Precor 904 owner manual Adjusting the Elevation Tube

CAUTION: To avoid injury, the locking pins should be inserted and secured during these steps.

j.Securely tighten the T-knob by turning it clockwise. Alternately tighten the T-knobs until both are tight against the side rails.

5.Adjust the incline of the treadmill and set the running belt to the proper resistance level by following the steps in Adjusting the Elevation Tube.

Adjusting the Elevation Tube

The height of the elevation tube is adjusted at the factory. The height adjust- ment pin is placed at the middle setting (Setting #3—See Table 1). To receive optimal performance, you may need to reposition the height adjustment pin by taking the following steps:

1.Determine the proper Elevation Tube Setting. (Table 1) The elevation tube has six different settings. Each setting provides a different level of resistance needed (dependent on your weight) to maintain an efficient workout. To get optimal performance from your treadmill, refer to the settings shown in Table 1.

To determine if you have set the proper elevation for your height and weight, stand on the running belt with your hands on the handrails for balance. Your feet should slide slowly and easily away toward the rear of the treadmill. Begin walking. When you are comfortable and well-balanced on the treadmill, release your grip on the handrails. The running belt should continue to move freely while you maintain your momentum. If the running belt slows, stops, or becomes more difficult to walk on, consider increasing the incline of the treadmill by moving the elevation tube up one more setting.

Table 1 is an approximation and elevation tube settings may vary slightly depending on differences in weight and the amount of lubrication between the running belt and deck. Over time and extended use, you may need to readjust the elevation tube setting or add lubricant between the running belt and deck—this is normal and does not require a service call.

Remember that you want to be able to maintain your momentum on the running belt without having to push off from the handrails. A lubrication kit, available from an authorized Precor dealer, can be used as friction (between the running belt and deck) increases. If you do lubricate the deck, you may need to change the elevation settings. See Obtaining Service to learn how to contact the authorized Precor dealer nearest you.
