ORERATION

Do not drop the dumbbell. Dropping the dumbbell will damage the weight plates and/or the locking mechanism, and can cause the weight plates to disengage (drop) from the handle without warning. This can cause serious injury, and will void the warranty.

1. After removing the dumbbell from its protective packaging, inspect the products and packaging material for any damages.
2. Push down slightly on the handle assembly to make sure it is fully seated in the base. Rotate each adjustment knob several full rotations to make sure it turns freely in both directions. Make sure there is a click at each weight increment of the adjustment knob. This click will help you locate the proper alignment to select a given weight increment.
3. The weight increments range from 10 lbs to 90 lbs (4.5 to 41 kg) on both adjustment knobs. To properly select a given weight (20 lbs [9 kg] for example), rotate both adjustment knobs until that number (20) is aligned with the arrow located on the outward edge of the BowFlex nameplate (Fig.1).

4. After confirming the proper rotational function of the adjustment knob, turn each adjustment so that the number 10 is aligned with the arrow in the BowFlex nameplate.
5. With both adjustment knobs set to 10, pull the handle straight up from the dumbbell. This will remove only the handle from the base, and let all of the weight plates stay in the base (Fig. 2). The handle without plates gives the initial weight of 10 lbs (4.5 kg).

6. You may increase the selected weight by rotating each adjustment knob clockwise.
7. The dumbbell handle and weight plates are symmetrical. The handle is inserted with either end facing the user, provided that you have selected the same weight number on both ends of the dumbbell.
NOTICE: When you remove the dumbbell from the base or return it to the base, use a vertical motion, perpendicular to the base. Do not tilt the dumbbell or move it laterally (parallel to the base) until it is fully clear of the unselected weight plates.

Do not lean on the dumbbell handles or use them to support your body weight , such as using them as a base to perform a push up. Doing so will damage the weight plates and/or the locking mechanisms, and can cause the weight plates to disengage (drop) from the handle without warning.
This can cause serious injury, and will void the warranty.
Inspect the dumbbells prior to each use. Do not use a dumbbell with worn or damaged parts. Contact BowFlex Customer Service for repair information.

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.

Function
The locking mechanism provides two key functions:

1. The mechanism will only allow the adjustment knobs to be rotated when the dumbbell handle is completely inserted and engaging the dumbbell base.
2. The mechanism is designed to lock the dumbbell handle to the base if either adjustment knob 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 dumbbell handle set in the dumbbell base, turn both adjustment knobs to the number 10. 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 10 and 15. 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 10 pounds 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.

 

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 or contact Bowflex directly by phone at 1-800-628-8458 for service.

 

MAINTENENCE

BowFlex SelectTech Dumbbell maintenance

Equipment must be regularly examined for damage and repairs. The owner is responsible to make sure that regular maintenance is done. Worn or damaged components must be replaced immediately or the equipment removed from service until the repair is made. Only manufacturer supplied components can be used to maintain and repair the equipment.

The BowFlex SelectTech Dumbbell is a very low maintenance product. However, there are steps that you should take to keep the product performing and looking its very best.

1. Should your SelectTech Dumbbell handle assembly, plates or base become soiled you may clean them with a cloth lightly dampened with warm water and a small amount of mild soap. Wipe dry with a separate cloth.
2. The SelectTech Dumbbell is internally lubricated and will not require further internal lubrication. The contact between weight plates and selection discs is not lubricated but has naturally low friction. This generally will not require any lubrication. Should you feel it necessary to lubricate the weight plates and/or selection discs, use only a silicon lubricant, preferably “food grade”.

Do not use any solvents, harsh detergents, chemicals or bleach on this product − doing so may damage the materials, resulting in degradation of the product’s performance or strength.
Do not attempt to disassemble the dumbbell handle or base assembly. These items are not designed to be user serviced. Doing so will void the manufacturers warranty. Contact Bowflex directly for service.

 

TROUBLESHOOTING

 

SelectTech Dumbbell locking mechanism test
After replacing any part of your BowFlex SelectTech Dumbbell, be sure to perform the following 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 Bowflex Customer Service.
