Operation
(continued)
Do not shovel dirt away
from a rotating auger, as
the shovel can be caught
and thrown by the auger.
To prevent injury, keep an
area of at least
twenty-five feet (25’)
around the auger clear of
bystanders and all other
people.
The hydraulic flow rate and pressure should not exceed the earth auger's specified
maximums. The hydraulic minimums must be met to deliver satisfactory
performance. Use only enough down pressure to assure positive penetration of
the auger into the ground. Reduce down pressure if auger rotation slows
down drastically or stalls. Excessive down pressure will cause the auger to
frequently stall. Refer to Hydraulic Requirements section for filtration, pressure,
and flow rate specifications.
If you have difficulty penetrating hard ground, refer to the Troubleshooting section.
When the auger has been lowered about 24" into the ground, raise the auger
almost out of the hole to clear the dirt, then drill deeper and raise the auger again.
Repeat this procedure until the desired hole depth is reached.
The earth auger should be raised and lowered by changing the elevation and not
the tilt of the quick attach plate.
When the auger has reached the full depth required, allow the auger to dwell
momentarily at this depth at a slower speed to assist in cleaning out the hole.
Deactivate the earth auger, and raise it from the hole.
For “heavy” soil conditions, allow the auger to turn at slow speed while raising it
to the top of the hole.
Move away from the hole, then remove loose dirt from the auger by momentarily
actuating the earth auger and spinning it at a faster speed than used for drilling. To
remove clay or other stubborn soil, actuate in a forward-stop, forward-stop manner.
Do not actuate the earth auger in a forward-reverse manner, as damage may result.
If necessary, repeat STEPS 8 - 10 to obtain a cleaner hole.
In some soil conditions, or when excessive down pressure is applied, the auger may
screw itself into the ground and become stuck, causing the earth auger to stall. Do
not attempt to pull the auger out of the ground. Instead, reverse the auger rotation
(counter-clockwise), and slowly raise the auger. Once unstuck, continue operation.
If the auger becomes lodged under rocks, roots, or other large obstructions, do not
attempt to pull the auger out of the ground. If this happens, reverse the auger
rotation (counter-clockwise), and slowly raise the auger. Once unstuck, continue
operation.
Deactivate the auger and place the drive unit in the cradle when moving between holes.
Frequently check the condition of the auger teeth and point, and replace them
when wear is detected. Always keep spare parts on hand for replacements to avoid
damage to the auger head and auger flighting.
