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.
9.The weight system is designed to support a maximum user weight of 300 pounds.
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.
15.Always disconnect the lat bar from the 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.
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 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.
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. 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 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 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 these assembly instructions, please call 1-800-4-MY-HOME® (1-800-469-4663).
