PROBLEM: The walking belt slows when walked on
SOLUTION: a. If an extension cord is needed, use only a 3-conductor, 1mm
than 1.5 m (5 ft.).
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
adjustment bolts counterclockwise, 1/4 of a turn. When
the walking belt is properly tightened, you should be
able to lift each side of the walking belt 5 to 7 cm (2–3
in.) off the walking platform. Be careful to keep the
walking belt centred. 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, please call our Customer Service Department.
PROBLEM: The walking belt is off-centre or slips when walked on
SOLUTION: a. If the walking belt is off-centre, 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 rear roller bolt clockwise 1/2 of a turn; if the
walking belt has shifted to the right, turn the bolt
counterclockwise 1/2 of a turn. Be careful not to over-
tighten 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 centred.
b. If the walking belt slips when walked on, first re-
move the key and UNPLUG THE POWER CORD.
Using the hex key, turn both rear roller bolts clock-
wise, 1/4 of a turn. When the walking belt is correctly
tightened, you should be able to lift each side of the
walking belt 5 to 7 cm (2–3 in.) off the walking plat-
form. Be careful to keep the walking belt centred. Plug
in the power cord, insert the key, and carefully walk
on the treadmill for a few minutes. Repeat until the
walking belt is properly tightened.
PROBLEM: The incline of the treadmill does not change correctly
SOLUTION: a. With the key in the console, press one of the Incline buttons. Whilst 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 minimum level. This will recalibrate the incline system.

2. With the help of a second person, carefully tip the
Upright Base (97) down as shown. (Note: It may be help-
ful to place your foot on one of the Extension Legs [92]
as you tip the Upright Base.) Make sure that the
Extension Legs remain in the Upright Base.
Attach each Extension Leg (92) with two Extension Leg
Bolts (96) and two 1/4" Washers (39) as shown. Thread
a Levelling Foot (95) into each side of the Upright Base
(97); do not thread the Levelling Feet fully into the
Upright Base.
Attach the two Base Pads (99) to the Upright Base (97)
in the locations shown with two 1" Tek Screws (135).
With the help of a second person, raise the Upright Base
(97) to the vertical position.
3. Attach the Latch Assembly (82) to the Left Upright (84)
with the two Latch Screws (134). Start both Latch Screws
before tightening either of them. Note: The Latch Screws
may be preattached to the Left Upright.
4. See step 6 and locate the four Upright Bolts (86). Loosen
the Upright Bolts two to three turns.
See drawing 4c. With the help of a second person, hold
the Console Base (101) near the Uprights (80, 84). Look
under the Console Base and locate the wires on the
sides of the Console Base. Make sure that the wires are
not routed through the openings for the Trays (109,
111). Drawing 4a shows the correct route for the wires.
Drawing 4b shows an incorrect route.
See drawing 4c. Cut the plastic ties holding the Wire
Harness (74) and the Pulse Wire (153) in the Uprights
(80, 84). Connect the Wire Harness and the Pulse Wire
to the wires on the sides of the Console Base (101).
Make sure to connect the connectors properly (see
the inset drawings). IF THE CONNECTORS ARE NOT
CONNECTED PROPERLY, THE CONSOLE MAY BE
DAMAGED WHEN THE POWER IS TURNED ON. The
connectors should slide together easily and snap
into place. If the connectors do not slide together easily
and snap into place, turn one connector and try again.
Insert the excess Wire Harness and Pulse Wire up into
the Console Base.
