PROBLEM: The walking belt slows when walked on

SOLUTION: a. Use only a single-outlet surge suppressor that is UL 1449 listed as a transient voltage surge sup- pressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules. The surge suppressor must be electrically rated for 120 volts AC and 15 amps.

b. If the walking belt is overtightened, treadmill perfor- mance may decrease and the walking belt may be permanently damaged. Remove the key and UN- PLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjustment bolts counterclock- wise, 1/4 of a turn. When the walking belt is properly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. The center of the walking belt should just touch the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened.
