After the machine has been used for a long time, the transmission belt of the mixing system may be stretched and needs to be adjusted. The phenomenon is that the belt slips. The machine stops suddenly after running for a while. The digital tube of the series of soft ice cream machines will display the word "NL" and beep at the same time. The device emits a long and regular intermittent sound. At this time, disconnect the power supply, remove the left side panel of the machine, and use a wrench to adjust the screw fixed under the motor (the specific situation varies slightly depending on the machine model, please call the after-sales phone for consultation) At this point, the machine is not malfunctioning. The machine must be shut down and powered off before adjusting the belt. After the belt is adjusted properly, the machine will return to normal.
