Solution
1. Make certain that both adjustment knobs are set directly to
the number 5.
2. Make certain that all of the weight plates have the "selection
tongue" facing away from the dumbbell grip. If one or more of
these are backwards (selection tongue facing inward toward
grip), the handle can get blocked, and the plates may wedge
into the handle.
1. Check to see if you have selected different weights on each side
of the dumbbell (for example one adjustment knob is set to 5
and the other is set to 7 .5). If this is the case, you must replace
the dumbbell in the base with the same orientation in which
was withdrawn. This is to allow the plates to settle back into
the correct and vacant openings in the base.
2. Verify that the plates not selected (those plates remaining in
the dumbbell base) are in their correct spots and have not
been moved to a different support slot. This may be blocking
the dumbbell from fitting back into the base.
3. See solution #2 from problem above.
1. Check to assure that the dumbbell handle is fully depressed
into the dumbbell base. If not fully depressed, the locking
mechanism will not be released and may be keeping the
adjustment knobs from rotating.
2. Check to see if any weight plates have been put into the base
assembly backwards with the "support tongue" facing the
grip of the dumbbell handle. All weight plates must have the
selection tongue facing away from the grip of the dumbbell
handle.
3. Check to see if there is any dirt, debris or other obstruction
in the dumbbell base. You may need to remove the weight
plates from the base to accomplish this check. Remember to
put each weight plate back in its appropriate location with the
selection tongue facing away from the dumbbell grip.
4. Depress the locking tab in the handle and test rotation. If the
silver locking tab in the base is loose, replace the base.
