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.

other Pulley until the cables are tight.
TROUBLE-SHOOTING AND MAINTENANCE
TIGHTENING THE CABLES
If a cable slips off the pulleys often, the cable may have become twisted. Remove the cable and re-install
it. If the cables need to be replaced, see ORDERING REPLACEMENT PARTS on the back cover of this manual.
The type of cable used on the weight 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. Slack can be removed from the cables in two
different ways:
