Breaking in the Equipment
Precor equipment does not require an actual break-in period.
However, moving components such as belts, gears, and
bearings can settle while the equipment is being stored or
shipped. This can cause the equipment to operate with a
small amount of roughness or noise when it starts up for the
first time.
The equipment usually returns to smooth operation after a
day or two of normal use. If it does not, contact your dealer
for assistance. For more information, refer to Obtaining
Service.
