1.2 S

ETUP

Read the Operation Manual before setting up the Life Fitness treadmill. Place the treadmill
where it will be used before beginning the setup procedure.

ELECTRICAL POWER REQUIREMENTS

The Life Fitness treadmill is intended for use on a normal 120-Volt electrical circuit in the United
States and Canada. The following table provides the current rating for this product based on
supply voltage. Make sure that this treadmill model supports the proper line voltage for the
installation location before plugging it into the outlet.

G

ROUNDING INSTRUCTIONS

This Life Fitness product must be properly grounded. If the unit malfunctions or breaks down,
proper grounding provides a path of least resistance for the electric current, which reduces the
risk of shock to anyone touching or using the equipment. Each unit is equipped with an electrical
cord, which includes an equipment grounding conductor and a grounding plug. The plug must
be inserted into an outlet that has been properly installed and grounded in accordance with all
local codes and ordinances.

A temporary adapter MUST NOT BE USED to connect this plug to a two-pole receptacle in
North America. If a properly grounded, 20-amp outlet is not available, one must be installed by a
qualified electrician. Models drawing 16 amps or more must be installed on a dedicated line.

IL EST ABSOLUMENT INTERDIT d'employer un adaptateur temporaire pour brancher cette
fiche sur une prise à deux pôles en Amérique du Nord. Si aucune prise de 20 A correctement
mise à la terre n'est disponible, il convient d'en faire installer une par un électricien qualifié. Les
modèles utilisant 16 Aou plus doivent être installés sur des lignes qui leur sont réservées.

DANGER: A risk of electrical shock may result from improper connection of the equipment­grounding conductor. Check with a qualified electrician if in doubt as to proper grounding tech­nique. DO NOT modify the plug provided with the product. If it will not fit an electrical outlet,
have a proper outlet installed by a qualified electrician.

DANGER: Un branchement incorrect du conducteur de mise à la terre peut entraîner des risques de
décharge électrique. Consultez un électricien si des doutes subsistent quant à la technique de mise à
la terre. NE MODIFIEZ PAS la fiche fournie avec l'appareil. Si elle ne s'adapte pas à une prise, faites
en installer une correcte par un électricien qualifié.

EMOVING AND REPLACING THE WAX BAG

The wax lubrication system is a standard feature on the 91Ti model and international 90T model.
Treadmills with waxers are equipped to monitor wax levels automatically. On the 91Ti, when the the
wax bag is six-percent full, the console displays “NOTIFY MAINTENANCE -- WAXER NEEDS
REFILL”. When the bag is empty, the treadmill shuts down, and the console displays, “NOTIFY
MAINTENANCE -- WAXER EMPTY”. On a waxer-equipped 90T model, when the wax bag is six­percent full, the DATADISPLAY windows show “Err9”. When the wax bag is empty, the treadmill
shuts down and the DATADISPLAY windows show, “Err10”.

The wax bag is installed underneath the motor pan of the treadmill. To make replacing the bag
as easy as possible, use the UP LEVEL ARROW key to elevate the treadmill to the 15 percent
incline.

Before starting the procedure, turn the power off (“I”) at the ON/OFF switch, and unplug the unit
from the electrical outlet.

Open the wax tray: Pull out the three push rivets (A) that fasten the
front edge of the wax tray (B) to the bottom of the motor pan (C). If
necessary, use a flat-edge screw driver to pry off the rivets. The rivets
are reusable. Set down the front edge of the wax tray with the wax
bag on top of it.

Note: The rear edge of the wax tray is attached to the motor pan
during factory assembly.

Detach the old wax bag: Remove the motor cover. Engage (1) the wax bag hose clamp (D) to pre­vent any wax residue from seeping out of the bag. Then, gently work the wax bag hose off of the
barbed nozzle on the wax pump inlet hose located inside the motor compartment. Open (2) the hose
clamp, and slide it off. Discard the old wax bag.

Attach the hose clamp to the new wax bag: Slide the hose clamp (D) over the end of the new
wax bag outlet hose (E). Position the clamp approximately three inches from the end of the hose
and clamp it (1) onto the wax bag hose to prevent spillage.

