Your BRAINGAIN Adjustable Dumbbells come pre-assembled. Follow these steps for initial setup:

1. Unpacking: Carefully remove the dumbbells and their storage bases from the packaging.
2. Placement: Place the storage bases on a flat, stable, and non-slip surface where you intend to exercise. Ensure there is enough clear space around the dumbbells for safe movement.
3. Dumbbell Placement: Place each dumbbell securely into its corresponding storage base. Ensure all weight plates are properly seated within the base.
4. Initial Check: Before first use, gently twist the handle to ensure the weight selection mechanism moves smoothly and engages correctly.

4. Operating Instructions

Follow these instructions to safely adjust and use your BRAINGAIN Adjustable Dumbbells:

4.1. Adjusting Weight

1. Place Dumbbell in Base: Ensure the dumbbell is fully seated in its storage base.
2. Select Weight: Grip the handle firmly. Rotate the handle clockwise or counter-clockwise to align the desired weight setting with the indicator on the dumbbell. You will hear a "click" as the mechanism engages.
3. Verify Engagement: Before lifting, gently pull the handle upwards a small amount to ensure the selected weight plates are securely attached and the remaining plates are left in the base.
4. Lift and Use: Once the weight is securely selected, lift the dumbbell straight up from the base.

The 23.5 kg model offers weight adjustments from 4 kg to 23.5 kg in 1.5 kg increments.
