  First, check that the power is connected and that circuit breakers or fuses are not tripped. Ensure the motor and control box are wired per the wiring diagram. Replace the pushbutton operator or contact block if needed. If there is an overload relay, push the RESET button. Compare the customer power supply to the motor and control box ratings. Make sure all wires are correctly and solidly connected in the control box, motor junction box, and pit wall junction box. Check the interconnect limit switch and ARTD cam to ensure they are functional. Lastly, let the motor cool down in case the internal thermal overload has tripped; replace the motor if necessary.

  Try raising the unit to unlock the velocity fuse, then cycle it 5 to 10 times until the fuse no longer locks up. Readjust the shuttle valve and cycle the unit similarly. Remove any weight from the platform. Check for and remove any materials lodged around the leveler. Ensure the ARTD cam and restrictor limit switches are working correctly. Drain the oil from the power unit, hoses, and cylinders, replacing it with fresh oil, and verify that the suction filter in the tank is not clogged.
