4.3 - Auger Drilling cont.

When using screw together augers consider the following:

• When coupling augers, idle the machine down while screwing together the augers and remove the auger

catcher before rotating the auger string.

• When uncoupling augers, clean off the area where the pipe wrench jaws will engage the bottom auger.

• Drillers should remove their hands from the rotation lever or clutch handle while allowing the helper to

place the wrench in the proper position. The helper should loosely hold on to a rope attached to the end of

the pipe wrench to maintain tension. After breaking the auger, drillers should remove their hand from the

rotation lever or clutch handle while allowing the helper to remove the wrench and put the auger catcher in

place.

When using bolt-together augers, consider the following:

• Do not use bolts with excessively rounded heads or worn out threads.

• Do not use a worn out socket or breaker bar.

• Pull on the breaker bar to tighten bolts. Do not push.

• Drillers should remove their hands from the rotation lever or clutch handle while auger bolts are removed

and the auger catcher is positioned.

• If the top auger will not disengage from the string, strike the auger with a hammer on the thick area of the

female coupling end.

• Do not strike the flights, bolt holes, or the body (tube) of the auger.

• If the auger cap bolt will not loosen by hand, tap it with a hammer or use the breaker bar and socket.

• If the top cap will not disengage from the auger, strike the cap with a hammer.

When using solid stem flight augers, consider the following:

• Place the C-pin so the movement of cuttings up the flights will not disengage it.

• Drillers should remove their hands from the rotation lever or clutch handle while allowing the helper to

remove the C-pin and put the auger catcher in place.

• When hoisting a string of augers from the borehole, use the proper top adapter that will not allow the string

to become disengaged from the hoist line.
