PROBLEM: The walking belt is off-center or slips when walked on

SOLUTION: a. If the walking belt has shifted to the left, first re- move the key and UNPLUG THE POWER CORD. Using the allen wrench, turn the left rear roller adjust- ment bolt clockwise, and the right bolt counterclock- wise, 1/4 of a turn each. Be careful not to overtighten the walking belt. Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is centered.

b. If the walking belt has shifted to the right, first re- move the key and UNPLUG THE POWER CORD. Using the allen wrench, turn the left rear roller adjust- ment bolt counterclockwise, and the right bolt clock- wise, 1/4 of a turn each. Be careful not to overtighten the walking belt. Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is centered.

c. If the walking belt slips when walked on, first re- move the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjust- ment bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off 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.

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. 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.
