1.
Select a safe ground travel speed when transporting
from one area to another.
2.
Transport Post Hole Digger low to the ground to
maintain stability but at a height that does not block
your view:
•
Skid/Loader Plate Mount:
Transport with
cylinders on end of loader arms fully retracted,
motor/gearbox housing supported in the rest
support, and auger low to the ground at a height
that does not block your view.
•
Bucket Mount:
Transport with auger hanging
straight down and low to the ground at a height that
does not block your view.
3.
Always travel straight up and straight down inclines.
Make turns only on level ground.
4.
Enter ditches and inclines slowly to make sure the
auger does not dig into the ground. Stop and raise
auger if needed to cross a ditch or start up an incline.
5.
Reduce skid steer ground speed when turning.
Leave enough room to clear obstacles such as
buildings, trees, and fences.
6.
Keep away from electrical power lines. Place an
orange warning sign under overhead power lines
indicating type of danger above.
7.
When traveling on roadways, transport in such a way
that faster moving vehicles may pass you safely.
8.
Reduce transport speed when traveling over rough
or hilly terrain.
Operating Instructions
1.
Carry the auger low to the ground while traveling
between drilling positions.
2.
Position tractor on the upside of the hill when drilling
a hole. This will greatly improve its balance and down
force.
3.
Experiment with auger speeds before digging.
Increase engine speed to increase auger speed and
decrease engine speed to reduce auger speed. Run
at higher speeds when digging in soft and/or sandy
soils and lower speeds when digging in hard, rocky
or frozen soils. Normal auger speed is 85 to 100 rpm.
Never exceed an auger speed of 110 rpm or the
equipment can become damaged.
4.
Maker sure auger rotation is stopped and then lower
auger point to the ground.
5.
With engine running at a slow speed, start auger
turning clockwise. Increase engine speed to desired
digging speed.
6.
Periodically adjust the machine’s position to keep the
auger and hole vertical. Be careful not to damage
gearbox or auger.
7.
If possible, apply down pressure to assist penetration
into the ground. If auger speed slows or stops, back
off down pressure. Excessive down pressure can
stall the auger.
IMPORTANT:
Operate one function at a time.
IMPORTANT:
pressure on the auger while in the ground. This can
damage the auger and drive components.
IMPORTANT:
Always stop auger from rotating
before raising it out of the hole. This will keep auger
from wobbling with an unbalanced dirt load.
IMPORTANT:
If auger stalls while digging, raise
auger to free it. Continue normal digging operations
by lowering the auger slowly into the hole.
IMPORTANT:
If auger starts to screw itself into the
