HOW TO USE
General cleaning will help prolong the life and performance of your treadmill. Keep the unit clean and
maintained by dusting the components on a regular basis. Clean both sides of the running belt to prevent
dust from accumulating underneath the belt. Keep your running shoes clean so that dirt from your shoes
does not wear out the running board and belt. Clean the surface of the running belt with a clean damp cloth.
• To make the cleaning easier it is recommended to use a mat for the treadmill. Shoes can leave dirt on the
striding belt that can fall beneath the treadmill. Clean the mat under the treadmill once a week.
• To better maintain the treadmill and prolong its life it is suggested that the machine be powered o󰀨 for 10
minutes every 2 hours and fully powered o󰀨 whenever not in use.
• A loose Running Belt will result in the runner sliding o󰀨 when running, while too tight of a Running Belt will
result in decrease to the motors performance and also create more friction between the roller and running
belts. The most suitable tightness for the belts is pulled out 50-75mm from the Running Board.
MAINTENANCE AND CARE
1. Turn the power on , keep the treadmill spread out at its lowest position and check its function if normal.
2. Clip the safety key cord with your clothes.

supposed to catch handle bar at the same time and feet step to the running belt successively to start
running. Running as quickly as running belt soon.
4. After several minutes, you can speed up by pressing +key or slow down by -key meanwhile holding the
handle bar.
5. When running ,press speed value,you can enter into the xed speed you want .
6. Pressing STOP key to make the motor stop.
PRE-SETTING USE

• Press START key to get started in your selected mode.
• You can press +or - to change the speed or STOP key to make it stop.
HRC TESTING
After the treadmill is powered on, hold your hands on the metal pulse sensors, then you can see HRC value
on the display window.
NOTE: When safety key pull out ,the treadmill will stop immediately. And thecomputer can not work,
the window shows “__”.

MAINTENANCE AND CARE
CENTERING THE RUNNING BELT:
Place the treadmill on level ground and set it at 6-8kph to check if the Running Belt drifts.
2. If the Running Belt moves to the left,
turn the adjusting bolts on the left side ¼of
a turn clockwise,then turn the right
adjustment bolt ¼ turn counter-clockwise. If
the belt does not move, repeat this step until
it centers. Refer to figure B.
3. Over time the Running Belt will loosen.
To tighten the belt turn the Left & Right side
adjustment bolts one full turn clockwise,
check the tension of the belt. Continue this
process until belt is at the correct tension.
Make sure to adjust both sides equally to
ensure correct belt alignment. Refer to
figure C.
1. If the Running Belt moves to the right,
turn the adjusting bolt on the right side ¼
turn clockwise, then turn the left adjustment
bolt ¼ turn counter-clockwise. If the belt
does not move,repeat this step until it
centers. Refer to figure A.

LUBRICATING THE TREADMILL
IMPORTANT NOTE:
The treadmill is factory-lubricated. However, it is recommended to check the lubrication of the treadmill regu-
larly, to ensure an optimal operation of the treadmill.
RUNNING BELTS & TREADMILL LUBRICANT:
Lubricating the running board and running belt is essential as the friction between the two a󰀨ects the life
span and function of the treadmill, therefore it is suggested that the running board and belt be inspected
regularly.
Always unplug the treadmill from the electrical outlet before cleaning, lubricating or repairing the unit.
HOW TO LUBRICATE:
1. Raise the belt up on one side and apply lubricant to the running deck. Use a rag to thoroughly wipe the
lubricant over the running deck. Repeat this process for the other side.
2. The moving parts should turn freely and quietly. Abnormality of moving parts will a󰀨ect the safety of the
equipment. Inspect and tighten bolts regularly.
3. To better maintain the treadmill and prolong its lifespan, it is suggested that maintenance be done on a
regular basis.
!
WARNING!
The following time table is recommended:
Light user less than 3 hours/week every six months
Medium user 3-5 hours/week every three months
Heavy user more than 5 hours/week every two months
STORAGE
Store you treadmill in a clean and dry environment. Ensure the master power switch is o󰀨 and is un-plugged
from the electrical wall outlet.

CONSOLE
Item trouble Maintenance
E1
Communication
abnormal:The
communication
between the
controller and the
electronic watch is
abnormal after
power is applied.
Broken controller couldn’t working. Console display
fault code and the buzzer sounded 3 times.
Reason: the poor communication between controller
and console. Checking each connection of
communication wire between console and controller.
Make sure each core is completely inserted. Check
the connection wire, if it was broken, change it.
E3
The motor line is not
connected properly
The treadmill stop working and enter a fault state when
the buzzer sounded 9 times. The console display fault
code while the rest areas do not display anything. If
console discovery normal state and enter standby state
after treadmill stop working, the treadmill can restart.
Reason: make sure the well connection of the motor
wire and connect the wire again. If the controller has
peculiar smell, replace the controller.
No signal of speed
sensor: a voltage from
controller is output to
the DC motor. The
motor speed feedback is
not continuously
received for more than 3
seconds.
The treadmill stop working and enter a fault state when
the buzzer sounded 9 times. The console display fault
code while the rest areas do not display anything. After
maintaining the fault state for about 10 seconds, enter
the standby state and restart the machine.
Reason: no speed sensor signal is detected for 3
consecutive seconds, check whether the sensor plug is
not plugged in or damaged, plug it in or replace the
sensor.
E4
Ascending by self
learning Check whether the induction line of the lifting motor is
plugged in properly and plug the connector again to
make it reliable. Check whether the AC line of the
lifting motor is plugged correctly, and the AC line of
the lifting motor is correctly numbered with the mark on
the controller. Check whether the connecting wire of the
motor is damaged or open, replace the connecting wire
or lift the motor; After checking all, press the learning
key on the control to learn again.
E5
Over current
protection ˖under the
running state, the down
control continuously
detects that the DC
motor current is greater
than the rated current
+6A for more than 3
seconds.
The treadmill stop working and enter a fault state when
the buzzer sounded 9 times. The console display fault
code while the rest areas do not display anything. After
maintaining the fault state for about 10 seconds, enter
the standby state and restart the machine.
Reason: over - rated load leads to over-current and
self-protection of the system, or a certain part of the
treadmill is stuck, resulting in motor failure, over-load
and over-current and self-protection of the system.
Adjust the treadmill and restart it. Check whether the
motor has over-current sound or burnt smell when
running, and replace the motor; Or check whether the
controller has burnt smell and replace the controller; Or
check whether the power supply voltage specification is
inconsistent or low, and retest with the correct voltage
specification.
E6
Explosion - proof
protection: abnormal
power supply voltage or
abnormal motor will
cause damage to the
drive motor circuit.
The treadmill stop working and enter a fault state when
the buzzer sounded 9 times. The console display fault
code while the rest areas do not display anything. After
maintaining the fault state for about 10 seconds, enter
the standby state and restart the machine.
Reasons: check whether the power supply voltage is
lower than 50% of the normal voltage, please retest
with the correct voltage specification; Check whether
the controller has peculiar smell and replace the
controller; Check whether the motor line is connected
properly and reconnect the motor line.
