PREFACE

Regular use of the StairMaster® FreeClimber® exercise system is a safe and effective way to develop aerobic fitness while conditioning the major muscles of the lower body. To get the best results, and to keep your machine in peak operating condition, you should carefully read and follow the guidelines presented in this manual.

WHAT IS IN THIS MANUAL?

The first part of this manual includes sections on safety, installation, operating instructions, and preventive maintenance. The second part contains detailed information on problem troubleshooting and repair procedures. An Appendix at the end of the manual provides additional information for the owner.

Throughout this manual, console keypad keystrokes are enclosed in [ ]. The names of the keys and special console operational modes are shown in capital letters. For example, your machine is ready to use when the console displays "SELECT WORKOUT." Press [MANUAL] to start the MANUAL exercise program.

WHAT IS THE STAIRMASTER FREECLIMBER EXERCISE SYSTEM?

The StairMaster FreeClimber exercise systems are vertical climbing machines with an independent step action. The independent step action, combined with the patented pedal geometry featured on all StairMaster steppers, provides an aerobic workout equivalent to uphill running or climbing stairs, but without the high-impact pounding to the joints and muscles.

There are five FreeClimber models: the 4600 PT (Personal Trainer), the 4600 CL (Cordless), the 4400 PT, the 4400 CL, and the 4200 PT. All FreeClimbers feature the Quiet Drive transmission. The 4600 PT and the 4600 CL have an adjustable tilting, full-featured Liquid Crystal Display (LCD) console. The 4400 PT and the 4400 CL have an upright, rail-less design. The

4600 PT and the 4400 PT use an external power supply that is plugged into an AC wall outlet. The 4600 CL and the 4400 CL use power generated during a workout to run the electronics. The 4600 PT and 4600 CL have contact heart rate and telemetry (Polar®) heart rate monitoring. The 4400 PT and the 4400 CL feature telemetry heart rate monitoring. The 4200 PT uses an external power supply and the console has less feedback and fewer workout programs than the 4600 PT/CL and the 4400 PT/CL.

BASIC OPERATING INSTRUCTIONS

GENERAL GUIDELINES FOR SAFE OPERATION

!WARNING

THESE GUIDELINES ARE DIRECTED TO YOU, AS THE OWNER OF THE MACHINE. YOU SHOULD INSIST THAT ALL USERS FOLLOW THE SAME GUIDELINES.

YOU SHOULD MAKE THIS MANUAL AVAILABLE TO ALL USERS.

1.Obtain a complete physical examination from your medical doctor and enlist a health/fitness professional’s aid in developing an exercise program suitable for your current health status.

2.When working out for the first time, use the MANUAL exercise program at the lower speeds until you feel comfortable and capable of faster speeds.

3.The speed and duration of your exercise program should always be subject to how you feel. Never permit peer pressure to override your personal judgment while exercising.

4.Overweight or severely deconditioned individuals should be particularly cautious when using the machine for the first time. Even though such individuals may not have histories of serious physical problems, they may perceive the exercise to be far less intense than it really is, resulting in the possibility of overexertion or injury.

5.Although all equipment manufactured by StairMaster® Health & Fitness Products, Inc. has been thoroughly inspected by the manufacturing facility prior to shipment, proper installation and regular maintenance are required to ensure safety. Maintenance is the sole responsibility of the owner.

Page 9

BASIC OPERATING INSTRUCTIONS

YOUR FIRST WORKOUT ON THE STAIRMASTER® FREECLIMBER® EXERCISE SYSTEM

1.Warm up with light calisthenics and easy stretching exercises for at least five minutes before beginning your exercise program.

!WARNING

IF AT ANY TIME DURING YOUR WORKOUT YOU FEEL CHEST PAIN, EXPERIENCE SEVERE MUSCULAR DISCOMFORT, FEEL FAINT, OR ARE SHORT OF BREATH, STOP EXERCISING IMMEDIATELY. IF THE CONDITION PERSISTS, YOU SHOULD CONSULT YOUR MEDICAL DOCTOR IMMEDIATELY.

