Locate the Reed Switch (24) and the Magnet (18) on
the left side of the Pulley (120). 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”.

If necessary, loosen the

Screw (25), move the Reed Switch slightly, and then
retighten the Screw. Then, reattach the hood (not
shown), making sure that each screw is in the hole
from which it was removed. Run on the treadmill for a
few minutes to check for a correct speed reading.

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
permanently damaged. Remove the key and 

UN-

PLUG THE POWER CORD

. Using the included allen

wrench, turn both rear roller bolts counterclockwise
1/4 of a turn. When the walking belt is properly tight-
ened, you should be able to lift each edge of the
walking belt 3 to 4 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 tread-
mill for a few minutes. Repeat until the walking belt is
properly tightened.

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

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
