Assembly  
Note: This introduction will save you more time  
than it takes to read it!  
Identifying Parts  
To help you identify the small parts used in assem-  
bly, we have included a PART IDENTIFICATION  
CHART located in the center of this manual. Place  
the chart on the floor or work table and use it to  
quickly identify different parts as you open the pack-  
ages for each step. Note: Some small parts may  
have been pre-attached for shipping. If a part is not  
in the parts bag, check to see if it has been pre-  
attached.  
Making Things Easier for Yourself  
Everything in this manual is designed to ensure  
that our products can be assembled successfully  
by anyone. However, it is important to realize  
that your new equipment is a sophisticated prod-  
uct with many small parts. The assembly process  
will take time—possibly several hours. Most peo-  
ple find that by setting aside plenty of time, and  
by deciding to make the task enjoyable, assem-  
bly will go smoothly. You may want to complete  
the process over a couple of evenings.  
Orienting Parts  
As you assemble this product, be sure that all parts  
are oriented as shown in the drawings.  
Tightening Parts  
Tighten all parts as you assemble them, unless  
instructed to do otherwise.  
Some assembly steps require two people.  
Giving Yourself a Good Start  
Before you begin the assembly process itself, take  
the time to complete the steps outlined here.  
Lining Up the Tools  
Assembly requires the following tools (not included):  
• Two (2) adjustable wrenches  
• One (1) standard screwdriver  
• One (1) phillips screwdriver  
• One (1) rubber mallet  
Clearing the Workspace  
Clear a workspace that is large enough to hold all  
parts and allow you to walk all the way around the  
assembled equipment.  
Unpacking the Box  
To make the assembly process as smooth as possi-  
ble, we have broken it into separate stages. All parts  
used in each stage are found in individual packages  
in the shipping box. Place all parts in a cleared area  
and remove the packing materials. Do not dispose of  
the packing materials until assembly is completed.  
• Lubricant, such as grease or petroleum jelly,  
and soapy water  
Tape, such as clear tape or masking tape  
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.  
Important: Wait until you begin each assembly  
stage to open the parts bag labeled for that  
assembly stage.  
The Four Stages of the Assembly Process  
Frame Assembly  
Cable Assembly  
You will begin by assembling the base and the  
upright frames that serve as the skeleton of the  
equipment.  
This stage completes the cables and pulleys that  
connect the moving arms with each other and with  
the weights.  
Seat Assembly  
Arm Assembly  
This stage completes the press and butterfly arms  
that you operate while you are exercising.  
This final stage completes the seat and backrest  
that support your body while you are exercising.
