that all users of the weight system are ade-
quately informed of all precautions.
4. The weight system is intended for home use
only. Do not use the weight system in any
commercial, rental, or institutional setting.
5. Keep the weight system indoors, away from

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.
ASSEMBLY
To make assembly easier, carefully read the
following information and instructions:
•Assembly requires two persons.
• Because of its size, the weight system should be
assembled in the location where it will be used.
Make sure that there is enough clearance to walk
around the weight system as you assemble it.
• 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 hardware kits. Place all parts of the
weight system in a cleared area and remove the
packing materials. Do not dispose of the packing.
• Place all parts in a cleared area and remove the
packing materials. Do not dispose of the packing
materials until assembly is completed.
• For help identifying small parts, use the PART
IDE TIFICATIO CHART on pages 5 and 6.
• As you assemble the weight system, make sure
all parts are oriented as shown in the drawings.
•Tighten all parts as you assemble them, unless
instructed to do otherwise.
• Assembly requires the included hex key and
grease and the following tools (not included):
two adjustable wrenches
one rubber mallet
one standard screwdriver
one Phillips screwdriver
Assembly may be more convenient if you have a
socket set, a set of open-end or closed-end
wrenches, or a set of ratchet wrenches.
