Before You Start

The dumbbells are shipped fully assembled. After carefully removing the dumbbell from its box, there are some initial steps that should

betakentofamiliarizeyouwiththefunctionoftheproduct,andtomakesurethatallfeaturesofthedumbbelloperatecorrectly.

Donotdropthedumbbell.Droppingthedumbbell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.

Adjustable Dumbbell Maintenance:

1. If your dumbbell handle assembly, plates or base become dirty, you can 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 adjustable dumbbell is internally lubricated and will not require more internal lubrication. The contact between weight plates

and selection discs is not lubricated but has naturally low friction. Lubrication is usually not necessary. If you feel it is necessary to

lubricatetheweightplatesand/orselectiondiscs,useonlya“foodgrade”siliconlubricant.

Daily / Before Each Use:

Examine equipment. Make sure it looks in good condition and operates smoothly. If you ﬁnd damage, DO NOT

USE.

Daily / After Each Use:

Clean equipment with a clean, dry cloth. Do not use cleansers containing enzymes.

Weekly:

Clean equipment fully with a clean cloth lightly dampened with warm water and a small amount of mild soap.

Wipe dry with a separate cloth.

Touch up any scratches with touch-up paint to prevent rust, if necessary.

Monthly:

Examine the frame for signs of cracking or permanent bending. Do not use the equipment if you see this.

Contact your local Bowﬂex

distributor or vendor for service.

Troubleshooting

Problem Solution

Dumbbell handle does not fully go into base

when no plates are attached.

1. Make sure that the adjustment knobs are set directly to the number 4.

2. Make sure that the weight plates are seated correctly in the base assembly.

Dumbbell handle does not fully go into base

when plates are attached.

Make sure that the plates that are still in the dumbbell base are in their correct spots and not

moved to different support slots. This may be blocking the dumbbell from ﬁtting back into the

base.

Adjustment knob will not turn while handle is

in base.

1. Make sure that the dumbbell handle is fully pushed into the dumbbell base. If not fully set into

the base, the locking mechanism will not be released and will prevent the adjustment knobs from

turning.

2. Make sure that the weight plates are seated correctly in the base assembly.

3. Inspect the dumbbell base for dirt, debris or other unwanted material. If necessary, remove

the weight plates from the base to do this check. Remember to put each weight plate back in its

correct location.

Plates are not attached safely to the handle

and drop out.

Make sure that the plates that are still in the dumbbell base are in their correct spots and not

moved to different support slots.
