Personal Safety
• Assemble and operate the treadmill on a solid, level surface. Locate the treadmill at least 4
feet from walls or furniture. Keep the area behind the treadmill clear.
• Check the M9.21i or M9.21si treadmill before each use. Completely assemble the treadmill
before using it.
• Turn OFF (O) and unplug the treadmill when adjusting or working near the rear roller. Do not
adjust the running belt when someone is standing on the unit.
• Keep all electrical components, such as the motor, power cord, and ON/OFF (I/O) switch,
away from water or other liquids to prevent shock. Do not set anything on the handrail,
electronic console, or hood. Never place liquids on any part of the unit.
• Always attach the safety clip to your clothing at waist level prior to beginning your workout.
The safety clip is connected by a cord to the magnetic safety key in the electronic console. If
you encounter difficulties, you can stop the running belt by pulling on the cord to disengage
the magnetic safety key from inside the console. To resume operation, the magnetic safety
key must be replaced.
• When the treadmill is not being used, remove the magnetic safety key and store it in a safe
place to prevent unauthorized use.
• Wear proper exercise clothing and shoes for your workout—no loose clothing. Do not wear
shoes with heels or leather soles. Check the soles of your shoes and remove any dirt and
embedded stones. Tie long hair back.
• Keep all loose clothing and towels away from the running surface. The running belt will not
stop immediately if an object becomes caught in the belt or rollers.
• Use care when getting on or off the treadmill. Use the handrails whenever possible. Step onto
the running belt when the speed is at or below 1 mile per hour (1.6 kilometers per hour).
Never step off the treadmill while the running belt is moving.
• Before the running belt begins moving (prior to your workout), and after it stops (at the end of
your workout), straddle the belt by placing your feet firmly on the right and left side platforms.
• Never turn ON the treadmill when someone is standing on the machine.
• Keep your body and head facing forward. Never attempt to turn around on the treadmill when
the running belt is moving.
• Do not rock the unit. Do not stand on the handrails, electronic console, or hood.
• Do not attempt to service the treadmill yourself other than the assembly and maintenance
instructions found in this manual.
• Do not overexert yourself or work to exhaustion.
• Stop your workout immediately if you feel any pain or abnormal symptoms, and consult your
physician
Precor Heart Rate Option—Safety Guidelines
The Precor Heart Rate Option was created and designed exclusively for Precor products. The
equipment is extremely sensitive—you should use the heart rate option with this in mind and take
time to read the following guidelines:
• Handle the Precor Heart Rate Option with care. Do not drop the equipment. It might damage
the transmitter and you could void the manufacturer’s limited warranty.
• Do not use the chest strap near strong electromagnetic radiation sources. Television sets,
electric motors, radios, and high voltage power lines can interfere with the heart rate signal
that is being transmitted to the receiver and might affect the heart rate readings that appear on
the electronic console.
page 3
• Use only one chest strap at a time inside the range of the receiver. If the receiver tries to
process several signals simultaneously, an incorrect heart rate reading could result. Be sure to
keep any other transmitters at least 5 feet (1.5 meters) away from the receiver on your M9.21i
or M9.21si treadmill.
• Keep the equipment dry. Although the chest strap should not be immersed in water, wetting the
electrodes and your chest will improve the initial performance. Note that perspiration on the
chest strap during workouts is normal and actually enhances the signal being sent from the
chest strap’s transmitter.
• To conduct the electrical impulses from your heart, the chest strap’s electrodes require a
certain percentage of salts and minerals in the water used to wet them. The electrodes continue
to transmit your heart rate reading as long as they are in contact with your skin and your skin is
providing enough moisture through your perspiration to keep the electrodes wet. However, if
the concentration of salts in your perspiration is not high enough to conduct electrical impulses
and send them to the receiver, your heart rate reading will appear erratic or not appear at all.
Some people cannot use the heart rate feature because they do not have the proper body
chemistry.
• Do not use the chest strap if you are taking any medication or have a cardiac pacemaker.
Inaccurate heart rate readings can occur due to medication or electrical impulses from the
cardiac pacemaker.
• Stretching or bending the electrode strips on the chest strap may cause the strips to lose their
conductivity. Handle the chest strap with care.
• After extensive use, the chest strap (transmitter) may wear out, causing inaccurate heart rate
readings. With every use, check the strap for excessive wear and replace it if necessary. See
Obtaining Service
in the maintenance section of this manual.
Precor treadmills are designed for the enjoyment of the serious runner as well as the dedicated
walker. By following the above precautions and using good common sense, you will have many safe
and pleasurable hours of healthful exercise with your Precor treadmill.
