Getting to know your Nautilus

SelectTech Dumbbells
®
The Nautilus SelectTech ND 552 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.
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 depressed into the base. 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 5 to 52.5
lbs (2.27kg to 23.9kg) on both
adjustment knobs. To properly
select a given weight (20 lbs [9kg]
for example) , both adjustment
knobs should be rotated until 20
is aligned with the arrow located
on the outward edge of the
Nautilus nameplate (Fig.1).

4. After confirming the proper rotational function of the adjustment
knob, turn each adjustment so that the number 5 is aligned with
the arrow in the Nautilus
Weight will increment in the following 15 steps:

5. With both adjustment
knobs set to 5, 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 5 lbs (2.27 kg).
6. You may increase the selected weight by rotating each
adjustment knob clockwise.
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.
8. When either returning or removing the dumbbell to or from the
base, do so in a vertical motion, perpendicular to the base. Try
not to tilt the dumbbell or move it laterally (parallel to the base)
until it is fully clear of the unselected weight plates.
