5.SYMPTOM: The walking belt slows when walked on

a. Use only a UL-listed surge protector, rated at 15 amps, with a 14-gauge cord of five feet or less in length.

b. If the walking belt is overtightened, treadmill performance may decrease and the walking belt may be permanently damaged. Remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjustment bolts counterclock- wise, 1/4 of a turn.

Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is prop- erly tightened.
