CAUTION! If you experience chest pains, nausea, dizziness,
or shortness of breath, stop exercising immediately and con-
sult your physician before continuing.
CAUTION! Any changes or modifications to this equipment
could void the product warranty.
CHAPTER 2: IMPORTANT SAFETY INSTRUCTIONS
2.1 READ AND SAVE THESE INSTRUCTIONS
To ensure your safety and protect the equipment, read all
instructions before operating the MATRIX U7x-01 Bike.
To ensure proper use of the Matrix U7x-01 Bike, make sure that all
users read this manual. Remind the users that before undertaking
any fitness program, they should obtain complete physical
examinations from their physicians. If, at any time while exercising,
the user experiences dizziness, pain, or shortness of breath,
nausea or feels faint, he or she must stop immediately.
* This bike is only to be used for its intended purpose described
in this manual. Do not use attachments that have not been recom-
mended by Matrix.
* Never drop or insert objects into any opening. Keep hands away
from moving parts. If the item cannot be reached, contact a Matrix
authorized dealer for assistance.
* Never operate the unit if it is damaged, not working properly, when
it has been dropped, or has been dropped in water.
* Keep hands and feet clear at all times from moving parts to avoid
injury.
* Do not use this product outdoors, near swimming pools or in areas
of high humidity.
* Do not operate where aerosol (spray) products are being used or
when oxygen is being administered.
* Do not use this product in bare feet. Do not wear shoes with heels,
leather soles, cleats, or spikes while exercising.
* Do not remove the side covers. Service should only be done by an
authorized service technician.
* Close supervision is necessary when used near children, invalids,
or disabled people.
* When the bike is in use, young children and pets should be kept at
least 3 meters / 10 feet away.
* Assemble and operate the bike on a solid, level surface.
* Never face backward while using the Matrix U7x-01 Bike.
* Use the stationary handlebars when mounting or dismounting the
bike.

CHAPTER 2: IMPORTANT SAFETY INSTRUCTIONS
2.2 ELECTRICAL REQUIREMENTS
The Matrix U7x-01 Bike can operate without power; however, the
machine must boot the software with each new user. This can mean
a delay of up to 35 seconds while the machine's operating system
prepares for a workout. It's similar to turning your cell phone on for
the first time of the day. These units can also be AC powered. This
will power the console at all times and requires no minimum RPM
for operation. A powered product lowers the starting resistance and
is easier to use for beginners. These units can be daisy chained
together, up to 4 units per dedicated 15 amp circuit, using a Matrix
daisy chain cord adapter (sold separately).
For your safety and for the performance of your Matrix bike, the
ground on your circuits must be non looped. Please refer to NEC
articles 210-21 and 210-23. Any alterations to the standard Matrix
power cords will void all warranties.
GROUNDING INSTRUCTIONS:
The Matrix U7x-01 Bike must be grounded. If it should malfunction
or break down, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. The bike is
equipped with a cord having an equipment grounding conductor and
a grounding plug. The plug must be plugged into an appropriate
outlet that is properly installed and grounded in accordance with
all local codes and ordinances. If the user does not follow these
grounding instructions, the user could void the Matrix limited
warranty.
DANGER: Improper connection of the equipment grounding
conductor can result in the risk of electric shock. Check with a
qualified electrician if the user is in doubt as to whether the product
is properly grounded. Do not modify the plug provided with the
product if it will not fit the outlet, have a proper outlet installed by an
electrician

