The chart to the right is a quick reference to determine the
amount of weight offset to one side of the dumbbell.
The symbol + indicates the amount of offset weight on the
heavier side of the dumbbell.
Although you can continue to increase the amount of weight
offset, it is not generally necessary to offset the weight more
than 20 lbs.
Difference Offset
5 lbs + 2.5 lbs
10 lbs + 5 lbs
15 lbs + 7.5 lbs
20 lbs + 10 lbs
25 lbs + 12.5 lbs
30 lbs + 15 lbs
35 lbs + 17.5 lbs
40 lbs + 20 lbs
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 rag
lightly dampened with warm water and a small amount of
mild soap. Wipe dry with a separate rag.
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”.
