CHAPTER 3: PREVENTATIVE MAINTENANCE

3.6 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,
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.
STEP 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 roller. Do not adjust until the
treadmill is on. This will prevent over tightening of one side.
STEP 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. Tighten the bolts the same amount as when the
user loosened them, approximately one full turn. Inspect the belt
for damage.
STEP 3: 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 turn, and loosen the left bolt 1/4 turn. If it is moving
to 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.
STEP 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 1/4 turn. Repeat if necessary.
