TENSIONING 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 might need to be adjusted after the first two hours of use. Temperature, 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 directions below.
1) Locate the two hex head bolts on the rear of the treadmill. The bolts are located at each end of the frame at the back
of the treadmill. These bolts adjust the rear belt roller. Do not adjust until the treadmill is on. This will prevent over
tightening of one side.
2) The belt should have equal distance on either side between the frame. If the belt is touching one side, do not start
the treadmill. Turn the bolts counter clockwise approximately one full turn on each side. Manually center the belt by
pushing the belt from side to side until it is parallel with the side rails. Tighten the bolts the same amount as when the
user loosened them, approximately one full turn. Inspect the belt for damage.
3) Start the treadmill running belt by pressing the GO buttion. Increase speed to 3 mph (~4.8 kph) and observe the belt
position. If it is moving to the right, tighten the right bolt by turning it clockwise ¼ turn, and loosen the left bolt ¼ turn. If
it is moving to the left, tighten the left bolt by turning it clockwise ¼ turn and loosen the right ¼ turn. Repeat Step 3 until
the belt remains centered for several minutes.
4) Check the tension of the belt. The belt should be very snug. When a person walks or runs on the belt, it should not
hesitate or slip. If this occurs, tighten the belt by turning both bolts clockwise ¼ turn. Repeat if necessary.
NOTE: Use the orange strip in the lateral position of the side rails as criteria to confirm the belt is properly centered. It is
necessary to adjust the belt until the edge of the belt is parallel to the orange or white strip.
CAUTION
Do not run belt faster than 3 mph (~4.8 kph) while centering. Keep fingers, hair and clothing away from belt at all times.
Treadmills equipped with side handrails and front handlebar for user support and emergency dismount, press
emergency button to stop the machine for emergency dismount.
