3. Insert the Safety key, turn ON the treadmill, press the QUICK START key, and then increase
the running belt speed to 3 mph (5 kph) by pressing the SPEED ▲ key.
4. Observe the running belt for a couple of minutes. The belt should track centered on the
running bed.
5. Press STOP to stop the running belt.
6. If the belt needs additional alignment, repeat steps 1 through 5 of this procedure until the belt
is properly aligned.
Adjusting the Tension of the Belt
Proper belt tension is important for a smooth, steady run. If your physical condition permits, test
the belt tension by jogging at 6 mph (10 kph). If the belt tension is too loose, you will feel a pause
in the belt with each footplant (step).
To adjust the running belt tension, take the following steps:
1. Make sure that the treadmill is OFF (O). If the treadmill is ON ( I ), switch it to OFF. Wait for
the running belt to come to a complete stop.

2. Standing behind the treadmill use the rear belt adjustment bolts (see Diagram 17 on the
previous page and Diagram 18). Simply turn each bolt
clockwise
1/4 turn to adjust the tension
of the belt.
3. Insert the Safety key, turn ON the treadmill, answer the start-up prompts, then increase the
speed of the running belt to 6 miles per hour (10 kph) by pressing the SPEED key.
4. Jog on the running belt for 1 minute or more. If you feel a pause in the belt with each
footplant (step), you need to continue to adjust the belt tension.
5. Press STOP to stop the running belt.
6. Continue with steps 1 through 5 until the belt tension has been properly adjusted and you no
longer feel the pause in the belt with each footplant.
Important: Do not turn the adjusting bolts more than 1/4 turn at a time. Overtightening the
bolts can damage or cause premature failure of the precision bearings in the front and rear
rollers.
