deck system. The belt/ deck friction may play a major role in the function and life of your
treadmill, thus requiring periodic lubrication. We recommend a periodic inspection of the
deck.
We recommend lubrication of the deck according to the following timetable:
Light user (less than 3 hours/ week) Every 60 days
Medium user (3-5 hours/ week) Every 45 days
Heavy user (more than 5 hours/ week) Every 30 days
