Maintenance
Proper maintenance is very important to ensure a
faultless and operational condition of the treadmill.
Improper maintenance can cause damage to the
treadmill or shorten the life of the product and
exceed the LIMITED WARRANTY coverage.
Important: Never use abrasives or solvents to
clean the treadmill. To prevent damage to the
computer, keep liquids away and keep it out of
direct sunlight.
All parts of the treadmill must be checked and
tightened regularly. Worn out parts must be
replaced immediately.
BELT ADJUSTMENT
You may need to adjust the running belt during the
first few weeks of use.All running belts are
properly set at the factory. It may stretch off the
center after use. Stretching is normal during the
break-in period.
ADJUSTING THE BELT TENSION
If the running belt feels as though it is “slipping” or
hesitating when you plant your foot during a run,
the tension on the running belt may have to be
increased.
TO INCREASE THE RUNNING BELT TENSION
STEP 1: Place 6#Allen wrench on the left belt
tension bolt. Turn the wrench clockwise 1/4 turn to
draw the rear roller and increase the belt tension.
STEP 2: Repeat STEP 1 for the right belt tension
bolt. You must be sure to turn both bolts the same
number of turns, so the rear roller will stay square
relative to the frame.
Repeat STEP 1 and STEP 2 until the slipping
is eliminated.
Be careful not to tighten the running belt
tension too much as you can create excessive
pressure on the front and rear roller bearings.
An excessively tightened running belt may
damage the roller bearings that would result in
bearing noise from the front and rear rollers.
TO DECREASE THE TENSION ON THE
RUNNING BELT, TURN BOTH BOLTS
COUNTER-CLOCKWISE THE SAME NUMBER
OF TURNS.
CENTERING THE RUNNING BELT
When you run, you may push off harder with one
foot than with the other. The severity of the
deflection depends on the amount of force that
one foot exerts in the relation to the other. This
deflection can cause the belt to move off-center.
This deflection is normal and the running belt will
center when nobody is on the running belt. If the
running belt remains consistently off-center, you
will need to center the running belt manually.
Are view of all warning labels that relate to
correct and safe maintenance of the
treadmill and how to obtain replacements.
The safety and integrity designed into the machine
can only be maintained when the treadmill is
regularly examined for damage and repaired.
It is the sole responsibility of the user/owner or
facility operator to ensure that regular maintenance
is performed.
Only manufacturer-supplied or approved
components shall be used to maintain
and repair the treadmill.
The maintenance instructions shall call the
reader’s attention to these facts.

16
CENTERING THE RUNNING BELT
MOTER BELT TENSION ADJUSTMENT
During your workout, if you find the running belt is not running smoothly, it could mean that the motor belt
has lost some tension, please follow the below steps to adjust the motor belt tension:
1. Turn the motor belt adjustment bolt using an M8 Allen wrench 1/4 turn in clockwise direction.
2. Re-Start the treadmill and run on the treadmill; if the running belt is still not working properly, repeat
above step.
3. Please do not make the motor belt too tight; if the belt is over tightened, it will cause the treadmill over
loading and reduce the motor life.
1. Start the treadmill without anyone on the running belt, press “Speed+” button until speed reaches
4mile/h.
2. Observe whether the running belt is toward the right or left side of the deck.
a) If toward the left side of the deck, using 6# Allen Wrench, turn the left adjustment bolt
clockwise 1/4 turn and let the running belt find its new position; if it’s still moving toward left side,
turn the bolt another 1/4 turn.
b) If toward the right side of the deck, using 6# Allen Wrench, turn the right adjustment bolt
clockwise 1/4 turn and let the running belt will find its new position; if it’s still moving toward right
side, turn the bolt further for 1/4 turn.
c) If the belt is still not centered, repeat the above steps until the running belt is centered.
3. After the belt is centered, increase the speed to 8mile/h and verify that it is running smoothly.
Repeat the above steps if it is necessary. If the above procedure is unsuccessful in resolving the
off-center issue, you may need to increase the belt tension.

17
DECK LUBRICATION
The treadmill is pre-lubricated. However, it is
recommended to check the lubrication of the
treadmill regularly, to ensure an optimal operation
of the treadmill.
After every 2 months of operation, lift the sides of
the treadmill and feel the surface of the belt, as far
as possible. If traces of silicon spray are found,
lubrication is not necessary. In case of a dry
surface, refer to the instructions below.
Only use 100% silicon oil to lubricate your
treadmill deck.
To apply lubricant on the belt
Position the belt so that the seam is located in
the middle of the plate.
Lift the belt at one side and hold the spray
valve at a distance of approximately 15cm to
the front end of belt and plate.Then spray from
front to the end. Repeat this process on the
other side of the belt. Spray each side for
about 4 seconds.
Wait 1 minute to let the silicon spray spread,
before starting the machine.
CLEANING
Regular cleaning of the belt ensures a long
product life.
Warning: The treadmill must be turned off to
avoid electric shocks. The power cord must be
pulled out of the socket, before starting the
cleaning or maintenance.
Caution: Do not use any abrasives or
solvents. To avoid damage to the computer,
keep any liquids away. Do not expose the
computer to direct sunlight.
After each training: Wipe the console and
other surfaces with a clean soft and damp
cloth to remove sweat residues.
Weekly: To make cleaning easier, it is
recommended to use a mat under the
treadmill. Shoes can leave dirt on the belt that
can fall beneath the treadmill. Clean the mat
under the treadmill once a week.
STORAGE
Store you treadmill in a clean and dry environment.
Ensure the master power switch is off and is
un-plugged from the electrical wall outlet.

EXERCISE INSTRUCTIONS
Each workout should include the following three parts:
1. The Warm Up Phase
This stage helps get the blood flowing around the body and the muscles working properly. It will also
reduce the risk of cramp and muscle injury. It is advisable to do a few stretching exercises as shown
below. Each stretch should be held for approximately 30 seconds, do not force or jerk your muscles
into a stretch - if it hurts, STOP.
2. The Exercise Phase
This is the stage where you put the effort in. After regular use, the muscles in your legs will become more flexible.
Work to your targeted heart rate but it is very important to maintain a steady tempo throughout. The rate of work
should be sufficient to raise your heartbeat into the target zone shown on the graph below.
This stage should last for a minimum of 12 minutes though most people start at about 15-20 minutes
