Important Safety Precautions
Prior to using this equipment, observe the following warnings.
1. Read and understand the complete Owner's
Manual for this accessory equipment. Refer to
your original Owner’s Manual for your Bowflex®
home gym for a list of general warnings. If you
do not have the Owner’s Manual, please contact
Nautilus, Inc. at 1-800-628-8458 for a replacement
copy.
2. Keep children away from this machine and /
or supervise them closely if they are near the
machine or present during its operation. This
machine is not suitable as a children’s toy. There
is a natural tendency for children to want to play
on exercise equipment and parents and other
in charge of children should be aware of their
respective responsibilities. Moving parts that may
appear to present obvious hazards to adults may
not appear to do so to children. Keep the Power
Rod®resistance rods bound when they are not in
use to immobilize the machine.
3. This machine is designed for a User’s Weight Limit
of 300 pounds (136 kg). Do not use if you are over
this weight.

Before You Assemble
Before You Assemble
Please take the time to read all assembly instructions
before attempting to assemble and install your
Bowflex®Gym Style Ab Crunch Station accessory.
Basic Assembly Principles
Here are a few basic tips that will make your assembly of the
Bowflex®Gym Style Ab Crunch Station quick and easy. 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 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 Bowflex®
Gym Style Ab Crunch Station, turn bolts or nuts toward the
right (clockwise) to tighten and left (counterclockwise) to
loosen. Or you can remember the mnemonic: “Righty tighty,
lefty loosey.”
