CAUTION: Avoid excessive wear to the running belt by setting the proper elevation for your weight. Refer to Table 1 on page 13.

Using the Micro-Adjustment Knob

The micro-adjustment knob on the 904 treadmill allows adjustments that affect the movement of the running belt. Adjust the resistance while you are walking or running on the treadmill. Before using the micro-adjustment knob, make sure that you have completed the following procedures:

•assembled your 904 treadmill—Assembly Instructions

•adjusted the elevation tube settings—Adjusting the Elevation Tube

•checked the running belt alignment—Aligning the Running Belt

•determined handrail usage—Using the Handrails

Diagram 13 on page 17 shows the location of the micro-adjustment knob on the 904 treadmill.

Note: Remember that the running belt should move freely while you maintain a comfortable momentum (without holding onto the handrails).

If more than one person in your household uses the treadmill, be sure to release the belt resistance at the end of your workout by turning the micro- adjustment knob clockwise till it stops. This allows the next person on the treadmill to properly readjust the elevation and resistance according to his or her needs. Refer to Table 1 on page 13 to set the treadmill to the proper elevation before beginning a workout.

•To increase the resistance of the running belt and decrease speed, slowly turn the knob counterclockwise. The micro-adjustment knob is a fine- tuning device. Screw threads appear if the micro-adjustment knob is rotated too many times. If you see the threads beginning to appear, turn the knob clockwise till it stops, step off the treadmill, and readjust its incline. Refer to Adjusting the Elevation Tube.

•To reduce the resistance of the running belt and increase speed, slowly turn the knob clockwise.

Important: If the micro-adjustment knob is turned clockwise as far as it can go and you need to continually push against the handrails to keep the running belt moving, you will need to raise the elevation and reset the height adjustment pins into the next hole. Refer to Adjusting the Elevation Tube.
