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 assembly, 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 packages 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 the assembly of our products can be completed successfully by anyone. However, it is important to recognize that your new equipment is a
sophisticated product with many small parts. The
assembly process will take time—possibly several
hours. Most people find that by setting aside plenty of time, and by deciding to make the task
enjoyable, they can avoid feeling rushed or overwhelmed. 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 of Parts
Tighten all parts as you assemble them, unless
instructed to do otherwise.
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):
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.
• Two (2) adjustable wrenches
Unpacking the Box
• One (1) phillips screwdriver
To make the assembly process as smooth as possible, 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.
• One (1) rubber mallet
Important: Wait until you begin each assembly
stage to open the parts bag labeled for that
assembly stage.
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.
• One (1) standard screwdriver
• Lubricant, such as grease or petroleum jelly,
and soapy water
• Tape, such as clear tape or masking tape
The Four Stages of the Assembly Process

ADJUSTMENT, beginning on page 20 of this manual.
Before using the home gym system, pull each cable a few times to be sure that the cables move smoothly
over the pulleys. If one of the cables does not move smoothly, find and correct the problem. IMPORTANT: If
the cables are not properly installed, they may be damaged when heavy weight is used. If there is
any slack in the cables, you will need to remove the slack by tightening the cables. See TROUBLESHOOTING AND MAINTENANCE on page 22.
Cable Diagram
The Cable Diagram below shows the proper routing of the Short Cable (23), the Medium Cable (86) and the
Long Cable (58). The numbers show the correct route for each cable. Make sure the Cables are routed correctly, that the Pulleys move smoothly and that the Cable Traps do not touch or bind the Cables.
Incorrect cable routing can damage the weight system.

Adjustment
The instructions below describe how each part of the home gym system can be adjusted. Refer to the exercise
poster accompanying this manual to see how the home gym system should be set up for each exercise.
IMPORTANT: When attaching the lat bar or nylon strap, make sure that the attachments are in the correct starting position for the exercise to be performed. If there is any slack in the cables or chain as an
exercise is performed, the effectiveness of the exercise will be reduced.
Changing the Weight Setting
To change the weight setting of the weight stack, insert a
Weight Pin (26) under the desired Weight (25). Be sure to
insert the Weight Pin until the bent end of the Weight Pin
is touching the Weights, and turn the bent end downward.
The weight setting of the weight stack can be changed
from 6.5 pounds to 106.5 pounds, in increments of 12.5
pounds. Note: Due to the cables and pulleys, the
amount of resistance at each exercise station may
vary from the weight setting. Use the WEIGHT
RESISTANCE CHART on page 23 to find the approximate amount of resistance at each weight station.

indicated pins on the Butterfly Upright (42). Attach the
Butterfly Seat Frame to the Butterfly Upright with the
5/16” x 2 3/4” Carriage Bolt (14) and the Seat Knob (40).
42
For some exercises, the Butterfly Seat Frame (36) must
be removed. First, be sure that the chain is not attached
to the leg lever. Next, remove the Seat Knob (40) and the
5/16” x 2 3/4” Carriage Bolt (14) from the Seat Frame. Lift
the Seat Frame off the Butterfly Upright (42).

Weight Resistance Chart
This chart shows the approximate weight resistance at each station. “Top” refers to the 6.5 lbs. top
weight. The other numbers refer to the 12.5 lbs. weight plates. Note: The actual resistance at each
weight station may vary due to differences in individual weight plates, as well as friction between
the cables, pulleys, and weight guides.

Trouble-shooting and Maintenance
Inspect and tighten all parts each time you use the home gym system. Replace any worn parts
immediately. The home gym system can be cleaned using a damp cloth and mild non-abrasive
detergent. Do not use solvents.
Tightening the Cables
1
Woven cable, the type of cable used on the home gym
system, can stretch slightly when it is first used. If there is
slack in the Cables before resistance is felt, the Cables
should be tightened. Insert the Weight Pin (26) under one
of the indicated Weights (25). Slack can be removed from
the Cables by tightening the 1/4” Nylon Locknuts (2) at
the end of the Short Cable (23) (see drawing 1) and at
the end of the Long Cable (58) (see drawing 2). To do this
you may need to remove the Small “U”-Bracket (67) from
the Weight Tube (not shown) or remove the 3 1/2” Pulley
(15) from the Long “U”-Bracket (57). Make sure that the
Cables are not too tight or the Top Weight (76) will be lifted off the weight stack.
23
67
76
2
25
26
Additional slack can be removed by moving the 3 1/2”
Pulley (15) to the other hole in the “I”-Brackets (81) as
shown in the upper inset drawing. Remove the 3/8” Nylon
Locknut (21) and the 3/8” x 2” Bolt (12) from the Cable
Trap (66), Pulley and “U”-Bracket. Re-attach the Pulley
and Cable Trap. Be sure that the Cable trap is in the
proper position and that the Cable and Pulley move
smoothly.
2
81
12
Slack can also be removed by moving the 3 1/2” Pulley
(15) to the other hole in the Long “U”-Bracket (57) as
shown in the lower inset drawing. Remove the 3/8” Nylon
Locknut (21) and the 3/8” x 2” Bolt (12) from the Cable
Trap (66), Pulley and “U”-Bracket. Re-attach the Pulley
and Cable Trap. Be sure that the Cable trap is in the
proper position and that the Cable and Pulley move
smoothly.
66

Note: If a Cable tends to slip off the Pulleys often, the
Cable may have become twisted. Remove the Cable
and re-install it.
