STEP 6
Adjust Walk Belt Tension
Walk belt tension is important to treadmill performance. As your foot hits the
walk belt, does the walk belt stop sluggishly before regaining traction? Or, if
you stomp your feet, bracing against the direction of rotation, does the walk
belt not pause whatsoever? When either of these two conditions occurs,
walk belt tension should be adjusted. To further examine walk belt tension,
lift both sides of the walk belt at the center of its length (Shown in figure A &
B). The walk belt should rise 30 mm (about 1 1/8th inch). A hanging gauge,
should measure the weight at 3 kg or 6.6 lb.
Adjust the tension if it differs from this specification. If the walk belt is too
loose, use a hex wrench to turn rear roller screws clockwise one quarter
rotation at a time. If the walk belt is too tight, use a hex wrench to turn rear
roller screws counterclockwise one half rotation at a time. Test walk belt ten-
sion after each adjustment and repeat the process until the tension is right.
Do not turn the screw more than 2 turns. Note: The gap between the finger
pinch guard and the rear roller should be 2mm. If it is larger than 6mm, then
remove the step rail and loosen the finger pinch guard to adjust its position
(Shown in figure C).
