Running Belt Maintenance - CYBEX Pro+ Service Manual

Running Belt Maintenance

Belt and Deck – Clean the belt and the deck surfaces to minimize the effect of friction between the wood
deck and the running belt. Clean the underside of the running belt and the top of the running deck surface
by wiping them with a clean dry towel. This should be done often to prevent premature wear of the deck,
running belt, and the drive motor system. See the Service Schedule in this chapter to determine the
minimum recommended cleaning.
The running belt may become loose and slip on the drive roller with each foot plant. If it does, follow the
Tensioning and Centering the Belt in this chapter. 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
1. Tension the belt.
A. Use a 3/4" socket wrench to turn each bolt 1/2 turn clockwise. See Figure 1.
NOTE: Be sure to adjust each bolt equally on each side.
B. Turn the power on and press the
Figure 1
C. Press the Speed + - keys to bring the speed up to 3.5-4 mph (5.6-6.4 kph). Allow the treadmill
to run for a minute.
D. Observe the belt to be sure it stays centered. If it is not centered follow step 2.
E. 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 belt is slipping. If the belt does slip, use a wrench to equally tighten both
rear roller adjustment bolts 1/2 of a turn (clockwise). Adjust the belt until no further slipping is felt. If
the running belt continues to slip the drive belt could be loose. Follow the next step to be sure the
belt is centered.
! CAUTION: Be careful not to over tighten the belt. Over tightening the belt can cause the belt to
stretch and require replacement.
