USING YOUR TREADMILL
A BEGINNER’S GUIDE
Getting Started
If you are over 45, or have had health problems, and this is your first step towards fitness, check with your physician
first.
Before you even get on your treadmill, stand along side it, and get used to the controls- raise and lower the speed and
incline, and get a good feel for the controls. Then get on, straddling the belt with both hands on the handrails. Turn the
machine on and set the speed at 1 or 2 MPH. Stand tall, look forward, and "paw" with just one foot several times. Then
step onto the belt, and begin walking. After you feel comfortable, slowly increase the speed to 2 or 3 MPH. Stay at that
speed for 10 minutes. Slowly bring the machine to a stop and step off.

Going Forward
Walk a mile at a steady pace, and record your time. It will probably take between 15 and 25 minutes. At 3 MPH, a mile
will take about 20 minutes. After you can do this a few times fairly easily, you can gradually increase your speed and
grade so you are getting a good workout that lasts 30 minutes. To begin a walking program, keep in mind that you are
in no big hurry. This is for lifetime health, not overnight magic.

How Often?

• The goal- three to five times a week, for 15 to 60 minutes.
• Schedule workouts in advance; workout even when you don’t want to.
• Control intensity of workout by speed and/or by incline.
• Start off with no elevation at first. As you want to increase workout intensity, begin to elevate the machine; it
is very effective.

Suggested Workouts
The Quickie-

• 15 to 20 minute workout to get the most bang for the time.
• Warm up for 2 minutes at 3 MPH.
• Increase speed to 3.3 MPH then to 3.6 MPH (2 minutes each).
• Add 0.2 MPH of speed every 2 minutes until you reach a speed where you’re breathing hard, but not panting.
Maintain this speed for as much time as you have, slowing by 0.2 MPH increments if you get out of breath.
Leave 4 minutes at the end to slow down to 3 MPH for a cool down.
• If you have a hard time reaching the breathe-hard intensity through speed increases, increase the machine’s
incline slightly. A small increase in incline will raise the intensity of your workout.
The Calorie Burner-

• This more intense workout helps you burn more calories.
• Warm up for 5 minutes at 2.5 or 3 MPH.
• Increase 0.2 MPH every 2 minutes until you find a challenging pace that you can maintain for 45 minutes.
• To boost your workout, walk for the duration of an hour long TV show.
• Increase the speed 0.2 MPH during every commercial break.
• Go back to your regular speed until the next break.
• This helps you increase the calorie burn during the ad and while your heart rate is elevated afterward.
• Leave 4 minutes at the end to walk at 3 MPH for cooling down.

What to Wear
All you really need are a good pair of shoes. Running shoes are not very good for walkers; choose walking shoes with
a firm heel counter- the hard piece at the back of the shoe that holds the heel in place- and plenty of room for toes so
they can spread out as they push off. Wear loose, comfortable clothes.

Stretching
At any level of walking, a stretching session is a good idea. Warm muscles respond better to stretches than cold ones, so
walk for five or ten minutes until you’re warm. Then stop for the stretches listed below- fives times, 10 or more seconds
each, for each leg. Repeat at the end of the walk.

• Achilles Tendon and Calf- With both hands against a wall, place one foot behind you.

Keeping the rear leg

straight and its heel on the ground, lean in toward the wall. Repeat for the other leg.

• Quadriceps- Put your left hand on a wall or table for balance.

Then reach your right hand behind your back and

grasp your right ankle, pulling it gently towards your buttocks until you feel tension along the front of your thigh.
Repeat on other side.

•Hamstring- Stand on one leg and prop the other leg parallel to the ground on a table or cabinet top.

Slide both

hands toward the propped-up ankle as far as they’ll go. Repeat on other side.

HOW TO USE YOUR CHEST STRAP

CHEST STRAP
Using your chest strap, you can monitor your heart rate at any time during your workout or you can use a pre-programmed heart rate program.
How to use the chest strap:

• The chest strap will send your heart rate to the treadmill’s receiver and your pulse will be displayed within a
matter of several seconds.
• If your treadmill is equipped with heart rate programs, you will find an explanation of the heart rate programs
on the following pages in this user’s manual.

