Understanding and testing the locking mechanism function
The Bowflex SelectTech Dumbbell features an exclusive locking mechanism designed to ensure proper
® ®
and complete selection of the weight plates as well as to ensure weight plate retention during the workout.
Fully understand the function of this mechanism and do tests of the mechanism regularly to
make sure it operates correctly.
After replacing any part of your Bowflex
procedures before using your Dumbbell for any exercises:
Function
The locking mechanism provides two key functions:
1. The mechanism will only allow the Adjustment Grip to be rotated when the Handle Assembly is completely inserted and engaging the
Dumbbell Base.
2. The mechanism is designed to lock the Handle Assembly to the base if the Adjustment Grip is not fully engaging the selected weight plates.
Purpose
The locking mechanism serves two important purposes:
1. The mechanism will prevent deselecting (dropping) weight plates from the dumbbell when it is NOT in the Dumbbell Base.
2. The mechanism will prevent partial selection of the weight plates in which the plates are not fully supported and the locking pin is not fully
engaged.
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 Handle Assembly set in the Dumbbell Base, turn the Adjustment Grip to the number 5. You will know you have fully and correctly
selected the number when you feel the Adjustment Grip 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 Assembly from the Base leaving all the weight plates behind.
3. With the Handle Assembly removed from the Base and on the ground, gently attempt to turn the Adjustment Grip. The Adjustment Grip
should not rotate. A locking pin in the mechanism prevents the assembly from rotating when withdrawn from the Base.
Do not use too much force to try to turn the locked Adjustment Grip. Too much force can damage the locking mechanism.
4. After confirming the proper function of the locking mechanism as described above, fully insert the Handle Assembly back into the Dumbbell
Base.
5. With the Handle Assembly back in the Base, turn the Adjustment Grip to a position that is between the numbers 10 and 12.5. This
represents an incomplete weight selection where the Adjustment Grip has not fully selected a weight and is in-between the selection detents
(clicks).
6. With the Adjustment Grip in this improper position, gently attempt to lift up on the Handle Assembly to remove it from the Base. You should
find that the Handle Assembly is locked to the Base and cannot be removed from it.
If the Handle Assembly comes free from the Base with the partial weight selection, do not use the Dumbbell and contact Customer
Care.
7. Return the improperly selected Adjustment Grip to a full and proper weight selection and confirm that the Handle Assembly can once again
be removed.
