To maintain stable operation of Songri vacuum packaging machines, routine maintenance is paramount. Firstly, promptly clean residual debris and oil stains from the vacuum chamber after each use to prevent impurities from clogging the suction port and compromising vacuum performance. Secondly, regularly apply silicone oil to the sealing strips to preserve their elasticity and prevent poor sealing due to ageing.

For the vacuum pump of the Songri machine, it is advisable to replace the vacuum pump oil every three months to ensure efficient extraction. The electrical components must be protected from moisture exposure. If the equipment remains unused for extended periods, disconnect the power supply and implement dust-proof measures. Furthermore, should any malfunction occur, contact the professional after-sales team for repairs; never attempt disassembly yourself.