Position the wax bag under the frame: Place the wax bag (F) on top of the wax tray, so that
the wax bag is directly underneath the treadmill motor pan (C), the wax bag flange is facing out
toward the front of the treadmill, and the wax bag hose is near the hole (G) at the bottom of the
motor pan through which the hose will be fed in the next step.

Connect the wax bag hose to the pump inlet hose: Cut off the end of the wax bag hose (E)
one half-inch from the end. Feed the hose through the hole (G) at the bottom of the motor pan,
and slide it onto the barbed nozzle on the wax pump inlet hose located inside the motor compart­ment. Be sure to fully seat the wax bag hose onto the inlet hose. Release (2) the hose clamp (D).

CAUTION: Failure to release the hose clamp greatly shortens belt life.

MISE EN GARDE : la bride de serrage doit être relâchée sous peine de réduire de
façon importante la durée de vie du tapis.

Close the wax tray: Align two holes of the wax bag flange with the two holes along the front edge

of the wax tray (B) and the two holes at the bottom of the treadmill motor pan (C). Attach the wax
tray and wax bag (F) to the motor pan with two of the push-rivets (A), simply by pushing each rivet
upward through both sets of aligned holes. Once each rivet is pushed through the holes as far as
possible, its front tip flares open to keep the tray and wax bag fastened to the motor pan. Push a
third push-rivet through the remaining aligned holes in the wax tray and the bottom of the treadmill
motor pan.

Inform the system that a new wax bag has been installed: Access the Manager’s Configuration.
For details, see Section 5.1, titled Entering and Using the Manager’s Configuration. On the 91Ti
model, scroll to the Refill Waxer System configuration setting. Press ENTER. The MESSAGE
CENTER displays “REPAIR LOGGED”. Press the CLEAR key three times to exit the Manager’s
Configuration. On the 90T model, select the Waxer System Installed configuration setting. Change
the setting to “no” by pressing the SPEED DOWN ARROW key once. Then, change the setting to
“yes” by pressing the SPEED UP ARROW key once. Press the STOP key once to exit the
Manager’s Configuration.

HOW TO POSITION AND STABILIZE THE LIFE FITNESS®TREADMILL

Following all safety instructions in Section 1.1, move the
treadmill to the location in which it will be used. See Section
7, titled Specifications, for the dimensions of the footprint.
Allow a distance of eight inches, or 21 centimeters, between
the treadmill and other units on either side. Allow a distance
of six feet, or two meters, from the rear of the treadmill to
any object or surface.

After placing the unit where it will be used, check its stability. If there is even a slight rocking motion
or the unit is not stable, determine which stabilizing leg is not resting on the floor. To adjust, loosen
the JAM NUT (A), and turn the STABILIZING LEG (B) until the rocking motion ceases, and both sta­bilizing legs rest firmly on the floor. Retighten the JAM NUT.

NOTE: It is extremely important that the stabilizing leg be correctly adjusted for proper opera­tion. An unbalanced unit may cause striding belt misalignment.

11

P

OWER SWITCH

Located on the front panel at the base of the treadmill, the ON/OFF switch has two positions:
"I" (one) for ON and "0" (zero) for OFF.

IMMOBILIZING THE

TREADMILL

An immobilized treadmill cannot be operated. The main motor, incline, and waxer are all disabled.
To immobilize the 91Ti treadmill, set the display to read “SELECT WORKOUT”. Press the STOP
key twice to do so if this message does not appear in the MESSAGE CENTER. Then, hold down
the SPEED DOWN key, and press the STOP key. The console for the immobilized treadmill dis­plays “IMMOBILIZED” in the MESSAGE CENTER. To restore operation, repeat the step of holding
down the SPEED DOWN key and pressing the STOP key. To immobilize the 90T model treadmill,
hold down the TIME DOWN key, and press the STOP key. The console for the immobilized tread­mill shows three horizontal lines in each of the data display windows. To restore normal operation,
repeat the step of holding down the TIME DOWN key and pressing the STOP key.

After installing and levelling the treadmill, check the belt to ensure that it is tracking properly.
First, plug the power cord into an appropriate outlet. See Electrical Requirements at the begin­ning of this section for details. Then, turn the treadmill ON (“I”).

