BEFORE YOU ASSEMBLE
Note: Throughout this manual, all references to the left or right
side and to the front or back are made as if you were standing on
a level surface and facing the Adjustable Tower.
Basic Assembly Principals
Here are few basic assembly tips that can make assembly of your
Nautilus®Commercial Free Weights Adjustable Tower quick and
easy.
1. You can make the assembly process go faster by gathering the
pieces you need for each step prior to starting the step.
2. As a general rule, and for all fasteners on your Nautilus®
Commercial Free Weights Adjustable Tower , turning toward
the right will tighten, turning towards the left will loosen. An
easy way to remember this is by remembering the expression,
“Lefty loosey, righty tighty.”
3. Not all of the tools needed to assemble your Nautilus®
Commercial Free Weights Adjustable Tower , are provided.
Refer to the Tool List. You may find the use of a utility knife or
scissors beneficial during the unpacking and assembly process.
4. It is recommended that you use two people to assemble your
Nautilus® Commercial Free Weights Adjustable Tower .
Positioning Your Nautilus® Commercial Free Weights
Adjustable Tower
Take great care when moving your Commercial Free Weights
Adjustable Tower into place prior to assembly.
The Adjustable Tower is heavy and requires at least two people to
safely move from one location to another. Remove weights before
attempting to move the unit.
