Step1: Put the dumbbell in a safe, obstacle - free space for work.​ Step2: Remove Dumbbell Plates-Start from one end, take off each dumbbell plate carefully. Step3: Inspect Dumbbell Plates and Grooves​ Step4: Re - install Dumbbell Plates​ Align the first plate with the groove at one end of the bar and slide it in fully and centered. Install all plates this way, keeping the spacing even. Do the same for the other end, with the same number and weight of plates.​ Step5: Test Stability​ Hold the middle of the bar with both hands, lift the dumbbell, and let it hang. Feel for balance and check for shaking or tilting. You can also gently shake the dumbbell in different directions. A stable feel means the installation is better.​</p>
