PROBLEM: The walking belt slows when walked on

SOLUTION: a. If an extension cord is needed, use only a 3-conductor, 1mm2 (14-gauge) cord that is no longer than 1.5 m (5 ft.).

b.If the walking belt is overtightened, treadmill perfor- mance may decrease and the walking belt may be- come damaged. Remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both rear roller bolts counterclockwise, 1/4 of a turn. When the walking belt is properly tightened, you should be able to lift each edge of the walking belt 5 to 7 cm (2 to 3 in.) off the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened.

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 slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each edge of the walking belt 5 to 7 cm (2 to 3 in.) off the walking platform. Be careful to keep the walking belt centered.
