Notes: • Torque figures preceded by an asterisk (*) indicate that the weaker member for the corresponding outside diameter (OD) and bore is the BOX. For all other torque values the weaker member is the PIN. • In each connection size and type group, torque values apply to all connection types in this group, when used with the same drill collar OD and bore, i.e. 2 3/8 API IF, API NC26 and 2 7/8 Slim Hole connections used with 3 1/2 X 1 1.4 drill collars all have the same minimum make-up torque of 4600 ft-lb, and the BOX is the weaker member. • Stress relief features are disregarded for make-up torque. 1
Basis of calculations for recommended make-up torque assumed the use of a thread compound containing 40-60% by weight of finely powdered metallic zinc or 60% by weight of finely powdered metallic lead, with not more than 0.3% total active sulfur (Reference the caution below.) applied thoroughly to all threads and shoulders.
Normal torque range is tabulated value plus 10%. Higher torque values may be used in extreme conditions.
Make-up torque for 2 7/8 PAC connection is based on 87 500 psi stress and other factors listed in footnote 1.
Make-up torque for H-90 connection is based on 56 200 psi stress and other factor listed in footnote 1.
CAUTION: Thread compounds made according to API Bul 5A2 will produce excess make-up and are not recommended for use on rotary shouldered connections.
This information has been duplicated in its entirety from API RP 7G Table 14 and API Spec. 7, Appendix F and is current as of the publication of this Manual. However, it is likely that the data will be updated several times during the life of a Top Drive unit. Consult API Recommended Practices or IADC Drilling Manual to be certain that this information is current.

Notes: • Torque figures preceded by an asterisk (*) indicate that the weaker member for the corresponding outside diameter (OD) and bore is the BOX. For all other torque values the weaker member is the PIN. • In each connection size and type group, torque values apply to all connection types in this group, when used with the same drill collar OD and bore, i.e. 2 3/8 API IF, API NC26 and 2 7/8 Slim Hole connections used with 3 1/2 X 1 1.4 drill collars all have the same minimum make-up torque of 4600 ft-lb, and the BOX is the weaker member. • Stress relief features are disregarded for make-up torque. 1
Basis of calculations for recommended make-up torque assumed the use of a thread compound containing 40-60% by weight of finely powdered metallic zinc or 60% by weight of finely powdered metallic lead, with not more than 0.3% total active sulfur (Reference the caution below.) applied thoroughly to all threads and shoulders. 2
Normal torque range is tabulated value plus 10%. Higher torque values may be used in extreme conditions.
Make-up torque for 2 7/8 PAC connection is based on 87 500 psi stress and other factors listed in footnote 1.
Make-up torque for H-90 connection is based on 56 200 psi stress and other factor listed in footnote 1.
CAUTION: Thread compounds made according to API Bul 5A2 will produce excess make-up and are not recommended for use on rotary shouldered connections.

Raise the BUW Gripper assembly. Lower the BUW Gripper assembly. Open the BUW Gripper to allow normal Top Drive rotation. Maintain the BUW gripper at its current height. Close the BUW Gripper on the tubular. This position is spring returned. Normally use this position to close the Gripper to avoid inadvertent hoisting with the Gripper closed. If the handler is locked and the top drive is not rotating, the BUW Gripper will hold the tubular for make-up or break out operations. The BACK-UP WRENCH CLOSED indicator will show Gripper is closed. This is a warning to avoid hoisting with the BUW Gripper closed. Same as the Normal Close position except this position is maintained. The BUW gripper will close and remain closed when this button is activated on the OIT Screen regardless of the BUW Joystick position. If the Joystick is in the Open (Neutral) position and pressure is not maintained on the button, the gripper will open.
IMPORTANT: Neither electric motor torque nor Torque Boost torque are permitted if the BUW Gripper is closed and the Handler is unlocked. In that condition the bails could swing unexpectedly causing severe damage, injury, or death.

Canrig Model 1250AC-681 Top Drive BACK-UP WRENCH SAVER •
The BUW Gripper is interlocked to the draw works clutch. This prevents damage to the wrench assembly when the Top Drive is inadvertently hoisted with the BUW Gripper closed. The Gripper will open if either draw works clutch is engaged, regardless of the joystick position.
After breaking out of a joint, remember to open the BackUp Wrench before hoisting to avoid damage to the wrench.
Be careful in using the gripper OIT screen button to hold up a sub or stabilizer for handling. If a draw works clutch is engaged, the HPU is turned off, or if the Top Drive switch (SW1) is moved to the OFF position, the Back-Up Wrench Saver will open the Gripper and drop the sub.
