Safety Information
Before beginning any fitness program, you should have a complete physical
examination by your personal physician.
Review this manual to become familiar with the M9.4 Electronic Treadmill
Ergometer operations. Be sure to read and observe the following guidelines
when using this treadmill:
• Read the Owner’s Manual and follow all instructions.
Note for Club Owners: To ensure the proper use and safety of the M9.4
treadmill, make sure that all users review this manual. Please make this
manual a part of your training program.
• Assemble and operate the M9.4 treadmill on a solid, level surface. Locate
the treadmill at least 4 feet from walls or furniture. Keep the area behind the
treadmill clear.
• Do not allow children on or near the M9.4 treadmill. Do not leave children
unsupervised around the treadmill.
• Check the M9.4 treadmill before each use. Do not use the treadmill if it is
not completely assembled or is damaged in any way.
• Keep hands away from moving parts.
• Do not use the M9.4 treadmill if you weigh over 350 lbs. The M9.4 tread-
mill is built to handle runners up to 350 lbs. at speeds up to 12 mph.
• 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 embedded stones. Tie long hair back.
• Keep all loose clothing and towels away from the treadmill running surface.
A treadmill running belt will not stop immediately if any object becomes
caught in the belt or rollers.
• Use care when getting on or off the M9.4 treadmill. Use the handrails
whenever possible. Do not get on or off the treadmill when the running belt
is moving.
• Before starting the running belt, straddle the belt by placing your feet firmly
on the right and left staging platforms. You should also step off the belt and
onto the staging platforms after turning off the treadmill.
• Do not 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 or climb on the handrails, electronic
console, or hood.

page 3
• Do not set anything on the handrail, electronic console, or hood. Never
place liquids on any part of the treadmill.
• Keep all electrical components, such as the motor, power cord, and
ON/OFF switch, away from water or other liquids to prevent shock.
• Do not use accessory attachments that are not recommended by the
manufacturer—such attachments might cause injuries.
• Do not attempt to service the M9.4 treadmill yourself. This treadmill does
not have any user-serviceable parts. See Getting Service at the end of this
manual for service information.
• Turn OFF the treadmill and wait for the belt to come to a complete stop
before adjusting or working near the rear roller. Do not make any adjust-
ments to the running belt when someone is standing on the machine.
• This treadmill is manufactured with six safe “fail-off” systems. If the tread-
mill encounters a problem, it will trigger a “fail-off” system, allowing the
running belt to come to a gradual stop. Continued use of the treadmill after
a fail-off system occurs is not recommended. Instead, have your treadmill
serviced as described in Getting Service later 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 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 M9.4 Electronic Treadmill Ergometer.

Setting Up the M9.4 Electronic Treadmill
Ergometer
2You do not need any special knowledge or experience to set up an M9.4
Electronic Treadmill Ergometer. However, you must carefully review and follow
the instructions in this manual. If you do not assemble and use this treadmill
according to the following guidelines, you could void the Precor warranty.
Installation Requirements
Follow these installation requirements when installing the treadmill:
•Set up the M9.4 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 placed on a carpeted
surface, place a piece of heavy cardboard, plywood, or other smooth, flat
surface under the unit to protect the carpet and treadmill.
•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 power 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. Precor recommends that you
plug the treadmill into an outlet with a dedicated 20 amp circuit breaker.
The treadmill comes with a 20 amp circuit breaker to protect the electrical
and electronic components from sustained overloads, and an integral
3-prong plug grounded for your safety and to protect the machine.
CAUTION: Do not remove or otherwise bypass the plug with an adapter
in order to use a non-grounded outlet.
Assembly Instructions
Follow these instructions to assemble the M9.4 treadmill:
1. Make sure that the treadmill is unplugged and turned OFF. Do not
assemble the M9.4 treadmill if it is plugged in and turned ON.
2. Remove the black hood by unscrewing the eight phillips-head screws.

13. Lay the treadmill on its right-hand side with the help of another person.
Note: Right and left are determined while standing behind the treadmill,
facing towards the front of the machine.
14. Locate the long shoulder bolt and 3/8" locknut in the hardware kit. Insert
the long shoulder bolt through the center of the lift platform and the lift tube.
Secure the lift platform and tube together by fastening the 3/8 " locknut to
the end of the shoulder bolt. Fully tighten the bolt with the hex key pro-
vided. (See Photo 5.)
15. Return the treadmill to an upright position, so it rests flat on the floor.
16. Replace the black hood that you removed in Step 1 and tighten the eight
phillips-head screws.
CAUTION: Precor recommends that two people move the treadmill to
its final location. A fully-assembled M9.4 treadmill is very heavy, and
might cause back strain if one person tries to move it.
17. If you need to move the treadmill, ask for assistance from another person.
Roll the treadmill on its front wheels to the new location by lifting the rear
end of the unit.
CAUTION: Do not remove or otherwise bypass the 3-prong plug with
an adapter in order to use a non-grounded outlet.
18. Plug the treadmill into a standard 120v household outlet. Make sure that no
other major appliances use the same circuit as the treadmill.
19. Continue to Checking the Alignment of the Running Belt to complete the
installation of the M9.4 treadmill.
