Checking The Alignment; Adjusting The Running Belt - Precor TRM 425 Owner's Manual

Checking the Alignment

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. Refer to Obtaining Service.
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.
To check the alignment:
1. The treadmill has adjustable rear feet. Make sure that the running surface is
level before aligning or adjusting the running belt. For more information, see
Leveling the Treadmill.
2. Connect the power plug to an appropriate dedicated circuit and turn the unit
On.
3. Stand beside the treadmill and press QUICKSTART.
Note: If needed, enter the password. Refer to your owner's manual. The
running belt starts automatically after a 3-second countdown appears on the
display.
4. Increase the treadmill belt speed until the display shows a speed of 3 mph (5
kph).
CAUTION: If you hear any chafing or see that 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 will need to make adjustments. Refer to the next section.
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.
