BASIC ASSEMBLY PRINCIPLES
Here are a few basic tips that will aid in the assembly of the Nautilus® NS75X. By using these
principles, you can simplify each process and save yourself extra time and effort.
1. To make the assembly process go faster, gather the pieces you need for each step and
thoroughly read the assembly instructions for that step prior to starting assembly for the step.
2. When tightening a locknut on a bolt, use a combination wrench to grip the locknut and ensure
that it is fastened securely.
3. When attaching two pieces, gently lift and look through the bolt holes to help guide the bolt
through the holes.
4. As a general rule, and for all bolts and nuts on your NS75X Bench, turn bolts or nuts toward
the right to tighten and left to loosen. Or you can remember the mnemonic: “Righty tighty, lefty
loosey.”
