4. Operating Instructions: Weight Adjustment

The DH FitLife Adjustable Dumbbells feature a simple and quick weight adjustment mechanism.

1. Place Dumbbell in Tray: Ensure the dumbbell is fully seated in its storage tray. The weight selection mechanism can only be operated when the dumbbell is in the tray.

5. Return Dumbbell: After your exercise, carefully place the dumbbell back into the tray, ensuring it is fully seated before attempting to change the weight again.
