7. The dumbbell handle and weight plates are symmetrical.
This means that one may insert the handle 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 Nautilus ®
Customer Service for repair information.

Getting to know your Bowflex ® SelectTech ®
Dumbbells
The Bowflex ® SelectTech ® dumbbells are shipped fully assembled,
one dumbbell to a box. 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 assure
that all aspects of the dumbbell are performing according their
specifications.
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, push down slightly on the handle assembly
to make sure it is fully depressed into the base.
2. Rotate each adjustment knob several full rotations
to make sure it is turning freely–do this 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. You will notice that there are
weight increments from 10 to 90
lbs on both adjustment knobs.
To properly select a given
weight (20 lbs for example),
both adjustment knobs should
be rotated until 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 just
the handle from the
base, leaving all of
the weight plates
standing in the base
(Fig. 2.). The handle
without plates
represents the starting
weight of 10 lbs.
6. You may increase the selected weight by rotating each
adjustment knob clockwise.
