Drill bits vary in size and type to meet the various soil
conditions you may need to drill through. Some of the
possibilities are as follows:
•
Straight blade
—Used in a wide range of medium
density soils.
•
Bent blade
—Used in medium to soft soils. This
bit has an added 20° bend to increase steering
performance in soft soils.
•
Triangle point blade
—Use in hard and rocky
soils. This bit has carbide edges to reduce wear.
All of the above bits come in varying widths. A
wider blade increases your ability to steer in soft
soils. A narrower blade moves through hard soils
better. Contact your Authorized Service Dealer for a
complete list of available blades.
The sondes and receivers are essential to track
the position of the drill head throughout the drilling
operation. The sonde housing on the drill head opens
up to accept the sonde beacon which works with the
receiver to track the location, pitch, direction, head
orientation, and more of the drill head. Refer to the
Tracking System Operator’s Manual
for instructions
on using the system.
To install the sonde beacon into the sonde housing on
the drill head, complete the following:
1.
Replace the batteries in the sonde beacon as
described in the
Tracking System Operator’s
Manual
.
2.
Loosen the screws securing the housing cover
to the housing and remove the cover (
).
