Maintaining Your Treadmill
The M9.1 or M9.2s Precision Electronic Treadmill requires little maintenance to keep it running
smoothly and efficiently. However, the customer is responsible for the typical maintenance tasks
such as, cleaning the treadmill and adjusting the running belt. If you fail to maintain the treadmill
as described below, it could affect or void the Precor limited warranty.
Cleaning the Equipment
Your Precor treadmill relies on low friction for efficient operation. To keep the friction low, the
treadmill must be as clean as possible.
Before a workout, use a damp, soft, clean cloth to clean the side platforms and running bed, (refer
to the callouts in Diagram 15 on page 24). This removes any dirt or dust that might affect the
smooth operation of the treadmill.
Vacuum the floor underneath the unit every week to prevent the accumulation of dust and dirt on
the running belt.
To periodically clean the treadmill’s frame, electronic console, and running belt use a solution of
mild soap and water and dampen a clean cloth. To clean the running belt and the groves on the
plastic trim strip, use a soft nylon scrub brush. Never pour water or spray liquids on the electronic
console. Allow the treadmill to dry completely before using it.
Manually advance the running belt to clean the opposite side. Do not clean the belt while the
running belt is moving. Liquid can splash onto the motor causing damage to the equipment and
possibly injuring you.
Aligning the Running Belt
Before aligning the running belt, check its operation by following the procedure in
Checking the
Alignment of the Running Belt
earlier in this manual. If you determine that the belt needs adjust-
ment, 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
on page 25).
Follow the steps on the next page 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. See Diagram 15 on the next
page. 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 (H) 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
.
3. Place the magnetic safety key in the ACTIVATE position and turn ON ( I ) the treadmill, answer
the start-up prompts, then increase the running belt speed to 2 miles per hour by pressing the
SPEED key.
4. Observe the running belt for a couple of minutes. The belt should track centered on the
running bed.
CAUTION: Turn OFF the treadmill and
disconnect the power cable before performing
most maintenance tasks.
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 stopimmediately if an object becomes
caught in the belt or rollers.
