3Operation Verification
About
Use the Operation Verification Checklist to verify the [[[Undefined variable Pro-
ductInfo.EqptType]]] operation. Verify the [[[Undefined variable ProductInfo.EqptType]]] oper-
ation at the completion of any maintenance procedure and when it is necessary to ensure that
the [[[Undefined variable ProductInfo.EqptType]]] is operating properly.
Operation Verification Checklist
Do an overall visual inspection of the bike looking for any loose hardware and/or missing
parts. .Repair and replace as needed.
Verify that the bike sets level and is stable on the floor, see "Bike Leveling Adjustment"
on page27.
Verify that the seat position is level and does not rotate or tilt. Tighten and adjust as
needed.
Verify that the seat height and forward/back adjustment work correctly.
lMake sure that the seat post up/down movement is smooth and that the pop-pins
lock at different positions. .
lMake sure the forward/back slider movement is smooth and the adjustment knob
locks the seat in position.
Verify that the handlebar height and forward/back adjustment work correctly.
lMake sure the handlebar post up/down movement is smooth and that the pop-
pins lock at different positions.
lMake sure the forward/back slider movement is smooth and the adjustment knob
locks the handlebar in position.
Set the resistance to minimum and pedal the bike at a moderate pace (55 rpm or
greater), increase the resistance to maximum and return to zero resistance.
lVerify that the resistance knob functions normally from min to max resistance.
lVerify that there were no unusual noises from the brake pads or flywheel during
operation.
lVerify that at maximum resistance, the bike was very hard to pedal.
Pedal the bike at a moderate pace (55 rpm or greater), stop pedaling and press down on
the resistance knob. Verify that the flywheel immediately begins to slow and quickly
stops.
Power (Watts) measurement auto-cal verification:
(Spinner®Chrono™ Power only).
lSet the resistance to minimum and pedal the bike at 55 rpm or greater.
IMPORTANT: The resistance must be set to minimum to correctly perform
auto-cal.
7

lStop pedaling and wait for the pedals to completely stop. Wait 10 seconds to allow
the bike to complete the power measurement auto-cal function.
lWhile continuously pedaling the bike at 60 RPM, verify that the measured
workout WATTS at minimum and maximum resistance levels is within spe-
cification.
ResistanceLevel Power (WATTS)
minimum ≤40 Watts @ 60 rpm
maximum ≥415 Watts @ 60 rpm
Power (WATTS) specification
IMPORTANT: The bike must be auto-cal'd before making the WATTS meas-
urement. Also, the bike must be continuously pedaled between the min and max
resistance WATTS measurements. If the pedals stop, a new auto-cal may occur
invalidating the measurements.
Generator verification:
(Spinner®Chrono™ Power only).
lPedal the bike at 60 RPM.
lVerify that the measured generator voltage (service menu GEN VOLT) and cur-
rent output (service menu GEN AMP) is within specification.
Generator Spec Power (WATTS)
Generator voltage (GEN VOLT) approx: 9 Vac @ 60 rpm
Generator current (GEN AMP) approx: 0.4 amps @ 60 rpm

Error Log & ASL1verification:
(Spinner®Chrono™ Power only).
lVerify that there are no current active error codes, view the service menu
ERROR LOG. If there are logged error codes, resolve them and clear the error
log (service menu CLEAR ERROR
lVerify the ASL blue state (Some facilities may choose to switch the ASL function
OFF, see ASL SETUP): Ride the bike and stop. Make sure that the console ASL
state is steady blue. If not, resolve any issues and reset the ASL to blue state.
Return to service
(Spinner® Chrono™ Power models only)
lAuto-cal the bike, set the resistance level to minimum, start pedaling greater than
55 rpm and then stop pedaling. Wait for the pedals to stop and dismount the bike.
lIf verification tests were successfully completed, return to service.

4Adjustment Procedures
About
Adjustment procedures provide you with the step-by-step adjustment instructions to bring sys-
tems and components into specification. Perform the adjustment procedures whenever a
trouble symptom points to a particular component and after a major component is removed/re-
placed.
Available Adjustment Procedures
"Brake Pad Adjustment" on page12
"Drive Belt Tension and Tracking Adjustment" on page16
"Generator Belt Tension Adjustment" on page24
"Bike Leveling Adjustment" on page27
AutoCal
(Spinner®Chrono™ Power bikes only)
AutoCal is an automatic power (WATTS) measurement calibration feature offered on
Spinner®Chrono™ Power model bikes. To insure accurate power (WATTS) results, an
AutoCal should be performed before starting a workout.
AutoCal removes strain gauge sensor and brake pad magnetic field errors from the Power
measurement (WATTS) results. Items you should know to perform a good AutoCal:
lAutoCal is performed every time the pedals stop moving for more than 3-5 seconds.
lThe resistance must be completely removed (resistance knob turned fully coun-
terclockwise) while AutoCal is being performed.
lThe brake pads must be correctly gaped to achieve a good AutoCal, see "Brake Pad
Adjustment" on page12.
Two use cases that can cause a bad AutoCal
There are two common use cases that can inadvertently cause an inaccurate AutoCal:
lExerciser momentarily stops and starts pedaling during a workout.
Momentarily stopping and starting the pedals during a workout for more than 3-5
seconds will start a new AutoCal. If the resistance was not set to minimum, the Autocal
will be bad resulting in inaccurate power WATTS measurements.
10
4 Adjustment Procedures
About

lAn exerciser quits a workout and dismounts the bike without setting the resistance level
to minimum.
In this case the bike will perform an inaccurate AutoCal because the resistance was not
set to minimum. The new exerciser will read inaccurate power WATTS results unless a
new AutoCal is performed with the resistance set to minimum.
Procedure
Review entire procedure before starting.
3. Set the resistance level to minimum (resistance knob turned fully counterclockwise):
4. Start pedaling the bike at 55 rpm or greater, then slow down and allow the pedals to
stop. When the pedals and flywheel stop, the bike will perform the power measurement
AutoCall. Wait a minimum of 10 seconds for the auto-cal to complete
IMPORTANT: The resistance knob must be set to the minimum resistance level to
correctly perform the auto-cal function. The WATTS parameter will be incorrectly com-
puted if the resistance knob is not set to minimum resistance level during auto-cal.
5. Verify the measured WATTS at minimum and maximum resistance levels:
a. Set the resistance to minimum.
b. Start pedaling and maintain the speed at 60 rpm as reported on the console RPM
indicator. While continuously pedaling, verify the measured WATTS at minimum
and maximum resistance levels. Continuously pedal between measurements.

IMPORTANT: The bike must be AutoCal'd before making the WATTS meas-

invalidating the measurements.

Brake Pad Adjustment
This procedure provides instruction to adjust the Magnetic Brake Pads.
The brake pad-flywheel gap must be correctly set to insure proper resistance level, auto-cal,
and power measurement (watts).
Perform the brake pad adjustment any time the brake pads are replaced or any condition were
the resistance is not performing correctly or the power measurement is not being correctly
computed.
Strong magnetic force
The brake pads have a very strong magnetic force and attraction to the flywheel or any fer-
romagnetic metal object. . The brake pads can easily be ripped from your grasp and snap
against the metal object damaging the pad. Be very careful to hold the brake pads tightly when
in close proximity to the flywheel during the brake pad removal and installation procedures.
CAUTION:The magnetic force of the brake pad is very strong and when in close
proximity to the flywheel (or any metal object) will quickly snap the pad against the fly-
wheel (or other metal) object causing damage to the brake pad magnets. Firmly hold
the magnetic brake pads during removal/installation procedures to avoid damaging
the brake pads.

ment procedure.
