mounting hardware in groups, in the order in which you
remove them. This simplifies reinstallation later.

To remove the access covers:

1. Using a rubber mallet or the heel of your hand, tap at an
upward angle against the side of the top column cover to
snap it loose.

Figure 6: Where to place pressure when removing top cover

2. Lift the cover, then slide it toward the rear of the
equipment and out.

3. Using a ⁵₃₂” hex wrench, disconnect the two 1-inch
buttonhead screws at the bottom of the front cover, then
snap the cover loose.

Threading the Cables

Depending on the model of console you are installing and the
options it includes, you will need to install one or more of the
following cables:

 Television (coaxial with F connectors)
 Power
 Ethernet

Precor recommends threading new cables from the top down,
to take advantage of gravity. A fish tape (a thin metal strip
with a hook or clasp on one end, available from professional
hardware vendors) can be helpful during this procedure.

Assembling the AMT 23

To thread new cables through the equipment:

1. Select the console power cable (red and black, individual
leads), the Ethernet cable (flat and black), or the
television cable (round and black).

2. Thread the cable through the center column at the front
of the equipment.

3. Guide the end of the cable through the gap at the bottom
of the center column, then attach it to the appropriate
connector on the jack panel. Refer to the following
illustration and table for the position of each connector.

Connect … To …

The console power
cable

The Ethernet cable The eight-connector modular jack on the

The television cable The coaxial connector on the jack panel

The power cable assembly

jack panel

4. Repeat steps 1 through 3 until all three cables are
completely installed.

5. Insert all cables into the cable clips on the center frame
pillar just below the bottom of the center column. Use
plastic ties to bind the cables together below the clips and
to route them away from any moving parts.

24 Assembling and Maintaining Adaptive Motion Trainers: AMT 885 /835

Replacing Access Covers

After you install the console cables, you can return the access
covers to their previous positions on the equipment.

To replace the access covers:

1. Snap the front cover back into place. Reinsert the two
buttonhead screws you removed with the front cover,
then tighten them using a ⁵₃₂” hex wrench.

2. Position the top column cover between the handlebars
and the body of the AMT. Make sure that the sides of the
top column cover extend over the upper edges of the
body covers, then use the heel of your hand or a rubber
mallet to tap the cover back into place.

Leveling the AMT

It is important that you level and stabilize the AMT properly
every time you move it.

CAUTION: To eliminate movement, make sure the adjustable feet
are in contact with the floor. Also, make sure that the unit sits on
a flat surface. Adjusting the feet of the unit cannot compensate
for extremely uneven surfaces.

To level the AMT:

1. Gently rock the AMT while standing on one of its foot
plates and grabbing the opposite handlebar. First stand on
the left foot plate and grab the right handlebar to rock the
AMT, then repeat the step while standing on the right
foot plate and holding the left handlebar. If there is any
movement, ask your assistant to tip the unit on its side
while you locate the adjustable feet.

Breaking in the Equipment

Precor equipment does not require an actual break-in period.
However, moving components such as belts, gears, and
bearings can settle while the equipment is being stored or
shipped. This can cause the equipment to operate with a
small amount of roughness or noise when it starts up for the
first time.

The equipment usually returns to smooth operation after a
day or two of normal use. If it does not, contact your dealer
for assistance. For more information, refer to Obtaining
Service.

Installing the Console

To make installation easier, all Precor Experience Series
consoles use the same mounting hardware and connector
locations whenever possible. The installation sequence for
any of them is as follows:

 Threading the cable assembly
 Connecting cables
 Completing the installation (tightening the mounting

screws and attaching the back cover)

The following sections describe how to perform these tasks.

Chapter 2

Threading the Cable Assembly (P80)

Earlier in the installation, you threaded the necessary cables
through the frame of the base unit and out the passthrough
opening in the console mount. As you line up the back plate
on the console with the console mount, you must make sure
that the cable assembly passes correctly through the
openings in both components.

28 Assembling and Maintaining Adaptive Motion Trainers: AMT 885 /835

Important: Before you begin the following procedure, remove the
rear cover from the control console. To remove the cover, use your
fingernails to pry the lower edge loose, then swing the cover up
and out as shown in the following illustration.

Figure 9: Removing the access cover from the P80 console

To thread the cable assembly:

1. Make sure that as much of each cable as possible passes
through the opening in the middle of the console mount
on the base unit.

2. Position the console over the console mount.

3. Rest the console on the console mount so that the notch
on the bottom of the console’s back plate rests on the
rectangular hook at the bottom of the console mount, as
shown in the following figure.

Figure 10: Console positioning on base unit

4. Tilt the console forward until it stops. Use one hand to
steady the console in this position, or ask your assistant
to do so.
