Weslo 21 user manual Symptom The walking belt slows when walked on

Remove the five indicated M4.2 x 19mm Washer Head Screws (9). Then, carefully remove the Motor Hood (56).

Locate the Reed Switch (42) and the Magnet (44) on the left side of the Pulley (46). 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 (7), 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 incline of the treadmill does not change correctly

a.With the key in the console, press one of the Incline buttons. While the incline is changing, re- move the key. After a few seconds, re-insert the key. The treadmill will automatically rise to the maximum incline level and then return to the mini- mum level. This will recalibrate the incline system.

SYMPTOM: The walking belt slows when walked on

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

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 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.

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 in- structed to do so by an authorized service rep- resentative. Such substances may deteriorate the walking belt and cause excessive wear. If you suspect 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.
