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 using the tong lift handles as shown in the diagram below. Adjust the tongs as described
and latch the tong chains.
CAUTION: The vee-saddles must be used to support the tool while torquing.
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 PETOL™ 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.
