Breaking Out
Load the tool and adjust the tong and vise as described above. Fully ratchet the tong. Turn
the pressure control knob fully counter-clockwise, engaging the tong. When the tong stops,
begin increasing the system pressure by turning the pressure control slowly clockwise. 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 engage / ratchet the tong 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. While pressing the TONG RATCHET button with the
cylinder fully extended, adjust the pressure control knob until the desired make up torque is
displayed. Engage the tong. If the cylinder fully retracts without stalling, cycle the tong
(ratchet / engage). Continue until the cylinder stalls.
Calibration
Periodic calibration of the digital display and recorder outputs is recommended to maintain
the highest possible accuracy. The following procedures should be used for calibration.
1. Connect a calibrated pressure indicator to any pressurized port on the console.
2. Remove the digital panel meter covers as shown. The power, signal and analog output
wires must remain connected to the meter. See the calibration adjustment diagram below
for the adjustment locations.
3. Apply pressure to the pressure indicator. The table below lists the recommended
pressure values and the theoretical display and analog output values.
4. Adjust the zero and span controls as needed. Adjust the meter display prior to the analog
output, as the meter controls will also affect the analog output.
5. Replace the digital panel meter covers and return the unit to service.