Stand on the siderails of the treadmill and straddle the belt. Press the SPEED UPARROW key, and
increase the speed to 4.0 mph (6.4 kph).

If the striding belt moves to the right while it is running, have a second person turn the right ten­sion bolt a quarter-turn clockwise, and then turn the left tension bolt (A) a quarter-turn counter­clockwise. See the illustration below. This action sets the striding belt tracking back to center of
the roller.

If the striding belt moves to the left, turn the left tension bolt a quarter-turn clockwise and then
turn the right tension bolt a quarter-turn counter-clockwise to start the striding belt tracking back
to center of roller.

Repeat these adjustments until striding belt appears centered. Allow the belt to continue running
for several minutes to be sure that the tracking is stabilized.

NOTE: Do not exceed one full turn of the adjusting screws in either direction. If, after one full
turn, the belt does not track properly, contact Customer Support Services. The phone numbers
are listed in Section 6.7, titled How to Obtain Product Service.

EART RATE ZONE TRAINING EXERCISE

3.1 W

HY HEART RATE ZONE TRAINING EXERCISE?

Research shows that maintaining a specific heart rate while exercising is the optimal way to
monitor the intensity of a workout and to achieve maximum results. That is the idea behind the
Life Fitness heart rate zone training approach to exercise.

Zone training identifies an exerciser's ideal heart rate range, or zone, for burning fat or increas­ing cardiovascular fitness. The values within the zone depend on the workout.

Note: Consulting a fitness trainer is recommended for defining specific fitness goals and design­ing a workout program.

The Model 91Ti treadmill features exclusive workouts designed to take full advantage of the
benefits of heart rate zone training exercise: FAT BURN and CARDIO. Each workout offers
different benefits, as discussed in Section 4, titled The Workouts.

During one of these workouts, grasp the Lifepulse system sensors, or wear the Polar heart rate
chest strap to enable the on-board computer to monitor the heart rate. The computer automatically
adjusts the resistance level to maintain the target heart rate* based on the actual heart rate. To
change the target heart rate during a workout, use the SELECTARROW keys.

Although the Model 90T does not offer the FAT BURN and CARDIO workouts, it is equipped
with Polar telemetry heart rate monitoring. The Polar heart rate chest strap is sold separately for
both the Model 91Ti and the Model 90T.

19

* Target Heart Rate (THR) is a percentage of the theoretical maximum. For example, a 40-year-old user's THR for the CARDIO
workout is 144. This workout targets 80 percent of the maximum, so the equation would be (220-40)*.80=144.

EART RATE MONITORING

THE LIFEPULSETMDIGITAL HEART RATE MONITORING SYSTEM (91TI ONLY)

To use the treadmill's Lifepulse system to check the hear rate during a workout, grasp the sensors
(A) on the ErgoTMbar. Maintain contact with all four sensors throughout the workout to obtain a heart
rate reading. The console displays a heart rate within 20 to 30 seconds of contact with the sensors.

It is not recommended to grasp the sensors at speeds above 4.5 MPH, or 7.2 KPH. For these
speeds, the use of a heart rate chest strap is recommended.

THE POLAR®TELEMETRY HEART RATE MONITORING CHEST STRAP

The Life Fitness treadmill is equipped with Polar telemetry, a heart rate monitoring system
in which electrodes, pressed against the skin, transfer heart rate signals to the treadmill
console. These electrodes are attached to a chest strap that the user wears during the workout. The
chest strap is optional. For information on ordering, see Section 6.7, titled How to Obtain Product
Service.

See the diagram below for correct positioning of the strap. The electrodes (A), which are the two
grooved surfaces on the underside of the strap, must remain wet to transmit accurately the elec­trical impulses of the heart back to the receiver. Moisten the electrodes. Then, secure the strap
as high under the chest muscles as possible. The strap should be snug, but comfortable enough
to allow for normal breathing.

The transmitter strap delivers an optimal heart rate reading when the electrodes are in direct
contact with bare skin. However, it functions properly through a thin layer of wet clothing. If it
becomes necessary to re-moisten the chest strap electrodes, grasp the center of the strap, pull it
away from the chest to expose the two electrodes, and re-moisten them.