2.Hold onto the handlebars and step up onto the pedals. Stand up straight. The pedals will sink slowly toward the floor.

3.Select the MANUAL exercise program so you can control the pace of your first workout and get used to the exercise motion. Press [MANUAL] and then press [ENTER]. The console will return to

the start screen if you do not press [ENTER] within 60 seconds.

4.The console will prompt you to enter your body weight. Enter your weight in pounds (or kilograms if the console is set up for metric units). Correct entry errors by pressing [CLEAR] before you press [ENTER].

5.The console will prompt you to enter your intensity level. Enter your desired intensity level. Correct entry errors by pressing [CLEAR] before you press [ENTER].

6.The console will prompt you to enter the workout time in one minute increments between 5 and 99 minutes. Press [1], [0], [ENTER] to exercise for ten minutes. If you do not start exercising within 60 seconds, the console will return to the start screen.

Begin Exercising

7.Take deep, comfortable steps. Do not let the pedals touch the floor or contact the upper stop. When you begin to exercise, the MANUAL

Page 10

BASIC OPERATING INSTRUCTIONS

program starts at level three.

8.As you become comfortable with exercise motion, press

[LEVEL: ] and [LEVEL: ] to adjust your climbing speed.

9.Relax and stand up straight while exercising. Use the handlebars for balance (see Figure 5).

10.Select an intensity level that allows you to stay in the middle of the pedal range of motion. Faster is not always better. Exercise at a level that is consistent with your fitness level.

Rest Periods

11.You can stop and rest as many times as necessary for up to one minute for each rest period during all programs. To stop, either press [STOP] or step off the machine.The 4400/4600 PT console returns to the start screen if you rest longer than the allotted rest period. The 4400/4600 CL console will shut off if you rest longer than the allotted rest period. Follow the onscreen prompt to continue your work out after a rest period.

Cool Down

12.When you are finished with your workout, the machine will slow down and the message “GOAL ATTAINED” will be displayed. You can cool down on the machine by continuing to step. The console timer will continue to count up from the selected time, and the intensity level will default to level 3. If there is a time limit set on the console, the timer will last only until the maximum time has been met. For example, if the time limit was set for 30 minutes and you worked out for 25 minutes, the cool down period would last for 5 minutes, or until you stepped off the machine.

13.You can also cool down by getting off the machine walking or stretching for at least five minutes. Lift one foot slowly until the pedal arm contacts the upper stop. Place that foot on the floor. Repeat for the other foot. Do not let the pedals slam into the upper stops, since this may cause unnecessary wear and tear.

Page 11

BASIC OPERATING INSTRUCTIONS

Figure 5: Correct Exercise Position

Head - Keep your chin parallel to the floor. Avoid staring at your feet or the computer console. This posture will also enhance your breathing.

Back - Although the whole body is in a slightly forward slant, keep your back straight and avoid bending at the waist.

Hips/Torso - Keep your hips directly under you with the buttocks slightly contracted. Avoid letting your hips rock

from side to side with each step.

Legs - Use a full, pain-free range of motion with each step, straightening your legs as far as possible without causing discomfort or letting your knees lock out.

Chest/Shoulders - Keep your shoulders square and centered over your hips with your chest lifted.

Hands - Rest your hands lightly on the side rails or front handlebars. Excessive leaning on the side rails can reduce calorie burn by up to 20%.

Elbows - Keep both elbows slightly bent. If you have good balance and want to burn more calories, you can pump your arms back and forth as if you were running.

Knees - Keep your knees aligned with your toes. Avoid training with your knees too far past your toes and keep your feet pointing forward. Do not hyperextend your knees.

Feet - Place 3/4 of each foot on the pedals, heels slightly off the edge with your toes facing forward.

HEART RATE MONITORING

HEART RATE INPUT

Contact heart rate and telemetry (e.g., Polar®) heart rate signal detection is available. There is no default priority of heart rate input. If a telemetry signal is detected first, contact heart rate signals are inhibited from being detected throughout the rest of the workout session and vice-versa. There is also a short “lock out” period at the beginning of each workout session during which the console first detects a signal and then validates the signal type. The duration of this shorter, initial “lock out” period differs between telemetry and contact heart rate.

