IMPORTANT SAFETY INFORMATION AND INSTRUCTIONS
•The Keiser M3X is NOT designed with a freewheel, but a fixed gear system. When the flywheel
is in motion, the pedals will also be in motion. Never remove your feet from the pedals while in
motion as serious user injury may occur. Always secure the pedal clip strap by placing your foot
on the pedal and in the toe cage. Locate the strap and pull up on it to tighten. It should be snug
but not too tight to cause discomfort.
•The resistance shifter allows you to safely slow or stop the motion of the flywheel. Move the
resistance shifter away from you to increase the gear and slow the motion of the flywheel. This
method can also be used as an emergency operation to stop the motion of the flywheel. To use
the resistance shifter as an emergency brake, move the lever all the way forward to stop all
motion within one revolution. With any braking procedure, wait until the pedals and flywheel
come to a complete stop before dismounting.
•The Keiser M3X is intended for cardiovascular fitness training. Consult a qualified physician or
fitness professional to determine an appropriate training routine and determine if cardiovascular
training should be a part of your exercise program. Serious injury or death can occur from
over-training and should be taken very seriously.
•
The Keiser M3X is to be operated in a commercial fitness environment, all use should be
supervised by a qualified fitness professional.
•Keep children and pets clear from the unit at all times, especially while in use.
•The Keiser M3X should be positioned on a stable, level, horizontal surface with a recommended
clearance of 18-24”/45-60cm on all sides.
•Movements such as pedaling at high speeds or pedaling while standing are considered
advanced techniques, and should only be performed when the rider has reached an advanced
level and has practiced basic cycling and pedaling techniques at slow to normal speeds.

M SERIES COMPUTER OVERVIEW
The M Series computer is a powerful teaching and programming tool. The computer can assist
both the instructor and participant by providing immediate feedback as well as tracking on-going
improvement.
By experiencing objective Cadence, Power Output, Gears and Heart Rate, the
participant benefits from a better overall and more effective workout. The computer can also be used
as a motivating tool to engage participants in their workouts. The more participants understand the
components of a proper workout, the further they can fine tune their performance. The goal is to work
more effectively and efficiently, and achieve better results.
LINE 1 BACKLIGHT SENSOR
While the M Series Computer is awake, the Backlight Sensor automatically detects ambient light
levels in the room and turns on the backlit display when needed.
LINE 2 RPM (CADENCE)
The RPM displays the cyclists Revolutions Per Minute on one crank arm. RPM is also known in the
cycling world as Cadence and is roughly the speed at which the cyclist is pedaling. At above 140
RPM the computer will not read and the word “STOP” will appear to indicate that the cyclist is
pedaling faster than he or she needs to be. If the cyclist is out of the saddle and wishes to retain the
sufficient resistance, pedaling should not fall below 60 RPM.
LINE 3 POWER
The Power Output is displayed in Watts (currently generating) and Kilocalories (total value for the
workout). The computer toggles back and forth between Watts (displayed for eight seconds) and
Kilocalories (displayed for two seconds) throughout the ride. Rated accuracy for Power is +5W for
Power below 50W, and +10% for Power above 50W.
LINE 4 HEART RATE
If there is no Heart Rate signal, a steady heart
symbol and a zero will be displayed. If a participant
is wearing a Heart Rate strap, once the computer
locks onto the signal, the heart symbol will blink
and display the heart rate. Please note that the
Heart Rate strap.
LINE 5 ELAPSED TIME
The number shown reports the total time spent
cycling and will reset to zero after 60 seconds of
inactivity or if computer is reset using the gear shifter.
•Ensure that all adjustment handles that could interfere with the user’s movement are not left
projecting as to come in contact with the rider during operation.
•Before dismounting, push the resistance lever to the most forward position to bring both the
flywheel and pedals to a complete stop. Loosen each pedal clip strap, remove your feet from the
pedals and dismount the bike.
WARNING: Heart rate monitoring systems
may be inaccurate. Over exercise may
result in serious injury or death. If you feel
faint stop exercising immediately.

