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.
