Dumbbell locking mechanism test
®
After replacing any part of your Bowflex
before using your Dumbbell for any exercises:
This is a functional test of the weight plate locking mechanism.
1. With the dumbbell handle set in the dumbbell base, turn both adjustment knobs to the lowest
number (Figure 1). You will know you have fully and correctly selected the number when you feel
the adjustment knob settle into a notch (known as a detent). You will also hear a slight, but audible,
clicking noise that corresponds with the detent locations for each number.
2. You should be able to withdraw the handle from the base leaving all the weight plates behind
(Figure 2).
3. With the handle removed from the base, grab one adjustment knob with your other hand and firmly
attempt to turn the knob; the knob should not rotate.
4. Place the dumbbell back into the base, and turn the adjustment knob to the next lowest weight
setting. Lift the dumbbell from the base approximately 1 inch (2.5 cm).
5. With the handle still above the base, grab one adjustment knob with your other hand and firmly
attempt to turn the knob; the knob should not rotate. A locking pin in the mechanism will have
engaged the rotational assembly when the unit was withdrawn from the base. Perform this test with
all adjustment knobs.
6. Repeat this test for all weight settings on your dumbbells.
If any of the knobs rotate outside of the cradle, do not use the dumbbell, and contact your
Bowflex
retailer.
