Symptom The walking belt slows when walked on

Locate the Reed Switch (89) and the Magnet (62) on the left side of the Pulley (71). Turn the Pulley until the Magnet is aligned with the Reed Switch.

Make sure that the gap between the Magnet and the Reed Switch is about 1/8 in. (3 mm). If necessary, loosen the M4.2 x 13mm Tek Screw (3), move the Reed Switch slightly, and then retighten the Screw. Reattach the Motor Hood (not shown), and run the treadmill for a few minutes to check for a correct speed reading.

SYMPTOM: The walking belt slows when walked on

a.Use only a surge suppressor that meets all of the specifications described on page 11.

b.If the walking belt is overtightened, treadmill per- formance may decrease and the walking belt may become damaged. Remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both idler roller screws 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 in. (5 to 7 cm) 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 walk- ing belt is properly tightened.

2–3 in.

Idler Roller Screws

c.Your treadmill features a walking belt coated with high-performance lubricant. IMPORTANT: Never apply silicone spray or other substances to the walking belt or the walking platform unless instructed to do so by an authorized service representative. Such substances may deterio- rate the walking belt and cause excessive wear. If you suspect that the walking belt needs more lubricant, see the front cover of this manual.

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

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

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 idler roller screw clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the left idler roller screw counterclock- wise 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 walking belt is centered.