NUMERIC KEYPAD
The treadmill is equipped with a numeric keypad. This keypad may be used to enter weight, age, workout time, and
target heart rate. After entering any of these values, press ENTER to confirm and move to the next prompt. This keypad also enables you to enter speed and incline values during a manual (P1 - MANUAL) or user program (P12-14). See
“Fast Speed Entry” and “Fast Incline Entry” sections for more information.

Fast Speed Entry (Manual Mode, HRC, and User Programs ONLY)
During a manual program, heart rate control program, or user program, you may enter a speed on the numeric keypad.
You must press ENTER to confirm the new speed. You may enter values up to 11 MPH. Valid speeds are one to three
digits (to the tenth of a mile/hour). If you enter a speed that is not within this range, you will hear a reject tone and the
treadmill will remain at the same speed.

Example: During your workout, if you press 5 ENTER, the treadmill will run at 0.5MPH. If you press 72 ENTER, the
treadmill will run at 7.2MPH. If you press 103 ENTER, the treadmill will run at 10.3MPH.

CAUTION: The treadmill will adjust to the new speed when the ENTER key is pressed.
Fast Incline Entry (Manual Mode and User Programs ONLY)
Fast incline entries will work in manual or user programs. During your workout, you may press FAST INCLINE and
use the numeric keypad to enter an incline value. After pressing the desired incline level, you must press ENTER to
confirm the new incline level. You may enter values up to 12%. Valid incline levels are one to three digits and should be
entered in multiples of 0.5% (to the half of a percent). If you enter an incline level that is not within the range, you will
hear a reject tone and the treadmill will remain at the same incline level.

Example: During your workout, if you press FAST INCLINE 5 ENTER, the treadmill will adjust the incline level to
0.5%. If you press FAST INCLINE 15 ENTER, the treadmill will adjust the incline level to 1.5%. If you press FAST
INCLINE 105 ENTER, the treadmill will adjust the incline level to 10.5%. If you press FAST INCLINE 50 ENTER, the
treadmill will adjust the incline level to 5.0%.
CAUTION: The treadmill will adjust to the new incline when the ENTER key is pressed.

a visual and an audible warning before each segment change if there is a change in speed or elevation. The segments of
each program have a variety of speeds and inclines (See charts). To review your workout results, press START/STOP.
The program repeats until you choose to end the workout by following the "TO STOP" section.

O P E R AT I O N G U I D E
Programs 3, 4, and 6 are divided into 9 segments. Divide the program time by 9 to compute the length of each segment.
For example, if you choose a program time of 18 minutes, each segment will be 2 minutes long. The display gives a
visual and an audible warning before each segment change if there is a change of speed or elevation. The segments of
each program have a variety of speeds and inclines (See charts). To review your workout results, press START/STOP.
The program repeats until you choose to end the workout by following the "TO STOP" section.

However, before starting any exercise program, you should consult with your physician or health professional. He or
she can help establish the exercise frequency, intensity (target heart rate zone), and time appropriate for your particular
age and condition.
WEIGHT LOSS PROGRAM (P9)
This program is for those whose primary fitness goal is weight loss or fat reduction. The target heart rate is computed
as:
(220-age) x 65%
For example, the weight loss target heart rate for a 45-year old person is (220-45) x 65%. This equals a target heart rate of
114 beats per minute.
We recommend this program for a first time user. If the workout is too strenuous, lower the target heart rate by pressing
the INCLINE DOWN ARROW during the workout.
The weight loss program keeps you at your target heart rate by doing the following:
• There is an initial adjustment in incline when you begin the workout. The amount of adjustment is based on your
target heart rate value.

