ADJUSTING THE RUNNING BELT
After placing the treadmill in the position it will be used, the belt must be checked for proper tension and
centering. The belt may need to be adjusted after the first 2 hours of use. Temperature and humidity, and
use cause the belt to stretch at different rates. If the belt starts to slip when a user is on it, be sure to follow
the direction below.
Step1: Locate the two hex head bolt on the rear of the treadmill. The bolts are located at each end of the
frame at the back of treadmill. These bolts adjust the rear roller. Do not adjust until the treadmill is on. This
will prevent over tightening of one side.
Step2: The belt should have equal distance on either side between the frames. If the belt is touching one
side, do not start the treadmill. Turn the bolts counter clockwise approximately one full turn one each side.
Manually center the belt by pushing the belt from side to side. Tighten the bolts the same amount as when
the user loosened them, approximately one full turn. Inspect the belt for damage.
Step3: While the treadmill is running at 3 mph, observe the belt position. If it is moving to the right, tighten the
Right bolt by turning it clockwise 1/4 turns, and loosen the left bolt 1/4 turn. If it is moving to the left, tighten
the left tighten the left bolt by turning it clockwise 1/4 turn and loosen the right 1/4 turn. Repeat step 3 until
the belt remains centered for several minutes.
Step4: Check the tension of the belt. The belt should be very snug. When a person walks or run on the belt,
it should not hesitate or slip. If this occurs, tighten the belt by turning both bolts clockwise 1/4 turn, Repeat if
necessary.
