2.

Remove the old battery and replace it with a fresh one. Make sure that the positive (+) side
is up facing you.

3.

Screw the battery cover back into place.

4.

Test the battery by putting on the chest strap as described in 

Wearing the Chest Strap

Transmitter. Stand within 3 feet and face the electronic console. (Be sure that the treadmill is
turned ON). If the battery has been installed properly, your heart rate should appear on the
display when you begin a workout program.

Storing the Chest Strap

Store the chest strap transmitter in a place where dust and dirt cannot accumulate on it such as, a
closet or drawer. Be sure to keep the chest strap protected from extremes in temperature. Do not
store it in an area that may be exposed to temperatures below 32 degrees Fahrenheit.

Aligning the Running Belt

Before aligning the running belt, check its operation by following the procedure in 

Checking the

Alignment of the Running Belt on page 14. If you determine that the belt needs alignment, follow
the instructions here.

Realigning the belt takes a few simple adjustments. If you are unsure about this procedure, call
your authorized Precor dealer for service (see 

Obtaining Service).

Take the following steps to adjust the running belt on the treadmill. To ensure your safety, make all
adjustments while the treadmill is OFF.

1.

Make sure the treadmill is OFF and the running belt has completely stopped.

2.

Locate the left belt adjustment bolt at the rear of the treadmill as shown in Diagram 17. The
direction you turn the bolt depends on how the belt is tracking. Make all belt adjustments on
the left rear corner bolt using the hex key provided.

If the belt is off center to the LEFT, turn the adjusting bolt 1/4 turn clockwise, which
moves the running belt to the right.

If the belt tracks off center to the RIGHT, turn the bolt 1/4 turn 

counterclockwise; this

moves the belt to the left.

Important: Do not turn the adjusting bolt more than 1/4 turn at a time. 

Overtightening the bolt

can damage the treadmill.

CAUTION: Special care must be taken when
aligning the running belt. Turn OFF the treadmill
while adjusting or working near the rear roller.
Remove any loose clothing and tie back your
hair. Be very careful to keep your fingers or any
other object clear of the belt and rollers,
especially in front of the roller and behind the
deck. The treadmill will not stop immediately if
an object becomes caught in the belt or rollers.
