Running Belt Maintenance
Belt and Deck
Belt and Deck
Wipe the belt surface and the deck area with a clean dry towel to minimize the effect of friction between the deck and the running belt. This should be done often to prevent premature wear of the deck, running belt, and the drive motor system. See the Service Schedule at the end of this chapter.
The running belt may become loose and slip on the drive roller with each foot plant. If it does, follow the Tension and Center the Belt procedure below. See the Service Schedule in this chapter for a minimum schedule for checking the belt tension.
Tension and Center the Belt
The running belt may become loose and slip on the drive roller with each foot plant. If it does, follow the Tension and Center the Belt procedure below. See the Service Schedule in this chapter for a minimum schedule for checking the belt tension.
Tension and Center the Belt
If the belt is slipping under each step perform this procedure:
Tools Required
3/4” Socket wrench
Tools Required
3/4” Socket wrench
Center and tension the running belt
1. Plug the power cord into the power outlet.
2. Turn the main power switch to the on (I) position.
3. Press the Quick Start key.
4. Press the Speed + to bring the speed up to 5 mph (8 kph). Allow the treadmill to run for a minute.
The lateral position of the running belt is correctly centered when the Cybex logo is centered between the inside edges of the two belt tracking slots. If the Cybex logo is not centered between the belt tracking slots, center the running belt with the following procedure.
5. Observe the Cybex logo position relative to the belt tracking slots with the treadmill running at 5 mph (8 kph).

While centering the running belt choose one bolt to adjust. Do not adjust both bolts.
6. Tighten the rear roller bolt on the side of the treadmill toward which the running belt is moving using a 3/4” socket wrench. For example: If the running belt moves to the right of the belt tracking slots, tighten the bolt on the right side of the frame, tighten about 1/2 of a turn (clockwise) and wait 30 seconds. If the running belt does not move back to the center of the belt tracking slots, make another adjustment to the same bolt. Once the running belt has been adjusted closer to the center of the belt tracking slots, use about 1/4 of a turn until the running belt has been stabilized.

1.Rear roller bolts
7. Check the belt tension after the running belt has been centered. Make sure the running belt tension is tight enough so that the running belt does not slip or hesitate when stepped on.
Walk on the treadmill at 3.5 - 4 mph (5.6 - 6.4 kph) and every 4th to 5th step throw your weight into your step to feel if the running belt is slipping. If slipping is felt, confirm it is the running belt slipping and not the drive belt. With the hood cover removed, observe movement at the drive belt and front roller.
Do not over tighten the running belt. Over tightening the running belt can cause the belt to stretch and require replacement. Continue procedure until running belt stops slipping.
8. Check running belt for centering position. If running belt is not centered, perform steps 5 and 6.

8. Check running belt for centering position. If running belt is not centered, perform steps 5 and 6.
Checking the Running Belt and Deck Surfaces
The running belt and deck should be checked periodically for any excessive wear. In an effort to make sure that the running belt operates properly, visually inspect the belt often to make sure that there are no tears or fraying in the belt material. The running belt should be replaced every 15,000 miles (24,140 km). The running deck should be flipped every 15,000 miles (24,140 km) and replaced every 30,000 miles (48,280 km). A service prompt will appear at this interval and the parts will need to be replaced. Inspect the edges of the belt as described below.
Tools Required
Phillips screwdriver
Disconnect the external power source
9. Toggle the on/off (I/O) power switch to the off (0) position.The on/off (I/O) power switch is located under the front end of the unit, or on the front right side panel.
10.Unplug the treadmill from the power outlet.
Check the running belt condition
1. Remove the two screws securing the right end cap using a Phillips screwdriver.

1. Screws (2)
2. Right end cap
2. Repeat step 1 for the left end cap.
3. Inspect the top surface, seam, and edges of the running belt while you roll it by hand. If the belt has any rips or looks excessively worn the belt needs to be replaced.
If the running belt and deck need replacement refer to a qualified service technician.
4. Install the screws securing the end caps removed in steps 1 and 2 using a Phillips screwdriver.

Maintenance Tips
Elevation Motor Lubrication
In time the elevation motor pivot points or tube nut may develop a squeak. Lubricate the upper and lower bolts and the spacers with a small amount of lithium grease. You can buy lithium grease at an auto parts store.
Static Electricity
Depending upon where you live, you may experience dry air, causing a common experience of static electricity. This may be especially true in the winter time. You may notice a static build-up just by walking across a carpet and then touching a metal object. The same can hold true while working out on your treadmill. You may experience a shock due to the buildup of static electricity on your body and the discharge path of the treadmill. If you experience this type of situation, you may want to increase the humidity to a comfortable level through the use of a humidifier.
