HOW TO ADJUST THE CUSHIONING SYSTEM The treadmill features a cushioning system that reduces the impact as you walk or run on the treadmill. Remove the key from the console and unplug the power cord. To adjust the cushions, you may need to place the treadmill in the storage position (see HOW TO FOLD THE TREADMILL on page 28). For more rmness, turn a cushion to the position shown in drawing 1; for less rmness, turn the cushion to the position shown in drawing 2. Adjust the other cushions in the same way. Note: Make sure that the cushions on the left and right sides of the treadmill are set to the same firmness level. The faster you run on the treadmill, or the more you weigh, the firmer the walking platform should be. 1 More firm 2 Less firm 27