O P E R AT I O N G U I D E
• If your heart rate is 26 beats per minute (bpm) or more below the target, there is no additional adjustment in incline.
This allows for a warm-up period. Raise your speed to increase your heart rate.
• If your heart rate is 3 to 25 bpm below the target, the incline increases. When you are below the target zone, a green
heart flashes on the dot matrix display. This reminds you that you are below your target zone.
• If your heart rate is within 2 bpm of the target, there is no adjustment in incline. When you are within 3 bpm of the
target, an orange heart flashes on the dot matrix display. This reminds you that you are in your target zone.
• If your heart rate is 3 or more bpm above the target, the incline decreases. If the treadmill reaches minimum incline
and your heart rate is still above the target, a “decrease speed” message scrolls across the display. When you are
above the target zone, a red heart flashes on the dot matrix display. This reminds you that you are above
your target zone.
NOTE: The treadmill gives a visual and an audible warning before a change is made to your incline.
CARDIOVASCULAR PROGRAM (P10)
This program is for those whose primary fitness goal is to improve their aerobic fitness level and to improve sports performance. The target heart rate is computed as:
(220-age) x 80%
For example, the cardiovascular target heart rate for a 45 -year old person is (220-45) x 80%. This equals a target heart
rate of 140 beats per minute.
If the workout is too strenuous, lower the target heart rate by pressing the INCLINE DOWN ARROW during the workout.
The cardiovascular program keeps you at your target heart rate by doing the following:
• You will control your speed until you reach your target heart rate zone, which is + or – 3 beats per minute (bpm) of
your target heart rate. When you are below the target zone, a green heart flashes on the dot matrix display.
This reminds you that you are below your target zone.
• Once the target zone of + or – 3 bpm of the target heart rate has been reached or exceeded, the heart rate control
algorithm begins to control both your speed and your incline.
• If your heart rate is within 2 bpm of the target, there are no speed or incline adjustments made. When you are within
2 bpm of the target, an orange heart flashes on the dot matrix display.
This reminds you that you are in your target zone.
• If your heart rate falls below the target zone, a green heart flashes on the dot matrix display. Your speed is
automatically increased by 0.2 MPH every 15 seconds until you have reached your target zone.
• If the treadmill has increased your speed by 1 MPH* and you are still not within 2 bpm of your target, the treadmill
begins to raise the incline by 1% every 15 seconds.
• If your heart rate is 3 or more bpm above the target, the speed decreases by 0.2 MPH every 15 seconds until you reach
your target zone. When you are above the target zone, a red heart flashes on the dot matrix display.
This reminds you that you are above your target zone.
• If the treadmill has decreased your speed by 1 MPH* and you are still not within 2 bpm of your target, the treadmill
begins to decrease in incline by 1% every 15 seconds. If you are still above your target zone, lower your speed.
NOTE: The treadmill gives a visual and an audible warning before a change is made to your incline.
* The treadmill will only adjust your speed by 1 MPH maximum.

FITNESS TEST (P11)
The Fitness Test program measures the user’s baseline cardiopulmonary fitness level. Upon completion of the fitness
test, the user’s fitness scores will be given. This score can be used to compare the user’s fitness level progression as performance improves.
To use the program, the user must wear the included heart rate transmitter strap. It is important that the user enter their
correct age. The user’s age is used to calculate the target heart rate during the fitness test according to the following formula:

PROGRAM INSTRUCTIONS
1. Press POWER.
2. Adjust weight using ARROW (+ or -) keys or Numeric Keypad. Press ENTER.
3. Enter age using ARROW (+ or -) keys or Numeric Keypad. Press ENTER.
4. Select FITNESS TEST program 11 (P11) using PROGRAM or ARROW (+ or -) keys. Press ENTER.
5. The Target Heart Rate will be displayed in the HEART RATE window.
6. Set speed using SPEED ARROW (+ or -) keys.*
7. Press START/STOP.
8. The test begins when your Target Heart Rate is achieved, and will continue for three minutes.
9. At the conclusion of the test, read your Fitness Score in main display window.
10. Reference Table 1 to determine your fitness level.
* If you are an experienced treadmill user, pick the speed at which you normally walk or run for an
extended period of time.

TARGET HEART RATE = (220-age) *0.6*1.15
After you begin, you have a one-minute warm-up. The program then adjusts the incline level of the treadmill in a
similar fashion as used in the Heart Rate Control programs. Once the user reaches their target heart rate +/-5 bpm, the
TIME window starts a countdown from three minutes. During the three-minute period, measurements of incline, speed
and heart rate are used to calculate the user’s fitness score. The test is concluded at the end of the three-minute period
and the user’s score is displayed, along with total elapsed time for the test, heart rate, speed and incline at the conclusion of the test. Using the displayed fitness score, reference Table 1 to determine your fitness level.
Note - different user’s fitness scores cannot be directly compared without the use of Table 1.
If inexperienced or unsure of the most comfortable speed for the test, please refer to the following guidelines for suggested speed:

0 - 1.9 mph – deconditioned individual
2.0 - 2.9 mph – sedentary or new to exercise
3.0 - 3.9 mph – average walker
4.0 - 4.9 mph – accelerated walker
5.0 - 5.9 mph – easy paced jogger
6.0 - 7.9 mph – moderate paced jogger
8.0 - 9.9 mph – experienced runner
10.0 -11.0 mph – elite runner

* It is important for the test that walkers use
speeds of 4.9 mph or less and runners use
speeds of 5.0 mph or more.

