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 —

this procedure three times and it still slips call Cybex Customer Service. Follow the next step to
be sure the belt is centered.
