Adjusting the Elevation Tube The elevation tube is set at the factory at the lowest setting. To receive optimal performance, reposition the height adjustment pin by taking the following steps: 1. Determine the proper Elevation Tube setting. (Table 1) The elevation tube provides 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 settings shown in Table 1.

Position the Treadmill on Its Side. (Diagram 4) Place your hands on either side of the handrail and gently tip the treadmill onto its side opposite the micro-adjustment knob. See Diagram 4.
Checking the Alignment of the Running Belt Before working out on your treadmill, you need to check the alignment of the running belt. The running belt on the 903 treadmill has been fully adjusted at the factory and should track straight on the deck. However, if the running belt seems to track off center of the deck or you hear a chafing noise, check the belt alignment by taking the following steps: 1. Walk on the treadmill while holding onto the handrail for balance. 2.
Using the Precor 903 Manual Treadmill In addition to providing an excellent cardiovascular workout, one of the advantages of the 903 Manual Treadmill is that it is simple to use. With very little time or practice, you can learn how to use it effectively.

Once you locate your pulse, look at the time and count the beats for six seconds. Multiply that number by 10 to determine the total number of beats per minute. For example, if you count 14 beats over six seconds, the total number of beats per minute is 140. Compare the total number of beats with your training zone as identified in Diagram 8. If necessary, increase or decrease your activity level to bring your heart rate into your training zone.
Maintaining the 903 Manual Treadmill The 903 treadmill requires little maintenance. Periodically, you need to clean the treadmill and possibly realign the running belt. Instructions for these procedures are provided in this section. At the end of this section, you will find information about how to receive additional service. Cleaning the Treadmill CAUTION: A special lubricant exists between the treadmill’s running belt and deck.
Diagram 9 Storing the treadmill. Deck Side rail Running belt Handrail T-knob Front lift bar CAUTION: Do not try to lift the rear of the treadmill by holding onto the rear roller as you may cause injury to yourself. To store the treadmill in a vertical position as shown in Diagram 9 and free up floor space when the treadmill is not in use, take the following steps: 1. Follow steps 1 through 3 above to lock the handrail into its lower position and then, move to the rear of the treadmill.
To check the alignment of the running belt, take the following steps: 1. Walk on the treadmill while holding onto the handrail for balance. 2. Observe the running belt for a couple minutes. 3. If the running belt tracks off center or the belt moves toward either flywheel, you need to align the belt. 4. If you see that the running belt is noticeable off center, adjust the alignment of the belt using the supplied hex key on the adjustment bolts (located at the rear of the treadmill). See Diagram 10.
Lubricating the Running Belt Over an extended period of time, you may notice that the running belt does not slide as easily as it did when you first purchased the treadmill and adjusted the elevation tubes according to Table 1 on page 7. Make sure that the microadjustment knob is turned clockwise as far as it will go to release all tension from the flywheel resistance belt.
