stop. Adjust the treadmill and restart
it. Check if there is liquid or burnt
smell while the motor is running, if
yes, replace the motor; check if the

replace the controller; check the
power supply voltage, if it does not
match the specifications, change into
correct voltage and test the machine
again.
