the treadmill electricity into the ground. Completely insert the plug into a standard socket for
proper use.
If the treadmill’s grounding conductor’s connection is improper, it will cause electric shock. If
you have any doubt about whether your product is grounded correctly or not, please contact a
professional to check and verify for you.
When plugging in the treadmill power cord, please plug it into a socket that has the same shape
as the plug itself. Do not use a plug adapter.

the treadmill is
running, the
controller detects
the electric current
is over 6A(unit to
measure electricity)
for more than 3
seconds.
Possible Causes: *Overloading the treadmill machine system
through prolonged use can lead to excessive electric current and
the treadmill will stop for your safety. *A part might be stuck
causing the motor to stop, adjust the treadmill and restart it.
*The motor may need to be replaced, check if there is a liquid or
burnt smell while the motor is running, if yes replace it. *The
treadmill monitor may need to be replaced, check if it has a
burnt smell, if yes replace the monitor. *The power supply
voltage may need to be changed, check the power supply voltage
if it does not match specifications adjust to the correct voltage
and test the treadmill again.

abnormal voltage
level or motor issue
has caused the motor
to not work properly
Possible Causes: The power supply voltage may be low. Check
if the power supply voltage is 50% lower than the normal
voltage of 110V, if it is, adjust it back to 110V and test the
treadmill again. *The controller may need to be replaced. Check
if the controller has a burnt smell, if yes, replace the controller.

5. Routine maintenance
Warning: Before cleaning or doing product maintenance, please ensure the treadmill power plug is
pulled out of the electric socket.
Cleaning: Thoroughly cleaning your treadmill will extend its usage life.
Remove dust periodically in order to keep the parts clean. Be sure to clean both sides of running
belt, this will reduce the accumulation of dust and dirt. Treadmill belts must be cleaned with a damp
soapy cloth. Do not use a dripping wet cloth. Please be sure to not wet the electrical components of
the treadmill including underneath the running belt to keep everything dry and functional.
Warning: Ensure that the power plug is disconnected before removing the motor cover. Clean the
motor at least once a year.
Running belt specialized lubricant
This electric treadmill’s running board and running belt have already been lubricated in the
manufacturing process. Friction between the running belt and running board heavily impacts how
long your treadmill will last and its performance, therefore regular application of the lubricant is
needed. Please check the board regularly to ensure it is properly lubricated. If the board’s surface is
damaged, please contact our customer service center. We recommend applying the lubricant
between the running belt and running board using the following schedule:
Light user (uses treadmill less than 3 hours a week): Apply lubrication once a month
Heavy user (uses treadmill more than 7 hours a week): Apply lubrication twice a month, at the
beginning of the month and halfway through the month.
1. For safety measures and to extend the life of your treadmill, it is recommended that if you use the
treadmill for 2 hours or more non-stop, to turn off the machine and let it rest for 10 minutes before
using again.
2. If the treadmill belt is too loose, you will experience skidding while running. If the belt is too
tight, it may reduce motor performance and increase friction between the roller and running belt
impacting your running experience. You can lift two sides of the running belt for 50-75mm when
the tightness is appropriate.
Running with adjusted alignment and tightness
In order to use your treadmill properly so it can function well, it is necessary for you to adjust the
running belt into the best position.
How to align the running belt
Put the treadmill flat on the ground
Make the treadmill run at a speed of about 3-5mph.
If the running belt is closer to the right, rotate the right adjusting bolt with a ½ turn
clockwise, then rotate the left adjusting bolt with a ½ turn counter-clockwise (Picture B)
If the running belt is closer to the left, rotate the left adjusting bolt with a ½ turn clockwise,
then rotate the right adjusting bolt with a ½ turn counter-clockwise (Picture A).
