5. Walk around to the rear of the unit and observe the belt
for a few minutes. The belt should be centered on the
platform. If the belt drifts off center, you must make
adjustments.
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 STOP key.
7. Turn the treadmill OFF.
Adjusting the Running Belt
If you are unsure about adjusting the running belt, call
Precor Customer Support (see Obtaining Service).
CAUTION: Always use the I/O power switch to turn
OFF the treadmill before making any adjustments. Do
not adjust the running belt when someone is standing
on the unit.
1. Locate the right belt adjustment bolt in the rear end cap
of the treadmill. Refer to Diagram 12.
Diagram 12: Adjusting belt location
To determine left and right, stand at the rear of the
treadmill and face the display.) Make all belt adjustments
on the right rear corner bolt using the hex key provided.
If the belt is off center to the LEFT, turn the adjusting
bolt ¼ turn counterclockwise, which moves the
running belt to the right.
If the belt tracks off center to the RIGHT, turn the bolt
¼ turn clockwise; this moves the belt to the left.
Important: Do not turn the adjusting bolt more than
¼ turn at a time. Overtightening the bolt can damage
the treadmill.
2. Recheck the alignment of the running belt.
