Running Belt Maintenance
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 Tensioning and Centering 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
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. Press the Quick Start key.

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 belt to see if it still slips. If it does restart this procedure at step 1 A. If you
have to do this procedure three times and it still slips call Cybex Customer Service.
Follow the next step to be sure the belt is centered.
NOTE: Be careful not to over tighten the belt. Over tightening the belt can cause the belt to
stretch and require replacement.
