1.
With the dumbbell handle set in the dumbbell base, turn the adjustment knobs
to the number 4. When you fully and correctly make the number selection, you
can feel the adjustment knob move into a notch (known as a detent). You will
also hear a small, but audible, click at the detent location for each number.
2.
Pull the handle vertically from the base and all the weight plates will stay
in the base.
3.
With the handle removed from the base, hold one adjustment knob with your
other hand and carefully try to turn the knob. The knob should not turn. A locking
pin in the mechanism engages the rotational assembly when the unit is removed
from the base. Do this test with all adjustment knobs.
Do not use too much force to try to turn the locked adjustment knob. Too much
force can damage the locking mechanism.
4.
After you make sure that the locking mechanism operates correctly, put the
dumbbell handle back and set it fully into the base assembly.
5.
With the handle back in the base, turn the adjustment knob to a position that is between the numbers 4 and 10. This is an incomplete weight selection where
the adjustment knob has not fully made a weight selection and the knob is between the selection detents (clicks).
6.
With the selection knob in this incorrect position, carefully try to lift the handle to remove it from the base. You should find that the handle is locked to
the base and cannot be removed with light pressure, as it usually can.
7.
Change the adjustment knob to a full and correct weight selection and make sure that the dumbbell handle can again be removed.
8.
Repeat this test for all adjustment knobs.
9.
Make sure the dumbbell handle assembly is properly tightened. To do this, set the adjustment knobs to 4 pounds and remove the handle assembly from the
base. Hold the adjustment knobs, and push and pull the knobs to and away from the handle grip. The knobs should not move freely and all of the selection
discs should feel tightly connected.
10.
The test of the locking mechanism function is now complete. We suggest that you repeat this test monthly to make sure that the locking mechanism
operates correctly.

Do not engage the locking mechanism and use the handle to try to lift the dumbbell and base together. To lift the dumbbell and base together, engage the
locking mechanism and hold the base assembly.
