If you're having issues with weights not staying in the base or not picking up correctly, we recommend:
If the dumbbells still aren't attaching properly, inspect the equipment for any interfering objects.
Make sure the unit is clean from debris and obstructions.
Make sure the handle is seated fully and the dumbbell weights are in the correct arrangement.
Check to make sure the base and dumbbell have power.
Remove the dumbbells and make sure there are no obstructions in the base that would prevent the push rods from moving up and down. Cycle through all of the weight selections to make sure all the push rods are activating. The push rods are indicated with arrows in the image below.
Check the weights to make sure the latch and plunger have freedom of movement.
Check the weights to make sure the latch pocket is free from debris or obstructions.
