PROBLEM: The walking belt slows when walked on

SOLUTION: a. Use only a single-outlet surge suppressor that meets all of the specifications described on page 10.

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 allen wrench, turn both rear roller adjustment bolts counterclockwise, 1/4 of a turn. When the walking belt is properly tightened, you should be able to lift each side of the walking belt 2 to 3 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, in- sert the key, and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened.

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

SOLUTION: a. If the walking belt is off-center, first remove the key and UNPLUG THE POWER CORD. If the walking belt has shifted to the left, use the allen wrench to turn the left rear roller bolt clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the left bolt counterclockwise 1/2 of a turn. 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 allen wrench, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tight- ened, you should be able to lift each side of the walk- ing belt 2 to 3 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.

PROBLEM: One of the upper body arms squeaks during use

SOLUTION: a. Correcting this problem requires a small amount of white marine grease, available at most hardware stores. Turn the Resistance Knob (109) counterclock- wise until it can be removed. Remove the Resistance Cone (108) and the Upper Body Arm (117), along with the 3/8” Washers (5), Spring Washer (111), Thrust Washers (112), and Thrust Bearing (113). (Note: If the Resistance Sleeve [107] or Resistance Plate [27] comes out of the Resistance Bracket [105] or Resistance Cone, press it back in.) Apply a thin layer of white marine grease to the outer surface of the Resistance Cone (108). Reattach all parts in the order shown at the right.
