SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

1.2 SETUP
Read the entire Operation Manual before setting up the the treadmill.
FOLDING, MOVING, AND POSITIONING THE TREADMILL
The treadmill can be folded easily by means of a “gas shock” mechanism. Folding the treadmill when it is not in use
frees up floor space and makes it easy to move the unit.
Folding the treadmill: When the treadmill is idle, set the incline grade to 0 percent, switch the unit off, and unplug it.
Then, with both hands, lift the back end of the treadmill upward until it clicks and locks into place.
Caution: The treadmill must be set to 0% before folding. Damage may occur and the treadmill may
not lock into a proper upright position.
Moving and positioning the treadmill: Once the treadmill is folded and locked, simply roll it to the desired location.
When positioning the treadmill for use, allow for a clearance area of six feet by four feet behind the treadmill to make
it easy to get on and off the treadmill and to adjust the tension of the belt. See the section titled Specifications for the
treadmill’s dimensions. Also, make sure to use the treadmill on a firm, level surface.
Note: Occasionally, after extended treadmill use, a fine black dust may accumulate on the floor beneath the unit. This
does not indicate that anything is wrong with the treadmill, and the dust can easily be
removed with a vacuum cleaner. To prevent the dust from accumulating on floor, place a mat beneath the unit.
Unfolding the treadmill: Stand directly behind the treadmill. Support the treadmill base
with the right hand, and pull and hold the release handle downward with the left hand.
The handle is located on the end of the left main frame. Begin lowering the base a
short distance. Let go of the release handle and, with both hands, guide the treadmill
deck down to unfold it.
Caution: As the treadmill comes closer to the ground, it lowers at a faster rate and feels heavier.
ELECTRICAL REQUIREMENT
Consult the chart below for electrical requirements outside the U.S. and Canada. The plug must be inserted into an
electrical outlet that has been properly installed and grounded in accordance with all local codes and ordinances.
GROUNDING INSTRUCTIONS
This product must be properly grounded. If the unit malfunctions or breaks down, proper grounding provides a path of
least resistance for the electric current, which reduces the risk of shock to anyone touching or using the equipment.
Each unit is equipped with an electrical cord, which includes an equipment grounding conductor and a grounding
plug. The plug must be inserted into an outlet that has been properly installed and grounded in accordance with all
local codes and ordinances. Use only the power cord provided with this treadmill.
DANGER: A risk of electrical shock may result from improper connection of the equipment-grounding conductor.
Check with a qualified electrician if in doubt as to proper grounding technique. DO NOT modify the plug provided with
the product. If it will not fit an electrical outlet, have a proper outlet installed by a qualified electrician.
STARTING UP THE TREADMILL
The On/Off switch for the treadmill is located next to the power supply cord at the front of the treadmill. To start up
the treadmill, simply flip the switch to the On position (|).
The treadmill will start up only when the safety key has been properly inserted into the key-holder in the console. For
more information, see section 2.3, titled Emergency Stop System.

GETTING ON AND OFF THE TREADMILL
With the treadmill belt idle, step on the side rails to straddle the belt. Set up a workout using the steps described in
Section 4.2, titled Using the Workouts. When the belt is in motion, hold the handrails and carefully step onto the belt.
Continue to use the handrails as necessary for stability. After completing a workout, wait until the belt is idle before
stepping off.
CAUTION: Always face forward during a workout.
KEEPING THE TREADMILL DECK LUBRICATED
The treadmill deck has been pre-lubricated at the factory. However, it may require periodic lubrication throughout its
usage life for optimal performance and reduced wear-and-tear on important components . With an average rate of
use, which is approximately three weekly 30-minute workout sessions, the treadmill lubrication level should be
checked every 9 - 12 months.
To check the lubrication level: When the treadmill is idle, reach underneath the belt, palm-side-down, as far toward
the center as possible. Then, place the hand on the deck. If it is moist then it does not require lubrication. If the deck
is dry, it requires lubrication.
To add lubricant: The Lube-N-Walk®Wax Kit is recommended for this treadmill. Follow the instructions included
with the kit to add lubricant. Use of other lubrication kits may void the warranty. Contact the product service center for
more information on the Lube-N-Walk Wax Kit. See Section 5.3 for contact information.
CENTERING THE TREADMILL BELT
With normal use, the treadmill belt periodically may tend to run off-center. To test and adjust the belt, run the treadmill
at 4 mph (6.5 kph) without a user on it. To perform any centering adjustment, use the Allen wrench that was shipped
with the unit, and turn the left and right roller bolts, as described below. The roller bolts are located in the back of the
frame side rail.
If the belt runs too far to the left: Turn the left roller bolt one quarter-turn clockwise to tighten it. Then, turn the right
roller bolt on quarter-turn counterclockwise to loosen it.
If the belt runs too far to the right: Turn the right roller bolt one quarter-turn clockwise to tighten it. Then, turn the
left roller bolt on quarter-turn counterclockwise to loosen it.
After performing any adjustment, continue to run the belt without a user on it for three minutes to confirm that it is
centered. Repeat adjustments as necessary.
CAUTION: Never turn the bolts more than one quarter-turn at any time. Also, over-tightening the belt
can shorten the belt’s life considerably.
ADJUSTING THE TREADMILL BELT TENSION
As the belt stretches over time with normal use, the user may begin to feel the belt slipping across the rollers. The
slipping sensation indicates that the belt requires tightening. When the belt is idle and not in use, turn each roller bolt
one quarter turn clockwise to tighten it. Make sure to turn each bolt an equal amount.
Afterward, walk on the belt while it is in motion to test the adjustment. Repeat the tightening if necessary, but do not
turn the bolts more than one quarter-turn at any time.
If this adjustment does not stop the belt from slipping, call Customer Service. See section 5.3, titled How to Obtain
Product Service.
