Operation
14. Use standard pipe handling procedures to remove and rack the freed tubing stand.
15. Repeat steps 5 through 14 as many times as necessary to break out and un-thread the desired number of
connections.
10. Stop rotation when the connection breaks, and shift to high gear. This will enable the tong to completely
un-thread the connection at high speed.
11. Release the tong jaws from the tubing by reversing rotational direction when connection has been completely
unthreaded.
12. When the tong jaws disengage, align the opening in the rotary gear with the mouth of the tong, and open the
tong door.
13. Free the tool from the drill string. Note that rig personnel may be required to stabilize the tool as it completely
releases from the drill string. Guide the tool away from the string and use the lift cylinder control to lower it to
the drill floor if desired.
!
CAUTION
RIG PERSONNEL MUST STABILIZE THE TOOL AS IT IS FREED FROM THE TUBULAR.
!
WARNING
DO NOT APPLY BREAK-OUT TORQUE IF THE ROTARY GEAR IS NOT IN FULL CONTACT WITH BOTH
IDLER GEAR ASSEMBLIES.
