ASSEMBLY
Make Assembly Easier
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.
Make sure that 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 masking tape.
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.
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 easier, we have divided the
assembly process into four stages. The small hardware needed for each stage is packaged in separate bags.
stage to open the parts bag(s) 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.
Important: Wait until you begin each
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,
a PART IDENTIFICATION CHART is included in the
center of this manual. Lay 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.
