IMPORTANT PRECAUTIONS
WARNING: To reduce the risk of serious injury, read the following important precautions
before using the weight system.
1. Read all instructions in this manual and in
the accompanying literature before using the
weight system.
2. It is the responsibility of the owner to ensure
that all users of the weight system are adequately informed of all precautions.
3. The weight system is intended for home use
only. Do not use the weight system in any
commercial, rental, or institutional setting.
4. Use the weight system only on a level surface. Cover the floor beneath the weight system to protect the floor.
5. Make sure all parts are properly tightened
each time the weight system is used.
Replace any worn parts immediately.
6. Keep children under 12 and pets away from
the weight system at all times.
7. Keep hands and feet away from moving parts.
8. Always wear athletic shoes for foot protection.
9. The weight system is designed to support a
a maximum user weight of 250 pounds.
10. Always stand on the foot plate when performing an exercise that could cause the
weight system to tip.
11. Never release the press arm, butterfly arms,
leg lever, leg press plate, lat bar, ab strap, or
nylon strap while weights are raised; the
weights will fall with great force.
12. Always disconnect the lat bar from the
weight system when performing an exercise
that does not use the lat bar.
13. Make sure that the cables remain on the pulleys at all times. If the cables bind while you
are exercising, stop immediately and make
sure that the cables are on all of the pulleys.
14. If you feel pain or dizziness at any time while
exercising, stop immediately and begin cooling down.
15. The warning decal shown
here has been placed on
the weight system in the
location shown on page
4. If a decal is missing or
illegible, please call tollfree 1-800-999-3756,
Monday through Friday,
6 a.m. until 6 p.m.
Mountain Time, to order a
free replacement decal.
Place the decal on the

ASSEMBLY
Make sure that you have the following tools:
• Two adjustable wrenches
• One standard screwdriver
• One phillips screwdriver
• One rubber mallet
•You will also need grease or petroleum jelly, a
small amount of soapy water, and 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.
How to Identify Parts
To help you identify the small parts used in assembly,
a P
ART 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 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 that
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?
If you have questions after reading the assembly
instructions, please call 1-800-4-MY-HOME
®
(1-800-469-4663).
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 hardware needed for each stage is packaged in separate 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 dispose of the packing materials until assembly is completed.
Make Assembly Easier
Everything in this manual is designed to
ensure that the weight system can be assembled successfully by anyone.
Before beginning assembly, make sure to
read the information on this page. This
brief introduction will save you much more
time than it takes to read it.
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
weight stations to the weight stacks.
Seat Assembly—During the final stage, you will
assemble the seats and the backrests.
1. Before beginning, be sure that you have read
and understood the information on page 5.
