Belt and Bed - Your treadmill uses a very high-efficient low-friction bed. Performance is
maximized when the bed is kept as clean as possible. Use a soft, damp cloth, or paper towel,
wipe the edge of the belt and the area between the belt edge and the frame. Also reach as far as
practical directly under the belt edge. This should be done once a month to extend belt and bed
life. A mild soap and water solution along with a nylon scrub brush will clean the top of the
textured belt. Allow to dry before using.
Belt Dust - This occurs during normal break-in or until the belt stabilizes. Sometimes the black
dust from the belt will appear on the floor behind the treadmill, this is normal.
General Cleaning - Dirt, dust, and pet hair can block air inlets and accumulate on the running
belt. Please vacuum underneath your treadmill on a monthly basis to prevent excess build-up of
dirt that can get sucked up and get into the inner workings under the motor cover. Once a year,
you should remove the black motor hood and vacuum out dirt that may accumulate. UNPLUG
POWER CORD BEFORE THIS TASK.
BELT ADJUSTMENTS:
Tread-belt Tension Adjustment - Belt tension is not critical for most users. It is very important
though for joggers and runners in order to provide a smooth, steady running surface. Adjustment
must be made from the rear roller with the 6 mm Allen wrench provided in the parts package. The
adjustment bolts are located at the end of the step rails as shown in the diagram below.
Tighten the rear roller only enough to prevent slippage at the front roller. Turn the tread-belt
tension adjusting bolts 1/4 turn each and inspect for proper tension by walking on the belt and
making sure it is not slipping or hesitating with each step. When an adjustment is made to the
belt tension, you must be sure to turn the bolts on both sides evenly or the belt could start
tracking to one side instead of running in the middle of the deck.
DO NOT OVERTIGHTEN – Over tightening will cause belt damage and premature bearing
failure. If you tighten the belt a lot and it still slips, the problem could actually be the drive belt -
located under the motor cover - that connects the motor to the front roller. If that belt is loose it
feels similar to the walking belt being loose. Tightening the motor belt should be done by a
trained service person.
Note: Adjustment is through small hole in end cap.
