufficient to allow him to proceed
with the utilization of nonflighted and full
flighted auger extensions for any given
and/o r specific job application.
Follow this accepted procedure for utilizing both
nonflighted
and full flighted auger extensions to extend
the digging depth:
1) Dig to the approximate full depth of the auger,
utilizing the described operating instructions. Remove
as much loose soil from the hole as possible with the
auger rotating at a lower rotational speed.
2) STOP the engine and remove the auger from the
hole. Disconnect the spark plug wire to prevent
accidental engine starting. Close the fuel tank breather
vent (if so equipped). Turn the fuel tank ON/OFF valve
to the OFF position.
3) Disconnect and remove the Hole Digger from the
auger. Reposition the auger in the hole. Attach the
auger extension to the auger and secure with an auger
pin. The Hole Digger can now be connected to the
auger extension and secured with an auger pin.
Reconnect the spark plug wire.
4) Follow the instructions outlined for starting and
operating the Hole Digger. Use extra caution when
starting the engine with the auger in the hole. Proceed
to dig to the desired depth or to the full depth of the
auger extension. FIGURE 23.
5) Use of the nonflighted auger extension to extend the
digging depth is limited to one unit. For multiple use of
full flighted auger extension, repeat the above
procedure until the desired digging depth is achieved.

THE NONFLIGHTED AUGER EXTENSION IS
NOT EQUIPPED WITH AUGER FLIGHTING

USE OF NO NF LI GH T ED AU GE R
EXTENSIONS WILL ALLOW THE AUGER TO

CONTROL AND PERSONAL INJURY WHILE
DIGGING.
After the desired diggi n g depth has be e n
achieved, both nonflighted and full flighted
auger extensions are removed by utilizing this
accepted procedure:
1) Remove as much loose soil from the hole as
possible with the auger rotating at an intermediate
speed. STOP the engine and disconnect the spark plug
wire to prevent accidental engine starting. Close the
fuel tank breather vent (if so equipped). Turn the fuel
tank ON/OFF valve to the OFF position.
2) Lift the auger extension(s)/auger and the Hole
Digger up far enough out of the hole so that an auger
extension is clear. Block the remaining auger/auger
extension string with an auger fork to prevent it from
falling back into the hole. An additional Crew Member
will usually be required. Disconnect the Hole Digger
from the auger extension(s)/auger. Store on the job site
