unpacked the treadmill, under the front of the unit to lift the flywheel

off of the floor.

b. Remove the four bolts and washers from the front lift bar and set

them aside.

c. Slide the front lift bar brackets into the side rail mounts.

Note: You may need to ask for assistance to help you lift the front of

the treadmill to align the front lift bar brackets into the side rail

mounts.

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.

To determine if you have set the proper elevation for your height, stand on

the running belt with your hands on the handrail for balance. Your feet

should slide slowly and easily away toward the rear of the treadmill.

Continue walking and when you are comfortable and well-balanced on the

treadmill, release your grip on the handrail. 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 moving

the elevation tube up one more setting.

Note: 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. Remember that you want to be

able to maintain your momentum on the running belt without having to

push off from the handrail. A lubrication kit, available from your local

dealer, can be used as the equipment ages or friction (between the running

belt and deck) increases. If you do lubricate the deck, you may need to

change the elevation setting. See

Obtaining Service

either side of the handrail and gently tip the treadmill onto its side opposite

the micro-adjustment knob. See Diagram 4. Be sure the treadmill is

balanced and secure on its side and the micro-adjustment knob is

not

resting on the floor, before you let go of the handrail.

3. Adjust the Elevation Tube.(Diagram 5) The elevation tube has six settings

(refer to Table 1). To move the height adjustment pin to another setting,

take the following steps.

Important: Due to the weight of the treadmill, always adjust the elevation

tube while the treadmill is resting on its side. Making adjustments in this

manner also alleviates the possibility of injury.

a. Remove the height adjustment pin by pushing up on the locking

portion that wraps around the tube. Use your fingers to pull the pin

out of the elevation tube hole. Repeat this step on the opposite side.

See Diagram 5. Set the height adjustment pins aside.

b. Slide the elevation tube so that the elevation tube and front lift bar

holes align at the proper setting.

Make sure that the settings are the

same for both sides of the elevation tube.

c. Re-insert the height adjustment pins and push down on the portion

that wraps around the tube to secure the pin into position.

d. Return the treadmill to an upright position, so that the base is flat on

the floor.

CAUTION: Be sure that the

T-knobs are secure and locked

into position on both sides of

the handrail before performing

this step.

CAUTION: To avoid injury, do

not place your fingers

between the locking portion of

the height adjustment pin and

the elevation tube.

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. 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 determine that the belt needs alignment, follow the steps in

Aligning

the Running Belt

found in the maintenance section of this manual.

Once the treadmill is assembled, be sure to check the alignment of the belt

periodically. Adjust the running belt as soon as it needs alignment to prevent

tearing or fraying of the belt. Any damage due to improper maintenance of the

running belt is not covered by the limited warranty.

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. This section

provides information about the following areas:

• beginning and ending your workout

• working out on the treadmill

• adjusting the resistance level

Beginning Your Workout

Prior to beginning a workout, make sure that you have completed the following:

• assembled your 903 treadmill—

Assembly Instructions

• adjusted the elevation tube settings—

Adjusting the Elevation Tube

• checked the running belt alignment—

Aligning the Running Belt

• stretched your lower body and back—

Working Out on Your 903 Treadmill

If a procedure has not been fully completed, refer to that section and complete

the tasks involved before beginning your workout.

To begin a workout, hold onto the handrail as you step onto the running belt.

Slowly, turn the micro-adjustment knob to adjust the resistance of the running

belt. You should adjust the resistance so that you can walk comfortably, but

maintain momentum without holding onto the handrail. For more information

about working out, refer to

Working Out on Your 903 Treadmill

and

Adjusting

the Resistance Level

Ending Your Workout

To end your workout, hold onto the handrail as you gradually reduce the speed

of the running belt till it comes to a complete stop. Step off the running belt

onto the floor. If you wish to store the treadmill, refer to the instructions found

Storing the Treadmill

Remember to incorporate a cool-down period into your workout. A cool-down

period helps you to gradually lower your heart rate and lessen excessive muscle

soreness or stiffness.

Working Out on the 903 Treadmill

Before using your treadmill, we recommend that you follow these instructions

and go through a preliminary demonstration of the treadmill. Then, you will be

more familiar with the treadmill when you begin your workout.

When using the treadmill, follow these general guidelines:

• At the beginning of a workout, take several minutes to bring your heart

rate into your training zone, as shown in Diagram 8 later in this manual.

• After your workout, walk slowly for several minutes to cool down your

body and lower your pulse rate.

• Gently stretch your lower body and back before and after a workout to help

prevent stiffness or soreness.

CAUTION: Before beginning

any fitness program, you

should have a complete

physical examination by your

physician.
