HOW TO ADJUST THE CUSHIONING SYSTEM
The treadmill features a cushioning system that re-
duces the impact as you walk or run on the treadmill.
To increase the firmness of the walking platform, step
off the treadmill and slide the cushion adjusters toward
the front of the treadmill. To decrease the firmness,
slide the cushion adjusters toward the back of the
treadmill. Note: Make sure that both adjusters are
set at the same firmness level. The faster you run
on the treadmill, or the more you weigh, the firmer
the walking platform should be.
