Operation
Given the importance of this locking mechanism, it is critical that you understand how it operates, and periodically test it to make
sure it is functioning correctly.
Testing proper locking mechanism function
1. With the dumbbell handle set in the dumbbell base, turn both adjustment knobs to the
number 2. 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.
3. With the handle removed from the base, grab one adjustment knob with your other hand and
gently 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have engaged the rotational assembly when the unit was withdrawn from the base.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.
Do not use too much force to try to turn the locked adjustment knob. Too much force can damage the locking mechanism.
4. After confirming the proper function of the locking mechanism as described above, return and fully insert the dumbbell
handle back into the base assembly.
5. With the handle back in the base, turn the adjustment knob on one side to a position that is between the numbers 2 and 3.
This represents an incomplete weight selection where the adjustment knob has not fully selected a weight and the knob is
in-between the selection detents (clicks).
6. With the selection knob in this improper position, gently attempt to lift up on 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 can normally.
7. Return the improperly selected adjustment knob to a full and proper weight selection and assure that the dumbbell handle
can once again be removed.
8. Repeat this test for all adjustment knobs.
9. Assure the entire dumbbell handle assembly is properly tightened. Do this by setting the adjustment knobs to 2 and
removing the handle assembly from the base. Grab both adjustment knobs and very slightly push and pull the knobs toward
and away from the handle grip. The knobs should not exhibit free play and all of the selection discs should feel tightly
connected.
10. You have now tested the function of the locking mechanism. We suggest 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 use the lift handles molded into the base assembly.
If the dumbbell locking mechanism operates unsatisfactorily in the test procedure above, do the following:
1. Stop use of the product immediately until approved service is available.
2. Contact your Bowflex
®
retailer for service.