USER PROFILES 1-4
Your treadmill is equipped with four user profiles. Using this feature offers the following benefits to a user:
• Quicker entry into programs- Each user profile stores previously entered values. User weight and age are always
remembered. In the preset programs, the treadmill remembers your workout time.
• Storage of cumulative workout data- Many users are interested in their fitness progress. Your treadmill displays the
following cumulative values for each user in a user profile: Total elevation gain, distance, calories burned, and workout
time.
• Storage of 3 personal programs- Each user profile contains three Personal Programs P12, P13, and P14. These custom programs remember your preferred speed and incline settings for 10 segments. Each user (1, 2, 3 and 4) may store
up to three unique programs in their profile.

USING PROFILES 1-4

Just like changing the oil in your car or replacing a filter in your home’s heating and cooling system, a little
preventive maintenance will insure your treadmill will operate smoothly and quietly for years to come.
WALKING BELT TENSION
As walking belts tend to stretch slightly with use, the walking belt may occasionally need to be tightened. If
the walking belt is too loose, you may find the belt stops while running or walking, while the motor continues to run. DO NOT OVERTIGHTEN THE BELT. This will cause reduced motor performance and roller
damage.

When properly tensioned, you should be able to lift the side of the belt about
2-3 inches (5-7.5 centimeters). A quick test for belt tension: you should be
able to fit three fingers under the edge of the belt.

To tighten belt:
Use the hex key provided with the treadmill (or a 3/16 inch hex wrench).
Place the hex key in the hole in left end cap and into the socket of the
adjustment screw. Turn key one full turn clockwise. Then place hex key in
hole in right end cap and turn key one full turn clockwise. Check the tension of the belt. Continue back and forth until belt is at the correct tension.
Make sure to adjust both sides equally to ensure correct belt alignment.
WALKING BELT CENTERING
The walking belt may occasionally need to be centered.
First be certain that belt is tensioned properly (see above).
Run the treadmill at about 3.5 mph (6 kph)
Place the hex key through the hole in the left end cap and into the socket of the adjustment screw.

If belt has moved to the right:
Turn the right adjustment screw 1/2 turn clockwise, then turn the left adjustment screw 1/2 turn
counterclockwise.
If belt does not move, repeat until belt is centered.

If the belt has moved to the left:
Turn the right adjustment screw 1/2 turn counterclockwise, then turn the left adjustment screw 1/2
turn clockwise.
If belt does not move, repeat until belt is centered.

1/2 TURNS
UNTIL BELT IS CENTERED
THEN RECHECK TENSION OF THE BELT

Then recheck tension of the belt (see above).

WARNING
ALWAYS UNPLUG THE TREADMILL FROM THE ELECTRICAL OUTLET
BEFORE CLEANING, LUBRICATING, OR SERVICING THE UNIT.
CLEANING
General cleaning of the treadmill will prolong the life of the treadmill and improve performance.

DANGER

Keep the unit clean by dusting regularly. Be sure to dust the exposed part of the deck on either side of the
walking belt and also the side rails.
For best performance, we recommend your treadmill be placed on a treadmill mat. Along with reducing
noise, a treadmill mat will help to keep dust debris away from your treadmill’s critical components.
Clean the top of the belt with a wet, soapy cloth. Be careful to keep liquid away from inside the motorized
treadmill frame or underneath the belt.

Dust and lint can accumulate under the motor cover and should be vacuumed out at least once a year. To do
so, FIRST UNPLUG THE UNIT. Then, remove the motor cover and carefully vacuum under the cover and
around the machinery. REPLACE THE COVER BEFORE PLUGGING THE UNIT BACK INTO THE
OUTLET.

AT T E N T I O N

CAUTION

WALKING BELT AND DECK LUBRICATION
