The plates fall out of my adjustable dumbbell when I lift it up

There are multiple reasons as to why plates can fall out of your dumbbell when lifted up. Such reasons may be:

• Your plates are inserted incorrectly. In this case, please refer to the weight plate setup in your instruction manual.
• You are lifting the dumbbells out of the base at an angle, rather than up straight as is necessary.
• Your plates are dirty or soiled, and as a result need cleaning.
