bracket. Using a measuring tape, measure the distance from the front of the left side drive roller
shaft to the front of the frame cross beam and make note of that measurement. Tighten the right
side drive roller bolt until it measures the same distance as the left side drive roller, shaft to frame.
This will ensure that the drive roller is parallel and square to the front of the frame.
10.
Walk the drive belt onto the drive roller pulley by rotating the drive motor flywheel. Be sure the belt
is fully seated in the grooves of both pulleys and correctly aligned. A drive belt tension gauge
should read 100-120 pounds. The drive belt de-tension after use. A range of 80-90 pounds after
the belt has been installed for a while is acceptable.
11.
Move the running belt so that the seam is underneath the treadmill. Place a running belt tension
gauge on each side of the running belt parallel from each other. The gauges have a fixed side and a
movable side. Place the movable side to the middle of its travel and adjust the dial pointer to the
number 3.
NOTE: Using the number 3 as a reference point and centering the movable side of the gauge allows
increment or decrement movement without impeding the travel of the gauge.
12.
Carefully move the running belt so that you can see the dials easily while tightening the take up
roller mounting bolts. Tighten the take up roller mounting bolts alternately in order to evenly
tighten the running belt. Tighten bolts until the gauges read .55%, which is five and 1/2 lines past
the number 3.
