MAINTENANCE

17
Warning: be sure to unplug the electric treadmill before cleaning or maintaining the product.
Cleaning: comprehensive cleaning will extend the life of the electric treadmill.
Remove dust regularly to keep parts clean. Be sure to clean the exposed areas on both sides of the running belt,
which will reduce the accumulation of impurities under the running belt. Make sure your running shoes are clean
and don't wear out the running board and belt by carrying foreign bodies under the running belt. The surface of
the running belt must be swabbed with a wet soapy cloth. Be careful not to splash water on the electrical
components and under the running belt.
Warning: be sure to unplug the power supply of the electric treadmill before moving the motor cover. Open the
motor cover at least once a year to clean the motor dust belt and special lubricating oil for electric running
The running board and running belt of this electric treadmill have been pre-lubricated. The friction force between
the running belt and the running plate has a great impact on the service life and performance of the electric
treadmill, so it is necessary to apply lubricating oil regularly.
We suggest that the board be inspected regularly. If the surface is damaged, please contact our customer service
center.
We suggest lubricating the running belt and running board
of the electric treadmill according to the following
schedule:
Lightweight users (use less than 3 hours per week) once a
year;
Middleweight users (3-5 hours per week) once every 6
months;
Heavy users (over 5 hours per week) once every 3
months.

18
BELT ADJUSTMENT：
