How to Identify Parts
To help you identify the small parts used in assembly,
a PART IDENTIFICATION CHART is included in the
center of this manual. Lay the chart on the floor and
use it to easily identify parts during each assembly
step. Note: Some small parts may ha e been pre-
attached. If a part is not in the parts bag, check

Questions?
If you have questions after reading the assembly
instructions, please call our Customer Service
Department toll-free at 1-800-999-3756, Monday
through Friday, 6 a.m. until 6 p.m. Mountain Time.
Assembly Requires Two Persons
For your convenience and safety, assemble the
weight system with the help of another person.
Set Aside Enough Time
Due to the many features of the weight system, the
assembly process will require several hours. By
setting aside plenty of time and by deciding to
make the task enjoyable, assembly will go smoothly.
Select a Location for the Weight System
Because of its weight and size, the weight system
should be assembled in the location where it will be
used. Make sure that there is enough room to walk
around the weight system as you assemble it.
How to Unpack the Box
To make assembly easier, we have divided the
assembly process into four stages. The small hard-
ware needed for each stage is packaged in sepa-
rate bags. Important: Wait until you begin each
stage to open the parts bag(s) for that stage.
Place all parts of the weight system in a cleared
area and remove the packing materials. Do not dis-
pose of the packing materials until assembly is com-
pleted.
Make Assembly Easier
Everything in this manual is designed to
ensure that the weight system can be assem-
bled successfully by anyone.

brief introduction will sa e you much more
time than it takes to read it.
