provides a path of least resistance for electrical current to reduce the risk of electrical shock. The müüv
Treadmill 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 local codes and ordinances.

TREADMILL ADJUSTMENTS
RIGHT
ADJUSTMENT
LEFT
ADJUSTMENT
When adjusted properly, the inStride Treadmill’s WALKING BELT(10) will roll smoothly around the WALKING
BOARD(9) and over the front and rear rollers without catching or rubbing. For the belt to run smoothly,
there are a few points that need to be noted.
BELT ALIGNMENT
The WALKING BELT(10) must be in the center of the WALKING BOARD(9) to prevent it from rubbing
against the MOTOR COVER(11). If the belt rubs the MOTOR COVER(11),itwillbediculttokeepthe
belt moving and will eventually damage the edge of the belt. The treadmill has belt guides at the bottom of
the treadmill frame that move the belt toward the center of the treadmill. However, the REAR ROLLER(8)
must be properly aligned with the treadmill frame and FRONT ROLLER(7) if the belt is to remain centered
on the treadmill. The bolts in the rear of the treadmill (one on the left and the other on the right) adjust the
alignment of the REAR ROLLER(8) as well as the tension of the belt.
The belt will run to the side that has the loose rear bolt.
Hint:
BELT DRIFTING LEFT
Adjust by turning the left screw 1/4 turn CLOCKWISE and the right screw
1/4 turn COUNTERCLOCKWISE. Walk on the treadmill to check alignment.
Repeat if needed.
BELT DRIFTING RIGHT
Adjust by turning the left screw 1/4 turn COUNTERCLOCKWISE and the
right screw 1/4 turn CLOCKWISE. Walk on the treadmill to check alignment.
Repeat if needed.
NOTE:
When you believe the WALKING BELT(10) is centered, use the treadmill for three (3) minutes to verify the
WALKING BELT(10) won’t drift to one side or the other. If the WALKING BELT(10) continues to drift, the
oormaynotbelevel.Rotatethetreadmill90degreesormovethetreadmilltoanotherlocation.
BELT TENSION
The WALKING BELT(10) should be taut and not lying loosely on the treadmill WALKING BOARD(9). If
the belt is too loose, it will slip on the front roller and you will notice a jerky movement when you walk on
thetreadmill.Ifthebeltistootight,theedgesofthebeltwillbegintocurlandmoreeortwillberequiredto
move the belt. Excessive belt tension can also damage the bearings in the rollers. The bolts on the ends
of the MAIN FRAME(1) (one on the left and the other on the right) adjust the WALKING BELT(10) tension
as well as the REAR ROLLER(8) alignment.
BELT TOO LOOSE: Use the 6mm ALLEN WRENCH to tighten the bolts on the ends of the MAIN FRAME(1).
Tighten both bolts 1/4 turn clockwise at a time until the belt stops slipping on the FRONT ROLLER(7).
BELT TOO TIGHT : Use the 6mm ALLEN WRENCH to loosen the bolts on the ends of the MAIN FRAME(1).
Loosen both bolts 1/2 turn counterclockwise at a time until the belt begins to slip on the FRONT ROLLER(7).
Then use the procedure above to tighten the belt to the proper tension.
15
Visually check the REAR ROLLER(8) to make sure both the right side and the left side of
the REAR ROLLER(8) are the same distance from the back edge of the treadmill. Using
the 6mm ALLEN WRENCH, make adjustments by turning the bolts clockwise to tighten and
counterclockwise to loosen.
When doing the adjustment and checking whether the belt is in the center, you can power on the
treadmill and run it with speed 3 mph to check for 1 - 2 minutes.

STORAGE
The safety and integrity designed into the inStride Treadmill can only be maintained when the inStride
Treadmill is regularly examined for damage and wear. Special attention should be given to the following:

ROUND PLUG(22) from the HANDRAIL COVER(23). Use the
ALLEN WRENCH(6mm)(53) to tighten the FLAT SOCKET
HEAD BOLT(M10x1.45x30)(74) which is located on the inside
of the cover. The HANDRAIL(4) must be able to rotate, do not
overtighten the bolt. Press the ROUND PLUG(22) back into
the HANDRAIL COVER(23).
WALKING BELT AND BOARD LUBRICATION
If the WALKING BELT(10) does not move easily, or every 600
hours of use, lubricate the WALKING BOARD(9) with 100%
silicone lubricant. Lift one side of the WALKING BELT(10),
apply approximately 20 ml of lubricant to the center of the
WALKING BOARD(9). Start the treadmill at the lowest
speed to allow the lubricant to spread all over the WALKING
BOARD(9).

How you begin your exercise program depends on your physical condition. If you have been inactive for
several years or are severely overweight, start slowly and increase your workout time gradually. Increase
your workout intensity gradually by monitoring your heart rate while you exercise.
Initially you may only be able to exercise within your target zone for a few minutes; however, your aerobic
capacity will improve over the next six to eight weeks. It is important to pace yourself while you exercise
so you don't tire too quickly.
Measure your heart rate periodically during your workout by stopping the
exercise but continuing to move your legs or walk around. Place two or
threengersonyourwristandtakeasixsecondheartbeatcount.Multiply
theresultsbytentondyourheartrate.Forexample,ifyoursixsecond
heartbeat count is 14, your heart rate is 140 beats per minute. A six second
count is used because your heart rate will drop rapidly when you stop
exercising. Adjust the intensity of your exercise until your heart rate is at the
proper level.
wrist pulse
Remember to follow these essentials:
Have your doctor review your training and diet programs.
Begin your training program slowly with realistic goals that have been set by you and your physician.
Warm up before you exercise and cool down after you work out.
Take your pulse periodically during your workout and strive to stay within a range of 60% (lower
intensity) to 90% (higher intensity) of your maximum heart rate zone. Start at the lower intensity, and
builduptohigherintensityasyoubecomemoreaerobicallyt.
If you feel dizzy or lightheaded you should slow down or stop exercising.
To determine if you are working out at the correct intensity, use a heart rate monitor or use the table
below. For effective aerobic exercise, your heart rate should be maintained at a level between 60%
and 90% of your maximum heart rate. If just starting an exercise program, work out at the low end of
your target heart rate zone. As your aerobic capacity improves, gradually increase the intensity of your
workout by increasing your heart rate.
CONDITIONING GUIDELINES
Target Heart Rate Zone Estimated by Age*
* For cardiorespiratory training benefits, the American College of Sports Medicine recommends
working out within a heart rate range of 55% to 90% of maximum heart rate. To predict the
maximum heart rate, the following formula was used: 220 - Age = predicted maximum heart rate

WARM-UP and COOL-DOWN
Warm-Up
The purpose of warming up is to prepare your body for exercise and to minimize injuries.
Warm up for two to ve minutes before strength training or aerobic exercising. Perform activities that
raise your heart rate and warm the working muscles. Activities may include brisk walking, jogging,
jumping jacks, jump rope, and running in place.
Cool-Down
The purpose of cooling down is to return the body to its normal, or near normal, resting
state at the end of each exercise session. A proper cool-down slowly lowers your heart rate and allows
blood to return to the heart. Your cool down should be completed after each strength training session.