SELECTING A LEVEL (91TI ONLY)

The steps for setting up a HILL or RANDOM workout include selecting a level. The word “level”
refers to a range of incline percentages. The treadmill features 20 levels, with Level 1 having the
lowest average incline grade and Level 20 having the highest.

LEVEL % Incline LEVEL % Incline

1 0.0 - 1.5 11 2.0 - 8.5
2 0.0 - 2.2 12 3.0 - 9.2
3 0.0 - 2.9 13 3.5 - 9.9
4 0.0 - 3.6 14 5.0 - 10.6
5 0.0 - 4.3 15 5.5 - 11.3
6 0.0 - 5.0 16 6.5 - 12.0
7 0.0 - 5.7 17 7.0 - 12.7
8 0.0 - 6.4 18 8.0 - 13.4
9 0.5 - 7.1 19 8.7 - 14.1

10 1.5 - 7.8 20 9.0 - 15.0

Within each level are seven incline percentages, or hills. During a workout, each hill appears in
the WORKOUT PROFILE window as rows of light stacked in a column. The number of lit rows
within a column corresponds to an incline percentage. For example, in Level 5, the lowest
incline is 0.0 percent and is represented as one lit row. The highest incline, 4.3 percent, is repre­sented by a column with all seven rows lit. In the HILL and RANDOM workouts, these varying
hills occur for equal durations, as discussed in the HILL workout description. It is possible to

HILL

(91TI ONLY)

The Life Fitness-patented HILL workout offers a variety of configurations for interval training.
Intervals are periods of intense cardiovascular exercise separated by regular periods of
lower-intensity exercise. The WORKOUT
PROFILE window represents these high
and low intervals as columns of light, which together have the appearance of hills and
valleys. The computerized interval training workout has been scientifically demonstrated to pro­mote greater cardiorespiratory improvement than steady-pace training.

The HILL workout goes through four phases, each marked by different intensity levels. The WORK­OUT PROFILE window displays the progress of these phases. As noted in the descriptions below,
the heart rate should be measured at two stages in the workout to gauge its effectiveness. Wear the
chest strap or continuously grip the Lifepulse system sensors (91Ti only). The MESSAGE CENTER
does not display a request for a heart rate measurement, as it does with CARDIO and FAT BURN.

25

26

1 Warm-up is a phase of low, gradually rising resistance, which brings the heart rate into the

lower end of the target zone and increases respiration and blood flow to working muscles.

2 Plateau increases the intensity slightly, and keeps it steady, to bring the heart rate to the low

end of the target zone. Check the heart rate at the end of this phase.

3 Interval Training is a series of increasingly steeper hills, alternating with valleys, or stints of

recovery. The heart rate should rise to the high end of the target zone. Check the heart rate
at the end of this phase.

4 Cool-down is a low-intensity phase that allows the body to begin removing lactic acid, and

other exercise by-products, which build up in muscles and contribute to soreness.

Each column, as seen in the WORKOUT PROFILE WINDOW and the chart above, represents
one interval. The overall duration of the workout determines the length of each interval. Each
workout is made up of 20 intervals, so the duration of each interval is equal to the duration of the
entire workout divided by 20.

1 to 9 minutes: A workout with a duration of less than 10 minutes is insufficient for the HILL pro­gram to complete all four phases adequately. The program, therefore, condenses a workout of
this duration at various stages.

10 to 19 minutes: The interval durations initially are set at 30 seconds for a 10-minute workout.
For every minute over 10, each interval increases by three seconds. A15-minute workout
consists of 20 intervals at 45 seconds each.

20 to 99 minutes: All intervals last 60 seconds. If the user adds minutes to the pre-set duration
while the workout is in progress, the program adds hills and valleys that are identical to the first
eight intervals of the Interval Training phase. This pattern repeats until the workout is completed.

RANDOM (91TI ONLY)

The RANDOM program creates a terrain of hills and valleys that varies with each workout. More
than one million different patterns are possible.

