Make sure that the gap between the Magnet and the Reed Switch is about 1/8". If necessary, loosen the M4 x 19mm Screw (1), move the Reed Switch slightly, and then retighten the Screw. Reattach the Hood, and run the treadmill for a few minutes to check for a correct speed reading.

PROBLEM: The console displays remain lit when you remove the key from the console

SOLUTION: a. The console features a display demo mode, designed to be used if the treadmill is displayed in a store. If the displays remain lit when you remove the key, the demo mode is turned on. To turn off the demo mode, hold down the Stop button for a few seconds. If the displays are still lit, see THE INFORMATION MODE on page 16 to turn off the demo mode.

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 11.

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 2 to 3 inches 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.

c. If the walking belt still slows when walked on, see the back cover of this manual.

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 hex key to turn the left rear roller bolt clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the bolt counterclockwise 1/2 of a turn. Be careful not to overtighten the walking belt. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walk- ing belt is centered.

b. If the walking belt slips when walked on, first re- move the key and UNPLUG THE POWER CORD. Using the hex key, turn both rear roller bolts clock- wise, 1/4 of a turn. When the walking belt is cor- rectly tightened, you should be able to lift each side of the walking belt 2 to 3 inches off the walking plat- form. Be careful to keep the walking belt centered. Then, 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.