Information Regarding Use in the U.S.A. and Canada
Federal Communications Commission, Part 15
The M9.21i or M9.21si treadmill has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. The M9.21i or M9.21si treadmill
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the owner’s manual instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If the M9.21i or M9.21si treadmill does cause harmful interference to radio or television reception,
which can be determined by turning the M9.21i or M9.21si treadmill OFF and ON, you are encouraged to try to correct the interference using one or more of the following measures:
• Reorient or relocate the receiving antenna for your TV, radio, VCR, etc.
• Increase separation between the M9.21i or M9.21si treadmill and the receiver (TV, radio, etc.).
• Connect the M9.21i or M9.21si treadmill into a different power outlet—on a dedicated circuit
different from the one used by the receiver (TV, radio, etc.). No other appliance should be
plugged into the same power outlet that the treadmill is connected to.

This manual explains how to assemble, use,
and maintain the M9.21i or M9.21si Low
Impact Treadmill. The following conventions
are used in this manual:
“Note:” Contains additional information that
applies to the preceding text.
“Important:” Indicates information to which you
should pay special attention.
“CAUTION:” Indicates steps or information
necessary to prevent harm to yourself or
damage to the equipment.
“WARNING:” Provides instructions to prevent
electrical damage to the equipment and prevent
injuries to yourself or others.
“DANGER:” Indicates steps you must take to
prevent electrical shock.
Thank you for purchasing the Precor M9.21i or M9.21si Low Impact Treadmill which
feature several sophisticated and beneficial technologies:
Technology, Smart Rate®
Ground Effects allows the treadmill’s running bed to “float” on specially formulated elastomeric
springs which cushion impact and control lateral motion without diminishing the bed’s lively,
responsive feel. Because it’s fully suspended, the bed provides optimum shock absorption
anywhere your feet land, not just in the center of the running area.
Integrated Footplant Technology (IFT) is a microprocessor-regulated motor control system. This
patented technology collects motor and belt speed data, using it to monitor your workout and
enhance your safety and comfort. It replicates the natural walking and running motion of your
feet. By allowing slight, natural speed variations throughout your stride, Precor treadmills
reduce shock and pounding to your body.
The console’s display offers varying selections that provide motivating feedback about your
workout. The display also incorporates the latest in cardiac monitoring to provide Smart Rate® — a
visual aid that lets you, the user, see your heart rate with a glance. On the M9.21i or M9.21si, the
optional Precor receiver must be installed and the Precor Heart Rate Option chest strap worn,
before the graph on the display can light up with colored cells to indicate your exercise intensity.
The M9.21i Low Impact Treadmill offers an easy-to-understand electronic console that gives
motivating feedback about your workout. Professionally designed exercise options incorporate
the latest in exercise science. Three different modes enhance your workout capabilities: Manual,
Interval, Weight Loss, Random, and Heart Rate Control course which requires the Precor Heart
Rate Option kit. The Heart Rate Course monitors your heart rate within a target zone (usually
85% of your maximum heart rate) and automatically changes the incline to keep your heart rate
in that zone when you wear the chest strap during your workout.

CAUTION: Do not remove or otherwise bypass
the 3-prong plug with an adapter or extension
cord in order to use a non-grounded outlet.
Electrical damage can occur if the treadmill is
connected to an improper power source.
You do not need any special knowledge or experience to set up a M9.21i or M9.21si treadmill.
However, you must review and follow the instructions in this manual. If you do not assemble and
use the treadmill according to the following guidelines, you might void the Precor limited warranty.
Installation Requirements
Follow these installation requirements when installing the treadmill:
• Acquire the appropriate tools. In addition to the tools supplied in the hardware kit, you will
need a phillips head screwdriver to remove the hood from the treadmill.
• Fill out and mail the limited warranty card. The serial number is printed on a label located
underneath the treadmill on the left, rear corner of the running bed. Write the serial number
onto the limited warranty card and in this manual before assembling the treadmill. Refer to
Obtaining Service
• Set up the M9.21i or M9.21si treadmill on a solid, flat surface. Do not install the treadmill
on deeply padded, plush, or shag carpeting due to possible damage to the carpet and
machine. If the treadmill is installed in a carpeted area, place a piece of heavy cardboard,
plywood, or other solid, smooth, flat surface under the unit. If the floor is not even, the
running belt will not track properly. Refer to
• Locate the treadmill at least 4 feet from walls and furniture. Be sure to provide ample space
in front of the machine to allow easy access to the ON/OFF switch. Open space to the sides
and back of the machine makes for a safer mount and dismount and easier belt adjustment.
• Use a standard 120-volt household outlet. The M9.21i or M9.21si treadmill is for household
use only. Precor recommends plugging the treadmill into an outlet that is connected to a
dedicated 20 amp house circuit breaker. A 20 amp circuit breaker inside the treadmill also
helps protects the electrical and electronic components from sustained overloads. An integral
3-prong, grounded plug meets safety requirements and protects the machine.
