    What to do if Farr Power Tool torque gauge is indicating incorrectly?
    • K
      Kevin ParrishAug 5, 2025
      If the torque gauge on your Farr Power Tool is indicating incorrectly, the issue might stem from several causes: * The incorrect gauge may be in use. Ensure the gauge is the proper range and has been properly calibrated for the arm length of the equipment in use. * The gauge may be damaged. Check its operation and calibration on an independent system. * The gauge may have mistakenly been paired with an incorrect load cell. In addition, consider that air trapped in the torque measuring circuit (load cell, hydraulic line, or gauge) could also cause incorrect readings.

    How to troubleshoot low torque in Farr Power Tool due to fluid viscosity?
    • S
      Selena OwensAug 9, 2025
      If your Farr Power Tool isn't developing sufficient torque, the hydraulic fluid's viscosity might be the problem. Make sure the hydraulic fluid you're using matches what's recommended. If the fluid is too thick, the power unit pump might not prime correctly. If it's too thin, the hydraulic system could overheat. Replace the fluid with the correct viscosity. Also, environmental conditions can affect fluid viscosity, so ensure the fluid is suitable for the operating temperatures.

    Why Farr Power Tool tong is not developing sufficient torque due to load cell issues?
    • A
      Annette JacobsAug 18, 2025
      If your Farr Power Tool tong isn't developing sufficient torque, and you suspect the load cell is the issue, consider these possibilities: * The incorrect load cell may be in use. * The load cell may be damaged. If damaged, replace the load cell or return it for repair and re-calibration.

    Why Farr Power Tool tong will not develop sufficient torque?
    • J
      Joseph HigginsOct 31, 2025
      Several factors can prevent the Farr Power Tool tong from developing sufficient torque. It could be due to: * A malfunctioning relief valve on the tong hydraulic circuit. * A leaking directional valve, which should return fluid directly to the reservoir in the neutral position. Replace or repair the valve to ensure correct operation. * The power unit not producing adequate pressure. Troubleshoot the power unit. * Poor hydraulic pressure at the tong despite adequate pressure at the power unit, or excessive back pressure in the return line, indicating restrictions in the line between the power unit and the tong. Inspect the integrity of self-sealing couplings and check for other restrictions like contaminated catch screens or filters. * Inappropriate fluid viscosity (too high or t...