•Telemetry heart rate - after the initial belt signal is detected, the console will enter a validation phase in which four good heart beat signals within four seconds are required before

locking on telemetry heart rate signals for the duration of the workout session. During the validation phase the console will not recognize contact heart rate signals.

•Contact heart rate - after the initial contact sensor signal is detected, the console will enter a validation phase requiring a good heart beat signal within 10 to 15 seconds, or until the system acquires a valid signal. During the validation phase, the console will not recognize telemetry heart rate signals. The console will display a beating double heart icon that has the inner heart colored in while searching for a valid signal.

Locked/Non-locked Option

When the “not locked” option is selected the heart rate source signal is not fixed during the exercise (if the signal is lost, either input will be valid). If the “locked” option is selected, then the heart rate source signal is locked on the first detected signal during the workout. To set a heart rate signal input, or to turn off the heart rate option all together, perform the following steps:

1.On the console keypad, press [LEVEL: ] , [3], [2]. At this point the screen will display “HR INPUTS.” Press [ENTER] to select this option.

Page 13

HEART RATE MONITORING

2.There are four options to handle heart rate input signals. Press the [SELECT] key to scroll through the options until you find the one option that suits your needs. Press the [ENTER] key to select that option.

“BOTH HR ON “ - allows either telemetry or contact heart rate signals to be detected. Once the console has detected a valid input signal it will lock out the opposite type of signal for the duration of the workout session. For example, if you start out using contact heart rate then you are limited to using only contact heart rate during your workout session, even if the signal is lost while performing the workout, and vice-versa.

“BOTH NOT LOCKED” - allows either telemetry or contact heart rate signals to be detected. Does not lock out a particular input signal for the entire workout. This option will detect either input signal during a workout session, but only one at a time, and only until the other signal terminates.

“TELEMETRY ONLY “ - locks out contact heart rate signals and will only detect telemetry signals.

“HAND ONLY “ - locks out telemetry signals and will only detect contact heart rate signals.

“BOTH HR OFF “ - turns off the ability to detect any signal at all. Used in rare situations where there is excessive interference with the heart rate signals. *This option disables the Constant HR program and the Fitness Test program.

TELEMETRY HEART RATE (4600/4400 PT/CL ONLY)

The StairMaster® FreeClimber® 4600/4400 PT/CL features telemetry (Polar®) heart rate monitoring. The system consists of the receiver, located on the stepper, and a transmitter belt (purchased separately) worn across your chest. The monitoring function is activated as soon as you strap on the chest belt and step within range of the receiver in the machine. Two electrodes on the underside of the chest belt sense the heart rate signal and send it to the receiver. The heart symbol on the console pulses to indicate that the console is receiving a valid signal. A microprocessor in the console calculates the heart rate and displays it, in beats per minute, on the console.

Using the Transmitter Belt

!WARNING

PACEMAKER USERS SHOULD NOT USE THE POLAR

TRANMITTER BEFORE CONSULTING THEIR DOCTOR.

Before you put the transmitter belt on, wet the two electrode patches (the grooved rectangles on the reverse side of the belt). Secure the transmitter belt as high under the pectoral muscles (chest) as is comfortable. The transmitter belt should fit snugly and comfortably, and allow normal breathing. When the console detects a heart rate signal, heart rate is shown in the display automatically. Your heart rate in beats per minute and a pulsing heart icon are displayed on the console.

After the initial belt signal is detected, the console will enter a validation phase in which four good heart beat signals lasting four seconds are required before locking on telemetry heart rate signals for the duration of the workout session. During the validation phase the console will not recognize

TELEMETRY HEART RATE

contact heart rate signals. If you do not see a heart rate on the console, try one of the following:

•Move closer to the console.

•Tighten the elastic part of the chest belt.

•Adjust the belt higher or lower on your chest.

•Remoisten the electrodes.