26

27

FAT BURN (91TI ONLY)

The FAT BURN workout is designed to maintain a user’s heart rate at 65 percent of the theoretical
maximum†for optimal results. Throughout the workout, the user wears a chest strap or grasps the
Lifepulse system sensors (91Ti only). If the user is not wearing a grasping the Lifepulse system sen­sors or wearing the Polar heart rate chest strap, the WORKOUT PROFILE WINDOW displays a
heart shape, and the MESSAGE CENTER displays a prompt to grasp the sensors. The console
continuously monitors and displays the heart rate, adjusting the intensity level of the treadmill to
reach and maintain the target*. This system eliminates over- and under-training, and it maximizes
the aerobic benefits of exercise by using the body's fat stores for fuel.

CARDIO (91TI ONLY)

The CARDIO workout is virtually identical to FAT BURN; however the target heart rate is calcu-
lated at 80 percent of the theoretical maximum. The higher target promotes cardiovascular
improvement by placing a heavier workload on the heart muscle.

NOTE: Change the target heart rate for a FAT BURN or CARDIO workout at any time by using
the SELECT ARROW keys.

REVENTIVE MAINTENANCE TIPS

The Life Fitness treadmill is backed by the engineering excellence and reliability of Life Fitness
and is one of the most rugged and trouble-free pieces of exercise equipment on the market
today. Commercial Life Fitness treadmills are among the most popular of aerobic trainers,
regularly standing up to marathon use - 18 hours a day, seven days a week - in health clubs,
colleges and military facilities the world over.

NOTE: Safety of the equipment can be maintained only if the equipment is examined regularly
for damage or wear. Keep the equipment out of use until defective parts are repaired or
replaced. Pay special attention to parts that are subject to wear, as outlined below.

REMARQUE : pour conserver un matériel sûr, il convient de l'inspecter régulièrement afin de
déceler tout signe d'usure ou d'endommagement. N'utilisez pas l'appareil tant que les pièces
défectueuses n'ont pas été réparées ou remplacées. Portez une attention toute particulière aux
pièces qui s'usent, comme indiqué ci-dessous..

The following preventive maintenance tips will keep the Life Fitness treadmill operating at peak
performance:

• Clean the display console and all exterior surfaces regularly with mild soap and water or a
mild household cleaner. DO NOT use paper towels, ammonia or acid based cleaners.*

• Check operation of the emergency stop system once a week.

• Check the operation of the stop button once a week.

• Inspect and vacuum the area under unit regularly.

• Vacuum around the striding belt regularly to keep debris from accumulating.

• Inspect exterior parts regularly for wear, particularly the striding belt and deck.

• Check the position (centering) of the striding belt.

The optimum operating position of the striding belt is from 1.5 inches (38 mm) to 2.0 inches
(51 mm) from either side of the frame. If the striding belt travels beyond this position, see sec­tion 6.5, titled How to Adjust and Tension the Striding Belt, or contact Life Fitness Customer
Support Services, for proper alignment instructions, 1-800-351-3737 (USA). See section 6.6,
titled How to Obtain Product Service for customer support outside of the United States.

*NOTE: When cleaning the exterior of the unit, a non-abrasive cleaner and soft cotton cloth are
strongly recommended. At no time should cleaner be applied directly to any part of the equip­ment; use non-abrasive cleaner on a soft cloth and then wipe the unit.

ROUBLESHOOTING THE LIFEPULSE SYSTEM SENSORS

If the heart rate reading is erratic or missing, check the following:

• Dry moist hands to prevent slipping.

• Apply hands to all four sensors, two in each hand.

• Grasp the sensors firmly.

• Apply constant pressure around the sensors.

• Clean the sensors with a damp cloth.

6.4 TROUBLESHOOTING THE

POLAR HEART R

ATE CHEST STRAP

HEART

RATE READING IS ERRATIC OR ABSENT ENTIRELY

• Repeat the electrode wetting procedure. See Section 3.2, titled How to Use the Optional
Heart Rate Monitor Chest Strap. The electrodes must be wet to pick up and transmit accu-

rate heart rate readings.

• Make sure the electrodes are flat against the skin.

• Wash the belt transmitter regularly with mild soap and water.

• Make sure the chest strap transmitter is within three feet (one meter) of the heart rate
receiver.

• The chest strap is battery operated and will eventually stop functioning. If the chest strap
transmitter battery is depleted, contact Life Fitness Customer Support Services at 1-800­351-3737 for instructions on how to have the chest strap replaced.

