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.