Preventative maintenance and daily cleaning will prolong the life and
look of your MATRIX U7x-01 Bike
Please read and follow these tips.
* Position the equipment away from direct sunlight. The intense UV
light can cause discoloration on plastics.
* Locate your equipment in an area with cool temperatures and low
humidity.
* Clean with a soft 100% cotton cloth.
* Clean with soap and water or other non-ammonia based all pur-
pose cleaners.
* Wipe seats, pedals, console, heart rate grips, and the handlebar
clean after each use.
* Do not pour liquids directly onto your equipment. This can cause
damage to the equipment and in some cases electrocution.
* Check pedal straps weekly for wear.
* Adjust leveling feet when equipment wobbles or rocks.
* Maintain a clean area around the equipment, free from dust and
dirt.
DO NOT use any equipment that is damaged or has worn or
broken parts. Use only replacement parts supplied by Matrix
Fitness Systems.
MAINTAIN LABELS AND NAMEPLATES. Do not remove labels
for any reason. They contain important information. If unreadable
or missing, contact Matrix Fitness Systems for a replacement at
866-693-4863 or www.matrixfitness.com.
MAINTAIN ALL EQUIPMENT. Preventative maintenance is the
key to smoothly operating equipment. Equipment needs to be
inspected at regular intervals. Defective components must be
kept out of use until they are repaired. Ensure that any person(s)
making adjustments or performing maintenance or repair of any
kind is qualified to do so. Matrix Fitness Systems will provide
service and maintenance training at our corporate facility upon
request or in the field if proper arrangements are made.

CHAPTER 3: PREVENTATIVE MAINTENANCE
3.3 CARE AND MAINTENANCE INSTRUCTIONS
In order to maximize life span, and minimize down time, all MATRIX
equipment requires regular cleaning, and maintenance items
performed on a scheduled basis. This section contains detailed
instructions on how to perform these items and the frequency of
which they should be done. Some basic tools and supplies will be
necessary to perform these tasks which include (but may not be
limited to):
* Metric Allen wrenches
* #2 Phillips head screwdriver
* Adjustable wrench
* Torque wrench (capability to read foot lbs and inch lbs)
* Lint free cleaning cloths
* Teflon based spray lubricant such as "Super Lube" or other Matrix
approved products.
* Mild water soluable detergent such as "Simple Green" or other
Matrix approved products
* Vacuum cleaner with an extendable hose and crevasse tool
attachment.
You may periodically see addendums to this document, as the
Matrix Technical Support Team identifies items that require specific
attention, the latest version will always be available on the Matrix
web site at www.matrixfitness.com.
DAILY MAINTENANCE ITEMS
1) Look and listen for loose fasteners, unusual noises, and any
other indications that the equipment may be in need of service.
2) Clean the bike before and after each use, including:
a. Use a damp, soft cloth with water or mild liquid detergent
to clean all exposed surfaces. DO NOT use ammonia, chlorine, or
any acid based cleaners.
b. Keep the console display free of fingerprints and salt build
up caused by sweat.
WEEKLY MAINTENANCE ITEMS
1) Frequently vacuum the floor beneath the unit to prevent the
accumulation of dust and dirt which can affect the smooth operation
of the unit.
2) Check the pedal straps for damage.
3) Clean the grooves on the foot pedals.
MONTHLY MAINTENANCE ITEMS
1) Inspect the console, seat, pedals, and shrouds for damage.
2) Tighten the pedals onto their respective cranks using a 15 mm
wrench.
3) Adjust the leveling feet if equipment rocks or wobbles.
QUARTERLY MAINTENANCE ITEMS
1) Remove the front shrouds and check the belt for damage,
alignment, and proper tension.

4.5 WORKOUT SETUP STEPS - FITNESS TEST
FITNESS TEST -The Cooper Fitness Test measures cardiovascular fitness and proves an estimated sub-maximal VO2 result. It is based
on power output according to ACSM standards and was developed by the Cooper Institute© (www.cooperinstitute.org). User RPMs must
remain between 60-80 RPM during the test. The test will end when the user can no longer maintain this speed. Use of a heart rate strap is
optional but provides more data.
The test starts at a low intensity level and gradually increases in intensity (difficulty) every 2 minutes. As it increases, the user must maintain
60-80 RPM to advance to the next level. The test could take upwards of 30+ minutes for very fit individuals. Once the test ends a recovery
period (cool down) will begin and the user's results are calculated and displayed. Results are based on the number of stages completed.
Incline will not be adjustable during the test.
