GROUNDING METHODS
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.
DANGER – Improper connection of the equipment-grounding conductor can result in a risk of electric
shock. Check with a qualified electrician or serviceman if you are in doubt as to whether the product is
properly grounded. Do not modify the plug provided with the product – if it will not fit the outlet, have a
proper outlet installed by a qualified electrician.
This product is for use on a nominal 110-volt circuit and has a grounding plug that looks like the plug
illustrated in sketch A in following figure. Make that the product is connected to an outlet having the same
configuration as the plug. No adapter should be used with this product.

WARM UP STAGE
Before exercise, it is better Warm muscles stretch more easily, so the first
of 5 ~ 10 minutes to warm up. Then in accordance with the following
methods to stop and do stretching exercises - do five times, each leg
every time 10 seconds or more time to do it again after the end of the
exercise.
1. Down the stretch: knees slightly curved, the body bent forward slowly,
so that the back and shoulders relaxed, hands try to touch your toes.
Maintain 10 to 15 seconds, and then relax. Repeat three times to do
(see Figure l).
2. Hamstring stretch: sitting on the clean seat, put one leg straight.
Inward close to the other leg to make it close to the inside leg straight.
Hands try to touch the toes. Maintain 10 to 15 seconds, and then relax.
Repeat for each leg do three times (see Figure 2).
3. Legs and feet tendon stretch: two on the Rotary wall or tree stand, one
foot in the post. Keep legs straight and heel to tilt the direction of the
wall or tree. Maintain 10 to 15 seconds, and then relax. Repeat for
each leg do three times (see Figure 3).
4. Quadricones stretch: the left hand wall or table Cu master balance,
and then stretched his right hand back to seize the right foot to the
buttocks with slowly pull until you feel the front thigh muscles tense.
Maintain 10 to 15 seconds, then relax. Repeat for each leg to do three
times (see Figure 4).

EXERCISE INSTRUCTIONS
Warm up stage：
If you are over 35 years old, or not very healthy, also it’s your first time exercise, please consult with your
doctor or professional person.
Before you use the motorized treadmill, please learn how to control the machine, know well how to start,
stop, adjust the speed and so on; don’t stand on the machine at this time. After that, you can use the
machine. Stand on anti-slip pad both sides and handle the handle bar with your both hands. Keep the
machine at the low speed about 1.0~2.0MPH, then test the running machine by one foot, after get used to
the speed, then you can run on the machine and you can add the speed between 2MPH and 4MPH. Keep
the speed about 10 minutes, then stop the machine.
Exercise stage：
Learn how to adjust the speed and incline before using. Walk about 0.62M at stable velocity and write down
the time, it will take you about 15-25 minutes. If walk at 4MPH, it will take you about 12 minutes in 0.62M. If
you feel comfortable at the stable velocity, you can add the speed and incline, after 30 Minutes, you can
have good exercise. At this stage, you cannot add the speed or incline too much at one time, it can keep
you feel comfortable.
Exercise intensity：
Warm up at the speed 4MPH in 2 minutes, then add the speed to 4.0MPH and keep walking in 2 Minutes,
then add to 5MPH and walk in 2 minutes. After that, add up 0.1MPHin each 2 minutes, until rapid breath but
not feel comfortable
Calorie burning---the best effective way
Warm-up for 5mints by the velocity:3.5-4MPH, then slowly increase the speed by 0.1MPH/2minutes, until
up to the stable speed which you feel is comfortable for 45 minutes. For improving the intensity of
movement, you can maintain the speed during 1H of TV program, then increase the speed by 0.1MPH
each advertisement interval time, after that return to the original speed . You can acquaint the best
efficiency of workout for calorie burning during the advertisement time and subsequent heart frequency
increasing time. Finally, you should slow down the speed step by step for 4 minutes.
Exercise frequency：
The cycle time: 3-5times/Week, 15-60minutes/Times. Make up the schedule of workout scientific, not only
for your hobby.
You can control the running intensity through adjusting the velocity and incline of treadmill. We suggest that
you don’t set the incline at first; improve the incline is the effective way to strengthen the exercise’s
intensity.
Consult with your physician or health professional before starting your workout. The professional
people can help you make up the suitable exercise time-chart according to your age and health
condition; determine the velocity of movement, the intensity of exercise. Please stop at once, if you
feel chest tightness, chest pain, irregular heartbeat, breath difficulty, dizziness or other discomfort
during exercise. You should consult with your physician or health professional as keep going. You
can choose the normal walking speed or the jogging speed, if you always take workout with
treadmill. If you don’t have enough experiences or confirm the testing velocity, you can follow the
instruction:

9
Speed 0.5-2.0MPH warm up
Speed 2.5-3.0MPH less movement and workout
Speed 3.5-4.0MPH normal walking
Speed 4.5-5.0MPH fast walking
Speed 5.5-6.0MPH Jogging
Speed 6.0-7.5MPH intermediate speed walking
Attention: For walker, it is better to keep the speed at ≤4MPH. For runner, it is better to keep the speed at
≥5MPH
MAINTANCE INSTRUCTION
WARNING: Always unplug the treadmill before cleaning or maintance.
General cleaning will greatly prolong the treadmill.
Keep treadmill clean by dusting regularly. Be sure to clean the exposed part of the deck on either side of
the walking belt and also the side rails. Keep the running shoes clean to avoid foreign material underneath
the walking belt.
WARNING: Always unplug the treadmill before removing motor cover.
Make sure to removing the motor cover and clean the motor one time per year.
Running belt and deck lubrication oil
This treadmill is equipped with a pre-lubricated, low maintenance deck system. The belt/ deck friction may
play a major role in the function and life of your treadmill, thus requiring periodic lubrication. We
recommend a periodic inspection of the deck. You need contact with our service center if you find the
damage of the deck.
We recommend lubrication of the deck according to the following timetable:
Light user (less than 3 hours/ week) - Annually
Medium user (3-5 hours/ week) - Every six months
Heavy user (more than 5 hours/ week) - every three months
We recommend that you buy the lubrication from our distributor or directly from us.
WARNING: Any repair needs the professional technician.

BELT ADJUSTMENT
We suggest that you should cut off the power for 10 minutes after keep running 1.5hours to maintain the
treadmill.
The belt would slip if too loose during using；if the belt is too tight, it would affect the performance of motor
and increase the abrasion of roller and belt. The belt can be lift away from the deck for around 50 — 75mm
if the degree of tightness is just well.
Center the running belt
1. Place treadmill on a level surface. Run Treadmill at
approximately 3.5-4.5MPH, checking the running
condition. If the belt has drifted to the right, pull out
of the save clock and switch, and turn the right
adjusting bolt 1/4 clockwise, then start running to
see if centered or not. Keep adjusting until
centering the belt. PICTURE – A
2. If the belt has drifted to the left ,pull out of the safety
clock and switch, turn the left adjusting bolt 1/4 turn
clockwise, then start running to see if centered or
not. Keep adjusting until centering the belt.