•Test your chest strap with a machine that you know is working, or with a heart rate watch that you know is working.

•If possible, replace or exchange your console with a console (from the same type of machine) that you know is working and retest the machine.

•Verify that the console software has been set up properly for heart rate detection (see pg. 13-14).

Figure 6: Transmitter Belt

Maintaining the Transmitter Belt

Clean the chest belt regularly with mild soap and water, then dry thoroughly - residual sweat and moisture keep the transmitter active and drain the battery in the transmitter. Do not use abrasives or chemicals such as steel wool or alcohol for cleaning, as they can damage the electrodes permanently. You can order replacement belts from StairMaster, Polar Electro, Inc., or your local fitness store:

CONTACT HEART RATE

The StairMaster® FreeClimber® 4600 PT/CL features a digitized contact heart rate monitoring system. Through the use of stainless steel sensors built into the upper handles and sophisticated software, heart rate can be checked at any time during a workout. The heart rate is displayed on the console. Contact heart monitoring is standard on the 4600 PT/CL and optional on the 4400 PT/CL.

The contact heart rate system is very accurate (within 3% of the medical standard), but its ability to detect a heart rate signal is influenced by several factors. Movement of the muscles of the upper body produces an electrical signal (muscle artifact) that will interfere with the detection of the heart rate signal by the sensors. Movement of the hands while they are in contact with the sensors also produces interference. Calluses and hand lotion act as an insulating layer to reduce the signal strength. Also, the EKG signal generated by some individuals is not strong enough to be detected by the sensors. Typically, these individuals account for 5 - 7% of the population. These individuals should opt for the Polar® chest strap method of heart rate monitoring. Most people (between 93 – 95%) will not have a problem with the system provided interference from movement is minimal.

Using Contact Heart Rate

Contact heart rate input signals are acquired only during contact between your hands and the stainless steel sensors on the handrails. To use the contact heart rate feature, place your hands around the handles so that your hands touch both the top and the bottom of the sensors. After the initial contact heart rate signal is detected, the console will enter a validation phase requiring a good heart beat signal within 10 to 15 seconds, or until the system acquires a valid signal. During the validation phase the console will not recognize telemetry heart rate signals. The console will display a beating double heart icon that has the inner heart colored in while searching for a valid signal. If, during exercise, the heart rate displayed is erratic, it may be helpful to remove your hands from the handles, wipe them and place them back on the handles. In all programs, the heart rate is shown automatically in the display window the first time the sensors are touched.

WORKOUT STATISTICS

During the exercise program, the Stats keys are used to track workout statistics which are then shown in the display window. Pressing the [SELECT] key turns off the scanning feature and shows the statistic of choice in the display window. Continue to press the [SELECT] key until you reach the desired statistic. Pressing the [SCAN] key will prompt the console to cycle through the following statistics:

•Distance - Provides a cumulative total of the equivalent distance (in miles or kilometers), you would have traveled while riding a bicycle outdoors at the same relative intensity.

•Calories/Hour - Provides a running total of the number of calories burned during a workout.

•Rate - Displays the current steps per minute.

•Floors - Displays the equivalent number of floors climbed with an 8-inch step. There are 16 steps per floor, and 48 floors per mile.

•Level - Shows the current intensity level between 1 (the easiest) and 20 (the hardest).

•Watts - Displays the exercise intensity in watts (746 watts = 1 horsepower).

•METs - Gives you the relative energy cost of exercise. MET stands for multiples of the resting metabolic rate. While you are sitting quietly, your body consumes oxygen at the rate of about 3.5 milliliters per kilogram of body mass per minute. When you exercise, your body needs more oxygen in order to function. For example, exercising at 10 METs requires ten times the resting rate of oxygen consumption, or about 35 milliliters per kilogram per minute. During a workout, this key shows the current MET level. During the workout summary, the average MET level is displayed.

•Target Heart Rate - Available only during the Constant Heart Rate program. Shows the selected target heart rate.

At the completion of a workout, the statistic averages are calculated based on the accumulation of data during the workout program, and not not including the cool down period.
