Pro-Form PETL70707.2 User Manual page 27

Locate the Reed Switch (71) and the Magnet (50)
on the left side of the Pulley (51). 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 neces-
sary, loosen the 3/4" Reed Switch Screw (15),
move the Reed Switch slightly, and then retighten
the Screw. Reattach the Hood (not shown), and run
the treadmill for a few minutes to check for a cor-
rect 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 23 to turn off the demo mode.
PROBLEM: The walking belt slows when walked on
SOLUTION: a. If an extension cord is needed, use only a 3-conductor, 14-gauge (1 mm
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
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 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 walking
belt is properly tightened.
c. If the walking belt still slows when walked on, see the front cover of this manual.
