Operating Instructions

Weight Adjustment

The HAKENO Adjustable Dumbbells feature a quick and easy weight adjustment system. You can change the weight of each dumbbell with a single hand while it is seated in its tray.

1. Place Dumbbell in Tray: Ensure the dumbbell is fully seated in its storage tray. The weight adjustment mechanism can only be operated when the dumbbell is correctly positioned in the tray.
2. Rotate Dial: Locate the red weight adjustment dial on each end of the dumbbell handle. Rotate both dials simultaneously to your desired weight setting. You will hear a "click" sound as the dial locks into each increment.
3. Verify Selection: Visually confirm that the selected weight number is clearly displayed on both dials. Gently lift the dumbbell to ensure only the selected weight plates are attached. If additional plates are lifted, reseat the dumbbell and re-adjust the dials.

Maintenance

• Cleaning: Wipe the dumbbells and trays with a damp cloth after each use to remove sweat and dust. Avoid using abrasive cleaners or solvents. The weight plates are coated to protect against sweat and moisture.
• Storage: Always store the dumbbells in their designated trays in a dry, cool place away from direct sunlight and extreme temperatures.
• Inspection: Periodically check all parts for signs of wear, damage, or loose components. Ensure the weight adjustment mechanism operates smoothly. If any issues are found, discontinue use and contact customer support.

Troubleshooting

Problem: Dumbbell does not pick up selected weight plates.

Solution: Ensure the dumbbell is fully and correctly seated in its storage tray. The weight adjustment dial must be rotated completely to the desired weight setting, and you should hear a distinct "click" indicating it is locked. Check for any obstructions between the plates or in the tray.

Problem: Dumbbell feels unbalanced or loose.

Solution: Reseat the dumbbell in the tray and re-adjust the weight dials. Ensure both dials are set to the exact same weight. Inspect the plates for any damage or deformation. If the issue persists, discontinue use.
