Lift knob malfunction on G50 arm
What the thread found
- The lift knob on the rear section near the socket block can become stuck or jammed if adjusted while the arm is unloaded.
- Adjusting the lift mechanism should only be done when the arm is carrying a load and the spring is positioned at approximately 90 degrees to the lift adjuster.
- A jammed lift knob after attempted unloaded adjustment indicates internal damage requiring professional repair.
Depends on
- This specifically concerns the G50 arm model.
- The claim about unloaded adjustment damage is based on forum discussion rather than official documentation.
- Whether all lift knob failures result from unloaded adjustment remains unclear from the thread.
