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 all
warnings on the weight system before using
the weight system. Use the weight system
only as described in this manual.
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. Keep the weight system indoors, away from
moisture and dust. Place the weight system
on a level surface, with a mat beneath it to
protect the floor or carpet. Make sure that
there is enough clearance around the weight
system to mount, dismount, and use the
weight system.
5. Inspect and properly tighten all parts regularly. Replace any worn parts immediately.
6. Keep children under 12 and pets away from
the weight system at all times.
7. Always wear athletic shoes for foot protection while exercising.
8. Keep hands and feet away from moving parts.
10. The weight system is designed to be used
only with the included weight. Do not use the
weight system with dumbbells or any other
type of weight to increase the resistance.
11. Make sure that the cables remain on the pulleys at all times. If the cables bind as you are
exercising, stop immediately and make sure
that the cables are on the pulleys. Replace all
cables at least every two years.
12. Always secure the weight stack with the lock
pin and lock after exercising to prevent
unauthorized use of the weight system (see
LOCKING THE WEIGHT STACK on page 24).
13. Always stand on the foot plate when performing an exercise that could cause the
weight system to tip.
14. Never release the arms, leg lever, lat bar, leg
press, ab strap, or handle while weights are
raised. The weights will fall with great force.
Always disconnect the lat bar from the
15.
weight system when performing an exercise
that does not use the lat bar.
16. If you feel pain or dizziness at any time while
exercising, stop immediately and begin cooling down.
The weight system is designed to support a
9.
maximum user weight of 300 pounds.
WARNING: Before beginning this or any exercise program, consult your physician. This
is especially important for persons over the age of 35 or persons with pre-existing health problems.
Read all instructions before using. Sears assumes no responsibility for personal injury or property
damage sustained by or through the use of this product.

ASSEMBLY
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.
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
• 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 P
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.
ART IDENTIFICATION CHART
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.
