Weight Change:
The basic procedure to change dumbbell weights is to simply open the locking screws (4” diameter disc with
knurled grip and 1” diameter partially threaded shaft) by turning the disc counterclockwise until the “OPEN”
arrow and notch points up toward the notch indicator on the handles. The handle notch is found on one side
of the square, chrome backing plates that are welded to the handle grips. The notch should always be the top
of the handle when set down before changing. When the arrow on the locking screw is pointed up at the
notch, this is the open position where you can pull the locking screw directly out of the handle.
