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.

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.

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.
