      Alan BlackAug 13, 2025
      If your Hunter Lifting Systems lift is not operating, the issue might be due to a blown circuit breaker or fuse in the shop power panel. Locate the shop power panel and restore power. Alternatively, there may be a hydraulic system malfunction; if the overload repeats, contact a factory service representative.

    What to do if the motor runs but the Hunter L401 Lifting Systems lift will not rise to full height?

      Jessica GonzalezAug 17, 2025
      If the motor runs but the Hunter Lifting Systems lift won't reach its full height, it could be due to a low hydraulic fluid reservoir. Lower the lift, check the hydraulic fluid level, and fill as needed. Also, check for any overhead obstructions to the vehicle; if present, lower the lift and remove the obstruction. If these steps do not resolve the issue, contact a factory service representative, as there may be a voltage supply issue or a hydraulic system malfunction.

      If the Hunter Lifting Systems lift continues to descend after the “Lower” lever is released, try operating the “Lower” lever again, as the 2-way valve might be stuck open. For any further assistance, contact a factory service representative.

      Amanda FitzpatrickAug 28, 2025
      If the Hunter Lifting Systems motor runs but the lift doesn't move, ensure that the vehicle's weight does not exceed the lift's capacity (14,000 lb for L401 or 16,000 lb for L404). Do not attempt to raise vehicles beyond these limits. For any further assistance, contact a factory service representative.

    What to do if the indicator does not change to green when pressing the “Latch Retract” button on Hunter L401 Lifting Systems?

      If the indicator doesn't turn green when you press the “Latch Retract” button on your Hunter Lifting Systems, try raising the lift higher before pressing the button again, as one or more lock latches might still be engaged on the lock ladder. Check the air supply and hoses for any issues with the air control. Also, check the air circuit and repair any leaks. For any further assistance, contact a factory service representative.
