Drilling
During normal drilling operation, the thrust/rotation joystick controls both
operations and allows any combination of the two based on the position of the
joystick:
• Push joystick toward 1A for forward thrust with clockwise rotation.
• Push joystick toward 2A for forward thrust with counterclockwise rotation.
• Pull joystick toward 2B for reverse thrust, with counterclockwise rotation.
• Pull joystick toward 1B reverse thrust, with clockwise rotation.
Assisted Makeup
During pipe change operations when front wrench is closed and carriage is on
front or rear home, the thrust/rotation joystick only controls the speed and
direction of rotation. The machine controller manages thrust and matches the
speed and direction of rotation to smoothly thread or unthread pipe sections.
Push joystick toward 1A or 1B for clockwise rotation (machine controlled
forward thrust).
Push joystick toward 2A or 2B for counterclockwise rotation (machine controlled reverse thrust).
If the thrust/rotation joystick is moved straight forward or backward so there is no rotation, only thrust is
controlled.
NOTICE: Counterclockwise rotation can unthread pipe in the ground.
