Add Rod

1.

Stop drilling attachment.

2.

Back up tractor 6" (150 mm) to loosen drill rod in ground.

3.

Disconnect drill rod from drilling attachment.

4.

Move tractor away from bore.

5.

Add one drill rod to continue bore.

Backream

After drill bit enters target trench, the bore hole may be enlarged by changing the drill bit to a backreamer
and drawing it back through the initial bore.

1.

Turn tractor ignition switch to STOP.

2.

Replace drill bit with backreamer.

3.

Start tractor engine and begin clockwise rotation.

4.

Slowly back up tractor while maintaining rotation.

5.

When backreamer exits the bore hole, stop rotation immediately.

IMPORTANT: Always rotate clockwise during backreaming. Rotate counterclockwise only to
dislodge a dry bore bit or reamer that has siezed in the bore hole.

IMPORTANT:

Do not try to increase hole size too much in one pass. Several passes using successively
larger reamers will save wear on machine.

During backreaming, keep drill string straight. Sharp bends in the drill rod at the motor
coupling can cause rod failure.
