  If your QAL Medical Equipment displays error codes E1, E2, E3, E4, E6, E7, E8, E12, E13, E14, E15, E16, or E18, this could be due to several reasons. It might be out of calibration, in which case you should re-calibrate the unit following the calibration procedures. Alternatively, there could be a Main PCB failure (replace the PCB), a Controller cable break (replace the Controller cable), or a Controller PCB failure (replace the Controller).

Why is my QAL Medical Equipment experiencing mechanical binding or jerking?

  George HarperAug 19, 2025
  If your QAL Medical Equipment is experiencing mechanical binding or jerking, the cause might be insufficient lubrication on the track, ballscrew, and track seals. To resolve this, use a light lithium-based lubricant, such as Lubriplate #105, on the tracks and ballscrews, and apply a silicone spray on the track seals. Other potential causes include a bearing bracket assembly failure (replace the bearing bracket assembly), ballscrew failure (replace the ball screw assembly), U-Bracket/Slider Assembly failure (replace the U-bracket/slider assembly bracket assembly), or motor failure (replace the motor).
