SelectTech Dumbbell locking mechanism test
After replacing any part of your Bowflex
procedures 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will have engaged the rotational assembly when the unit was withdrawn from the base.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.
