M9.3x Low-Impact Treadmills Assembly Guide 7
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, call Precor
Customer Support at 1-800-347-4404.
To check the alignment:
1. The treadmill has adjustable rear feet. Make sure that the running
surface is level. If the treadmill is placed on an uneven surface,
adjusting the rear feet can help, but will not compensate for
extremely uneven surfaces.
Important: Do not raise or lower the unit beyond 2 centimeters
(¾ inch). Check the level of the unit after each adjustment.
2. Turn the unit ON.
3. Stand beside the treadmill and press QUICKSTART.
4. If you are prompted for a password, press
INCLINE▼, SPEED ▼, SPEED ▲. The running belt starts
automatically after the 3-second countdown appears on the
display.
5. Press the SPEED s key until the display shows a speed of 3 mph
(5 kph).
6. 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 will need to make adjustments.
Important: If the belt needs alignment, make the adjustments
immediately after turning the treadmill OFF. Failure to do so may
cause the belt to tear or fray, which is not covered by the Precor
Limited Warranty.
7. To stop the running belt, press the red STOP button.
8. Turn the treadmill OFF.
To adjust the running belt:
CAUTION: To ensure your safety, turn OFF (O) the treadmill
before making any adjustments.
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 the 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 tracks off center to the
RIGHT, turn the bolt ¼ turn
clockwise; this 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.
