Loading
To load the downhole tool in the unit, adjust the vee-saddles to support the tool. Set the tool
into the unit. Position the tongs for make up or break out as needed and set the tongs onto
the tool. Adjust the tongs as described and latch the tong chains.
CAUTION: The vee-saddles must be used to support the tool while torquing.
Tong Adjustment
Add or remove chain sections as needed using the splice bolts in the chains. Push on the top
of the jaw to fully compress the spring inside the jaw. Adjust the chain screw nut so that
the chain is as tight as possible and fit into the lugs in the jaw.
Warning:
Flat side of chain screw must not make contact with the workpiece.
Contact could result in failure. Contact is due to improper chain
selection. See selection guide for proper chain and description.
Breaking Out
Load the tool and adjust the tongs as described above. Fully ratchet the tong by extending
the cylinder. Set the system pressure to a minimum. Retract the cylinder. When the tong
stops, begin increasing the system pressure. Keep increasing the system pressure until the
connection is broken loose or the working load of the tong is reached. Do not exceed the
rating of the tong. Consult with GEARENCH as needed for help with the toughest
break out jobs. After the initial break out, ratchet the tong fully and then alternately extend
and retract the cylinder until the connection is fully loosened.
Making Up
Load the tool and adjust the tong and vise as described above. Make up the connection hand
tight using TITAN chain tongs. Preset the system pressure to obtain the desired torque if
possible. Retract the cylinder. If the cylinder fully retracts without stalling, cycle the tong
(extend / retract). Continue until the cylinder stalls or until the desired pressure is obtained.
Warning: Do not stand in line with the tongs or chains during operation.
