Adjusting the Resistance Level

The micro-adjustment knob on the 903 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 903 treadmill—Assembly Instructions

•adjusted the elevation tube settings—Adjusting the Elevation Tube

•checked the running belt alignment—Aligning the Running Belt

CAUTION: Avoid excessive wear to the running belt by setting the proper elevation for your weight. Refer to Table 1 on page 7.

Diagram 6 shows the location of the micro-adjustment knobs on the 903 treadmill.

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

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 re-adjust the elevation and resistance according to his or her needs. Refer to Table 1 on page 7 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.

•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 hold onto the handrail to push against the running belt to keep it moving, you will need to adjust the elevation tube setting up to the next hole. Refer to Adjusting the Elevation Tube.
