I want the precision four column cutting machine to be used for a few more years and maintained diligently on a daily basis. Firstly, after use every day, clean up the waste materials, especially the debris on the workbench and cutting die, to prevent them from getting stuck in the machine. You can use a soft brush to sweep or blow with compressed air. Do not use hard objects to scrape, as it can easily scratch the countertop.

Secondly, regularly lubricate the guide post and slider, just like oiling a bicycle chain, to ensure smooth up and down sliding. If you hear a "squeaking" sound when the machine is running, it may be due to a lack of oil. Please replenish it as soon as possible.

The knife mold is a vulnerable part that will become dull over time, and the edges of the cut material will be rough. It is recommended to check the cutting die once a week and promptly polish or replace it if it becomes dull. In addition, the circuit part should be moisture-proof to prevent water from splashing into the control box. Regularly check whether the wires have broken skin to avoid leakage.

Finally, when not in use for a long time, it is better to remove the knife mold and apply some rust proof oil to prevent rusting. If the machine needs to be moved, do not forcefully push or pull it. First, loosen the fixing screws to avoid damaging the guide posts. Only when these small details are done well can the machine work steadily.
