Maintenance of A4 paper cutter is the key to its service life. According to the survey, the average life of the machine which is often maintained is several years longer than that of the machine which is not maintained. Therefore, it is very important to maintain the A4 paper cutter. The following is about the daily maintenance of A4 paper cutter.
1. Keep the hydraulic pressure properly. If the pressure is too high, the sealing ring will burst. If the pressure is too small, it will be sluggish and weak.
2. First of all, according to the different seasons, choose the appropriate hydraulic oil machine, such as 20 oil in winter to maintain its fluidity; 30 oil in summer to maintain its viscosity.
3. Talc powder or paraffin must be applied to the cutting platform and blade edge of A4 paper cutter. There are two advantages if this is done. One is to reduce the friction resistance between paper and the platform and save labor in operation. The other is to prolong the cutting times of the blade and make the cutting edge smooth and tidy.
4. Timely lubricating oil should be injected into the oil injection port of A4 paper cutter before working, so as to keep the machine lubricated and clean and keep the machine in good working condition.
