Checking the Alignment of the Running Belt
Before working out on your treadmill, you need to check the alignment of the running belt. The running belt on the 903 treadmill has been fully adjusted at the factory and should track straight on the deck. However, if the running belt seems to track off center of the deck or you hear a chafing noise, check the belt alignment by taking the following steps:
1.Walk on the treadmill while holding onto the handrail for balance.
2.Observe the running belt for a couple minutes.
3.If the running belt tracks off center or the belt moves toward either flywheel, you need to align the belt.
4.If you determine that the belt needs alignment, follow the steps in Aligning the Running Belt found in the maintenance section of this manual.
Once the treadmill is assembled, be sure to check the alignment of the belt periodically. Adjust the running belt as soon as it needs alignment to prevent tearing or fraying of the belt. Any damage due to improper maintenance of the running belt is not covered by the limited warranty.
