Operation
1. Position downhole tool for carving. Press and hold the 2-Speed button and rotate the toolhead to
the desired position. Move the carriage forward until toolhead touches formation.
2. Begin carving. Push joystick fully forward then release to neutral to start alternating rotation. Adjust
thrust and rotation pressure as needed during carving.
3. Pause carving. Pull joystick away from neutral.
4. Resume carving. Push joystick fully forward then release to neutral to start alternating rotation.
5. Ream a newly carved section. After carving a few inches, press and hold the 2-Speed button and
move the joystick fully left for maximum rotation. When tool rotates freely, reduce rotation speed and
stop at desired carve position. Release 2-Speed button and resume carving.
6. Exit carve mode. Press bottom of AutoCarve switch. Carriage movement and rotation will stop.
Continue normal drilling.
Note: For quicker setup during a long bore, autocarve thrust and rotation settings are retained until the
unit is shutdown.
IMPORTANT:
• 2-speed thrust is not allowed in AutoCarve mode.
• AutoCarve mode is disabled while front wrench is closed.
• Adding or removing pipe does not affect AutoCarve position.
IMPORTANT: If full rotation seems restricted and insufficient to ream the hole, move carriage
back slightly un till full rotation is possible, then move carriage forward while rotating.
