1. Make sure that the dumbbell handle is fully pushed into the dumbbell base. If not fully set into the base,
the locking mechanism will not be released and will prevent the adjustment knobs from turning.
2. Make sure that the weight plates are seated correctly in the base assembly.
3. Inspect the dumbbell base for dirt, debris or other unwanted material. If necessary, remove the weight
plates from the base to do this check. Remember to put each weight plate back in its correct location.
1. Make sure that the plates that are still in the dumbbell base are in their correct spots and not moved to
different support slots.
