TABLE OF CONTENTS

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 a com­mercial, rental, or institutional setting.

4. Use the weight system only on a level sur­face. Cover the floor or carpet beneath the
weight system to protect the floor or carpet.

5. Make sure all parts are properly tightened
each time you use the weight system.
Replace any worn parts immediately.

6. Keep children under the age of 12 and pets
away from the weight system at all times.

7. The weight system is designed to be used by
no more than two people at a time.

8. Always wear athletic shoes for foot protec­tion when exercising.

9. Keep hands and feet away from moving parts.

10. Make sure the cables remain on the pulleys

exercising, stop immediately and make sure
the cables are on all of the pulleys.

11. Always stand on the foot plate when perform­ing an exercise that could cause the weight
system to tip.

12. Never release the press arms, butterfly arms,

BEFORE YOU BEGIN

5

Make sure 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 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.

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 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 our HELPLINE at

1-800-736-6879.

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 take time. 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.

Make Assembly Easier for Yourself

Everything in this manual is designed to
ensure that the weight system can be assem­bled successfully by anyone. Before begin-

ning 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
arms to the weights.

Seat Assembly—During the final stage you will
assemble the seats and the backrests.
