ASSEMBLY

Make Assembly Easier for Yourself

Everything in this manual is designed to
ensure that the weight system can be assem-
bled successfully by anyone. Before begi n=
ning assembly, make sure to read the

information on this page. This brief intro-
duction will save you much more time than

it takes to read it.

Assembly Requires Two Persons

For your convenience and safety, assemble the
weight system with the help of another person.

Make sure you have the following tools:

* Two adjustable wrenches
* One standard screwdriver _ 1_h

= One phillips screwdriver
, One rubber mallet

, You will also need grease or petroleum jelly, a

small amount of soapy water, and clear tape or
masking tape.

Note: Assembly will be more convenient if you have

a socket set, a set of open-end or closed-end
wrenches, or a set of ratchet wrenches.

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.
You may want to assemble the weight system over

a couple of evenings.

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 as easy as possible, we have
divided the assembly process into four stages. The

parts needed for each stage are found in individual
bags. important: Wait until you begin each stage

to open the parts bag for that stage. Place all
parts of the weight system in a cleared area and

remove the packing materials. Do not dispose of
the packing materials until assembly is completed.

How to Identify Parts

To help you identify the small parts used in assembly,
we have included a PART IDENTIFICATION CHART

in the center of this manual. Place the chart on the

floor and use it to easily identify parts during each
assembly step. Note: Some small parts may have

been pre-attached. If a part is not in the parts
bag, check to see if it has been pre-attached.

How to Orient Parts

As you assemble the weight system, make sure all

parts are oriented exactly as shown in the drawings.

Tightening Parts

Tighten all parts as you assemble them, unless

instructed to do otherwise.

Questions?

instructions, please call 1-800-4-1VlY=HOME®

The Four Stages of the Assembly Process

Frame Assembly--You will begin by assembling
the base and the uprights that form the skeleton of
the weight system.

Arm Assembly--During this stage you will
assemble the arms and the leg lever.

Cable Assembly--During this stage you will
attach the cables and pulleys that connect the

arms to the weights.
Seat Assembly--During the final stage you will

assemble the seats and the backrests.