LINE 7 ODOMETER/TRIP DISTANCE
For the first eight seconds when the computer is first activated, the Odometer will display the total
distance the cycle has been ridden. This feature is for service and maintenance purposes only. After
eight seconds, the Odometer will display Trip Distance.
AVERAGE CALCULATIONS
To view averages: RPM (Cadence), Power, and Heart Rate at any point in the workout, stop pedaling
for three seconds. This will flash your averages until you start moving again or until the computer
goes to sleep after 60 seconds.
RESETTING RIDE AVERAGES, ELAPSED TIME AND DISTANCE
To reset your averages during the workout, stop pedaling for three seconds and the averages will
start to flash, while they are flashing move the gear shifter from bottom to top two times quickly. This
will reset your workout information back to zero.
M SERIES COMPUTER CALIBRATION
All M Series cardio equipment is calibrated with a tool at the factory and there is no need to
calibrate, unless a component associated with the resistance mechanism or computer require
service. For more information visit: www.keiser.com/service, or contact the Keiser service
department at 1-800-888-7009 | 559-256-8000 | [email protected].
COMPUTER BATTERY REPLACEMENT
To test the computer batteries rotate the crank arm until the computer “wakes up”. If the battery
is low, a “LO-BA” will display in the Odometer (ODO) display at the bottom of the computer. To
replace the batteries unscrew the back of the computer housing and remove old AA batteries and
replace with a set of two new AA batteries. If you have multiple machines, we suggest all
computer batteries be changed at the same time.
WARNING: Do not burn batteries. Do not place batteries in waste bins. Batteries must be
disposed of by a Licensed Waste Collector. Battery leakage is extremely caustic and contact
with bare skin should be avoided. In the event that battery leakage comes in contact with your
skin, flush the area for 15 minutes with copious amounts of water and seek medical attention.
Gloves, overalls, safety shoes and eye protectors must be used when handling leaking
batteries. Follow manufacturer’s recommendations when handling and maintaining batteries.
!
WARNING: The safety level of the equipment can only be maintained if it is regularly
inspected for damage and wear. Immediately replace defective parts and do not use the
equipment until all repairs have been completed and thoroughly tested.

1. Each member should thoroughly inspect each M3X to make sure it is in safe and proper working order.
2. Each member should wipe off their own sweat after each class with a soft towel (their towel) or cloth.
3. Check and re-torque the screw holding the crank arm to the axle and the pedals. Also, check
and re-tourque the nuts securing the main frame to the bottom frame. The torque for all is 35
ft-lbs (47Nm).
4.
Thoroughly inspect each M3X to make sure it is in safe and proper working order. Pay particular
attention to loose screws, nuts & bolts, crank arms, pedals, pedal cages, handlebar, saddle,
T-Handle adjustments, worn pedal straps, etc.
5. Clean with warm water and a soft cloth the parts of the M3X that are dirty or come in contact
with sweat. Do not use household or industrial cleaners, because many of them are designed to
clean, glass, tile, porcelain, and greasy or oily surfaces and can destroy the protective finish of
the paint. If you need to use soap, use a mild dish washing soap followed by an automotive
treatment such as Meguiar’s Quick Detailer Mist and Wipe.
6. Check batteries. IF YOU HAVE MULTIPLE MACHINES, WE SUGGEST ALL COMPUTER
BATTERIES BE CHANGED AT THE SAME TIME (2 AA batteries per bike). See “Computer Battery
Replacement” section for instruction.
7. It is not necessary to wax the entire machine monthly, but it is very important to wax those
areas that come in contact with sweat and that are the most vulnerable to rust. Use an easily
applied automotive treatment such as Meguiar’s Quick Detailer Mist and Wipe. Please note that
failure to apply a coat of wax to high sweat areas at least once a month will decrease paint and
frame life due to corrosion and will void the warranty.
8.
Remove, clean, and lubricate the threads on the adjustment handle. Since both the threaded
stud and the threaded nut are stainless steel it is very important to keep the threads lubricated with
a heavy grease, preferably white or clear in color, such as Hydrotex MT-55 or Dow Corning 111.
9. Thoroughly inspect the X-Bar system on the dampening performance, looseness in the mechanism,
looseness on the mounting areas.