HEART RATE READING IS ERRATIC OR EXTREMELY HIGH

When exercising with the optional heart rate chest strap, the user may come within range of
electromagnetic signals strong enough to cause abnormally elevated heart rate readings.
Possible sources of such signals include

• Television sets and/or antennas, cell phones, computers, cars, high voltage power lines and
motor driven exercise equipment.

• Another heart rate transmitter within three feet (one meter) may also cause abnormal heart
rate readings.

EMOVING THE ACCESSORY TRAYS

The accessory trays should be removed and cleaned periodically. See section 6.2, titled
Preventive Maintenance Schedule. To remove a tray, press inward the clip at the rear of the tray,
and pull the tray out. To reinsert the tray, line up the notch in front with small slit and snap the
top edge back into locked position.

6.6 HOW TO ADJUST AND TENSION THE STRIDING BELT

Do not move the treadmill or place hands under treadmill while it is plugged into an electrical
outlet!

THE BELT TENSIONING BOLTS

A 5/16-inch hex key wrench is required for this task. The Life Fitness treadmill has access holes
in the rear roller guards which allow access to the tensioning bolts. These tensioning bolts make
it possible to adjust the tracking and centering of the striding belt (A) without removing the
guards.

NOTE: It is extremely important that the treadmill be correctly leveled prior to any tracking
adjustments. An unstable unit may cause striding belt misalignment. See the topic titled How To
Stabilize the Life Fitness Treadmill in Section 1.2, titled Set Up, prior to attempting any rear roller
adjustments.

Before proceeding, it is helpful to visualize the REAR ROLLER (B) pivot point (C). Each adjust­ment made to one side of the ROLLER must be met with an equal and opposite adjustment (D)
to the other side of the ROLLER to maintain an ideal belt tension at the pivot point.

RACKING (CENTERING) A STRIDING BELT

Two people are needed to perform this procedure.
1 Locate the two access holes to the belt tensioning bolts on each of the rear roller guards.
2 Stand on the sides of the treadmill and straddle the belt, not standing on it. Start a MANUAL

workout, and set the belt speed to run at 4.0 mph (6,4 kph).

3 If the striding belt has moved to the right, turn the right tension bolt (B) 1/4 turn clockwise

with provided ¼" Allen wrench, and then turn the left tension bolt (A) 1/4 turn counter-clock­wise to start striding belt tracking back to center of roller.

If the striding belt has moved to the left, turn the left tension bolt 1/4 turn clockwise and then
turn the right tension bolt 1/4 turn counter-clockwise to start striding belt tracking back to
center of roller. Repeat adjustments until striding belt appears centered. Allow machine to
continue running for several minutes to observe if tracking remains stabilized.

NOTE: Do not exceed one full turn of the adjusting screws in either direction. If after one full
turn the belt does not track properly, contact Customer Support Services. The phone num­bers are listed in "How to Obtain Product Service."

NOTE: Do not exceed one full turn of the adjusting screws in either direction. If after one full
turn the belt does not track properly, contact Customer Support Services. The phone numbers
are listed in Section 6.7, titled How to Obtain Product Service.

ENSIONING AN EXISTING STRIDING BELT

1 Enter the Manual workout and run the treadmill for five minutes at 5.0 MPH (8.0 KPH).
NOTE: DO NOT RUN ON BELT.
2 Reduce the speed to 2.0 MPH (3.2 KPH). Walk on the treadmill. Tightly grip the handrails

and attempt to stall the striding belt. If the belt slips, continue to Step 3. If it does not slip,
the tension is correct.

3 Using the STOP key, stop the treadmill. Turn the belt tensioning bolts a quarter-turn clock-

wise for each side. Do not exceed one full turn (four quarter turns) per side.

4 Enter the MANUAL workout and run the treadmill at 2.0 MPH (3.2 KPH) check to insure

proper tracking. If the striding belt drifts to the left or right see the topic titled Tracking
(Centering) an Existing or New Striding Belt on the previous page.

Do not over-tighten the tensioning bolts while making belt adjustments. Over-tightening of bolts
may over stretch and damage the striding belt or roller bearings. Do not exceed one full turn of
either bolt in either direction.
