Checking the Alignment and Adjusting the Running Belt
Proper belt alignment allows the belt to remain centered and ensures smooth operation. Realigning the belt takes a few simple adjustments. If you are
unsure about this procedure, contact Precor Customer Support. Refer to Obtaining Service.
To check the alignment:
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 and 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.
1. Turn the unit On.
2. Stand beside the treadmill and press QUICKSTART.
3. If needed, enter the safety code by pressing the number key sequence:
1, 2, 3, 4.
The running belt starts automatically after a 3-second countdown
appears on the display.
4. Press the SPEED ▲ key until the display shows a speed of
3mph(5kph).
CAUTION: If you hear any chafing or the running belt appears
to be getting damaged, stop the running belt immediately by
pressing the red STOP button. Contact Precor Customer Support.
5. Walk around to the rear of the unit and observe the belt for a few
minutes. The belt should run centered along the running bed. If the belt
drifts off center, you must make adjustments. Refer to Adjusting the
Running Belt.
Important: If the belt needs alignment, make the adjustments at once.
Failure to align the belt may cause the belt to tear or fray, which is not
covered by the Precor Limited Warranty.
6. To stop the running belt, press the red STOP button.
7. Turn the treadmill Off.
To adjust the running belt:
If you are unsure about adjusting the running belt, contact Precor Customer
Support (refer to Obtaining Service).
CAUTION: For your safety, use the power switch to turn Off the
treadmill before making any adjustments. Do not adjust the running
belt when someone is standing on the unit.
1. Locate the right belt adjustment bolt in the rear end cap of the treadmill.
To determine left and right, stand at the rear of the treadmill and face
the display. Make all belt adjustments on the right rear corner bolt using
a ¼-inch hex key.
• If the belt is off center to the LEFT, turn the adjusting bolt ¼ turn
counterclockwise, which moves the running belt to the right.
• If the belt is off center to the RIGHT, turn the bolt ¼ turn clockwise,
which moves the belt to the left.
Important: Do not turn the adjusting bolt more than ¼ turn at a time.
Overtightening the bolt can damage the treadmill.
2. Recheck the alignment of the running belt.
