Belt Tracking Adjustments
When to Adjust
The treadmill walking-belt tension is set at the factory. However, you
should test the belt tracking every time the treadmill is moved. Run the
treadmill for several minutes with no one exercising. If the belt tracks to
one side or the other, then you must adjust the belt tracking.
It is not unusual for the treadmill belt to move slightly off center while a
person with a heavy gait is exercising. A properly adjusted belt recenters
itself when the person steps off the treadmill. If the belt does not
recenter, check the treadmill level and adjust the belt tracking as
described.
Check Treadmill Level
1. Use the controlling equipment to set the treadmill elevation to
0.0%.
2. Check the treadmill level with a carpenter’s level.
3. If the treadmill is uneven, adjust the feet at the rear of the
treadmill until it is stable.
For stability, use one shim of the right thickness (rather than
several thin shims) to achieve the proper level.
If necessary, use longer shims to accommodate the maximum
treadmill elevation. The treadmill wheels must not roll off the
shims. Verify that the shim lengths exceed the wheel movement
when the treadmill is fully elevated.
4. If you cannot level the treadmill safely with shims, move the
treadmill to another location.
WARNING
Keep hands, hair,
jewelry, and loose
clothing away from
moving parts.
