   Locate the Reed Switch (52) and the Magnet (50) 
on the left side of the Pulley (49). 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 #8 x 3/4" Tek Screw (14), 
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, 
remove the key. After a few seconds, reinsert 
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.    Use only a single-outlet surge suppressor that 
meets all of the specications described on page 
15.
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.
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.
