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
on the machine, ready to exercise.
Basic Assembly Principals
Here are few basic assembly tips that can make assembly
of your Nautilus® Commercial Series Bike 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 Series Bike, 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. The tools needed to assemble your Nautilus®
Commercial Series Bike are provided. 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 Series Bike.
Select Your Workout Area
Select where you are going to put your Nautilus®
Commercial Series Bike carefully. The best place for
your exercise bike is on a hard, level surface. You will
need at least 18 inches (.45 meters) on each side of the
Commercial Series Bike and 18 inches (.45 meters) behind
your U916 for dismount.
Make sure that the location you choose has a grounded,
3-prong power outlet within reach of the Nautilus®
Commercial Series Bike power cord.
NOTE: The Nautilus® Commercial Series Bike is designed
to plug into a grounded, non-GFI outlets only. To determine
if your outlet or circuit breaker is GFI, look for a test and
reset button on them. If they have the test and reset
button it is a GFI outlet or circuit breaker.
Further, if you ever perform any repairs on your
Commercial Series Bike that require you to lay it on its
side, you will need at least five feet to one side of your
workout area.
Positioning Your Nautilus® Commercial Series Bike
Take great care when moving your Commercial Series Bike
into place prior to assembly.
To move the upright bike, stand in front of the machine and
grasp the handlebars. Pull down until the transport wheels
are in contact with the ground. (Note: Do not push down
on the plastic shroud with your feet when tilting machine up
to contact the transport wheels with the ground. Use the
stabilizer bars instead, to avoid any damage to the plastic
covers.) The machine can now be rolled on the transport
wheels.
Do not grasp or move the the machine by holding onto the
computer console.
Note:
The transport wheels are intended for indoor use only and
should never be rolled on concrete or asphalt surfaces.
