THIS UNIT IS INTENDED FOR HOUSEHOLD USE ONLY.

READ ALL INSTRUCTIONS BEFORE USING THIS TREADMILL.

WARNING

1. Before starting any exercise program, it is recommended that you consult your physician. Stop exercising if you
feel any unusual pain or dizziness.

2. To reduce the risk of electric shock, always unplug the treadmill from the electrical outlet immediately after using
and before cleaning.

3. To reduce the risk of burns, fire, electrical shock or injury to persons:
Plug the power cord of the treadmill directly into a dedicated grounded circuit carrying 15 amps (110 Volt model)

or 7 amps (220 Volt model). We recommend the use of a surge protector.

Grounding Instructions

This product must be grounded. If it should malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of electric shock. This product 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.

4. Position the treadmill on a clear, level surface. Do not place the treadmill on thick carpet as it may interfere with
proper ventilation. Also, do not place the treadmill near water or outdoors. Treadmill mats can usually be
purchased from your treadmill dealer. If the power cord is damaged, it must be replaced by a power cord from
Nautilus, Inc. Please contact your dealer or Nautilus.

5. The minimum “clear” distance around the treadmill is 20 inches (.5 meters) on each side and 79 inches (2 meters)
behind the machine

6. Position treadmill so that the wall plug is visible and accessible.

7. Inspect the treadmill prior to each use for worn or loose components and then correct, replace, or tighten prior to
use. Do not use the treadmill if any area is found to be in need of service.

8. Read, understand, and test the Emergency Stop Procedures on Page 4 before use.

9. Read, understand, and carefully follow all warnings, instructions, and procedures on the treadmill and in the

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.

Walking and Running Resources

If you wish to obtain more information about starting a walking or a running program, please refer to the following
websites:

• Walking Websites-

• The Walking Site- http://www.thewalkingsite.com
This site has some useful information for beginning walkers. The "Beginner" section has a detailed walking
plan to get you started.

• Running Websites-

• Runner’s World- http://www.runnersworld.com
This website has many useful links that give information such as "Beginning," "Training," and "Nutrition."
This site has information for runners of all levels- from beginners to experts.

The above websites are just the beginning of the vast amount of fitness related information you can find on the internet.

If you don’t have access to the internet, your local library will have fitness books. In addition, hiring a personal trainer
can be beneficial because they are able to assemble a custom walking or running workout program for you.

Good luck in achieving your fitness goals! The best time to start is NOW!
