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 your owner's manual.
