4. Apply maximum resistance, fully turn the resistance knob in the clockwise (+) direction.
5. Adjust the left and right brake pads so that the magnetic gap fixture tool touches the fly-
wheel surface. Then fully tighten the 3 mm hex key fasteners (2x per pad).
6. Loosen the resistance and remove the magnetic gap fixture tools from the left and right
brake pads.
7. Verify resistance operation:
a. Turn the resistance knob to minimum resistance.
b. Start pedaling the bike at 60 rpm or greater while increasing the resistance level
to maximum and returning to minimum resistance. Stop pedaling and allow the fly-
wheel to stop:
l
Verify that changing the resistance level from minimum to maximum and
back to minimum was smooth and that there were no issues with the res-
istance knob or caliper assembly.
l
Verify that at maximum resistance, the pedal resistance was very strong (If
possible, compare with a similar bike in known good operating condition).
l
Verify that there were no unusual noises from the brake pads during this
operation.
8. Verify the power (watts) measurement:
(Spinner

Chrono™ Power model only)
a. Auto-cal the bike:
l
Set the resistance to minimum.
l
Start pedaling the bike at 55 rpm or greater, then slow down and allow the
pedals to stop. When the flywheel stops, the bike will perform the power
measurement auto-cal. Wait a minimum of 10 seconds for the auto-cal to
complete.
