Figure 4-1. Treadbelt Tensioning Bolts (one per side)
4.3.3. Treadbelt Tensioning
The treadbelt is tensioned at the factory but may require
adjustment after installation. Need for tensioning is indicated by
uneven belt speed and may be felt as sudden stopping of the
treadbelt when your foot comes down on the belt.
Before checking treadbelt tension, make sure treadmill is level.
(See “Leveling the Treadmill” on page 33.) At proper tension
you should be able to place your hand between the belt and
deck and reach the center of the treadmill Figure 4-2. .
•
If you cannot reach the center, the belt is too tight.
•
If you can reach past the center, the belt is too loose.
Figure 4-2. Treadbelt Tension Check
To check belt tension: run treadmill at 1 mph, then walk on it. If
the belt does not feel like it is slipping or hesitating, then the
belt is tensioned correctly. If the belt slips/hesitates, then it is
not fully tensioned.
