How to maintain A4 paper cutter

        The maintenance of the paper cutter is the key to how long it can last. According to the survey, the average life of the machine that is frequently maintained is higher than that of the machine that has not been maintained for several years. Therefore, it is very important to maintain the A4 paper cutter. The following is the daily maintenance method of A4 paper cutter.

　　 1. Maintain the hydraulic pressure properly. If the pressure is too high, the seal ring will burst, if it is too small, it will be delayed and weak.

　　 2. First of all, according to the different seasons, choose a suitable hydraulic oil machine, such as the use of No. 20 engine oil in winter to maintain its fluidity; in the summer use No. 30 engine oil to maintain its certain viscosity.

3. It is necessary to use talc or paraffin to coat the cutting platform and blade opening of the A4 paper cutter. If you do this, there will be two benefits: 1. Reduce the frictional resistance between the paper and the platform, and save effort. 2. Extend the cutting times of the blade. The cut edge is smooth and neat.

　　 4. Add lubricating oil in time. Fill the lubricating oil at the oil filling port of the A4 paper cutter before work to keep the machine lubricated and clean, and keep the machine in good working condition.
