chapter eight: Care and Maintenance
Clean the treadmill of dust and dirt that might accumulate under
and behind the treadmill. Vacuum small rubber particles that
accumulate alongside the belt and behind the treadmill — these
particles are from the soles of running shoes.
This procedure is used to ensure speed and incline accuracy. It
should be done following any moving of the treadmill to a different
location in your facility, as well as following any internal service.

If it does not, repeat steps 1 - 3. If it still does not calibrate
successfully, call your dealer for service.
