Before You Assemble
Basic Assembly Principles
Here are a few basic assembly tips that can make assembly of the Bowflex® TreadClimber® exercise machine quick and
easy.
1. Gather the pieces needed for each step prior to starting the step.
2. Turning towards the right tightens all the bolts and locknuts on your
Bowflex®
TreadClimber®. Turning towards the left,
loosens them.
3. All of the tools needed for assembly of your
Bowflex® TreadClimber® exercise machine have been included. These tools
are only designed for one use. If damaged, substitute any commonly available 9/16” wrench and #2 screwdriver.
Note: A utility knife or scissors will be required during the unpacking and assembly process
(not included).
Select Your Workout Area
Select where you are going to put your Bowflex® TreadClimber® exercise machine carefully. The best place for your
TreadClimber
of your TreadClimber
Make sure that the location you choose has a 10A power outlet within reach of the TreadClimber
preferably to the right side of the machine where you will be less likely to step on the cord during dismount.
Note: The TreadClimber
circuit breaker is GFI, look for a test and reset button on them. If they have the test and reset button it is a GFI outlet
or circuit breaker.
Further, if you ever perform any repairs on your TreadClimber

Step 18: Calibration (TC3000
and TC5000 only)
Note: During calibration, observe the walking belt alignment.
Belts do not need to be perfectly centered, but if they
are far enough from center to cause a scraping sound,
follow the belt alignment instructions in the Owner’s
Manual.
Failure to calibrate your machine prior to use could result in
machine failure and could cause injury.
During the entire calibration process, stand on the side
foot support platforms or rubber mat only. Do not stand on
the walking belts during this entire process.
Note: Re-calibration is also neccessary in the event of a
power outage or if a component like a belt or motor
has been replaced.

18-1 Plug the power cord into the the wall outlet.
18-2 Turn on the Main Power Switch (See Figure 18-1).
18-3 Stand on the side foot support platforms or rubber floor
mat. Do NOT stand on the belts.
18-4 Hold down the POWER and SLOWER buttons. Insert the
Safety Key.
Note: If the Safety Key is not fully inserted into the safety
®
keyhole, the TreadClimber
will not operate.
18-5 Release the POWER and SLOWER buttons. The TIME
display will read “CAL”, PrSS”,”Strt”.
18-6 Press the START/STOP button to start calibration.
Note: The belts will start and stop and the displays will show
various numbers that relate to the calibration process.
Do NOT interrupt calibration.
18-7 Calibration will take about 3 minutes. When calibration
has finished “CAL” “PASS” will show in the TIME
display.
18-8 Remove and re-insert the Safety Key to clear the display.

When the Bowflex
TreadClimber® exercise machine has
completed calibration, you may begin your workout.

step sensor in the DISTANCE window as a heart and the
speed sensor in the SPEED window as a heart.

If Calibration Fails (Screen Displays “Cal Fail” Message):
This error usually indicates that the console is unable to determine the speed of the belts. Take the following steps:
1. Unplug the unit and remove the three back covers.
2. Hold a stiff business card, ID card, or other similar onto the inside of the drive pulley. Adjust the speed sensor towards the card until it just makes contact.
3. Remove the card.
4. Plug unit in and recalibrate.
If calibration is successful:
• Replace the three back covers.
If calibration is not successful:
• Leave plastic covers off and contact customer care for assistance. ( See Important Contact Numbers page at the
back of this manual).
Explanation of Calibration Display Messages (for information only):
During calibration, the TIME display will show you text messages updating you as to the status of calibration. When there
is no text message in the TIME display window, the other displays will show the following:
HEART RATE (TC5000 Only) – will show the status of the motor control relay.
• “ON” signifies the power relay is on and energizing the motor.
• “OFF” signifies the motor control relay is off and not energizing the motor.
CALORIES/CAL PER MIN – will show the version number of the software.
TIME – will show either a text message regarding auto-calibration (“d0nE”, “Strt”, etc.) or the actual Pulse Width
Modulation (PWM) number (a number that provides digital information about base unit functions to the console) if
START/STOP, FASTER or SLOWER is pressed during calibration.
MILES/TOTAL STEPS (DISTANCE/MILES for TC3000) – will show the calibration of the total step count.
SPEED – will display the actual belt speed during the calibration function.

Belt tensionIf belt hesitates or slips when walking on unit
it may be caused by either a loose walking belt
or a loose drive belt. To determine the cause
perform the following test: Stand beside TreadClimber® fitness machine and set speed to 2
MPH. Step on one treadle and attempt to stop
movement. If one belt stops but roller at rear
and other belt continue to turn walking belt tension should be adjusted. If both belts stop but
motor is still turning the drive belt tension should
be adjusted.
Walking belt tensionAdjust walking belt tension at the front of the unit
using the provided hex wrench on the exposed
adjustment bolts located on each side of each
front roller. Be sure to adjust both bolts on each
roller the same amount as to not disrupt belt
alignment. Tighten (turn clockwise) each adjustment bolt in full turn increments. After each
adjustment, restart unit and check to see if belt
slippage has been eliminated. Repeat if necessary. If slipping feel persists after several adjustments, stop and refer to drive belt checklist.
Drive beltUnplug power from unit. Wait 5-minutes to
ensure no residual power remains. Turn unit on
its side to expose its underside. Verify shipping
bolt has been removed. If bolt is not present,
return machine to upright posiition. Remove
left rear plastic cover to expose “v” belt drive
line and motor. Tighten nut on the motor tension

finished.
Belt alignmentBelt seam may be contacting metal belt guide
under treadle. Slight adjustment of belt should
alleviate noise. Follow belt alignment procedure
in Owner’s Manual.
Size of steps takenIn order for a step to register, the pedals must
pass each other completely. This ensures that
the magnet on the treadle passes the step sensor. Make sure treadles are not locked in treadmill mode and that they are moving enough to
register a step.
