Tips: How to increase the life of paper puncher?

1. Correct operation
   Avoid overloading: Carefully read the instruction manual of the manual hole puncher to clarify the maximum paper thickness it can handle. Never put too many sheets of paper in at once for the sake of convenience. For example, if the hole puncher is marked with a maximum capacity of 30 sheets of regular A4 paper, do not attempt to insert 40 sheets. Otherwise, it is likely to cause problems such as deformation of the cutting tool and damage to the connecting rod of the hole puncher.
   Standardize the operation process: Align the papers neatly and place them steadily in the punching area to ensure the punching position is accurate. When pressing the handle of the hole puncher, maintain a uniform and moderate force. Avoid sudden excessive force, as this may cause excessive impact on the internal structure of the hole puncher and loosen the parts. Also, avoid intermittent force application to ensure a smooth punching process.
   
2. Daily maintenance
   Keep clean: After each use of the manual hole puncher, promptly clean the remaining paper scraps on its surface and inside. You can use a small soft brush to gently remove the debris from parts such as the cutting tool, card slot, and handle connection. If these paper scraps accumulate for a long time, they may hinder the normal opening and closing of the hole puncher and affect its performance.
   Regular lubrication: The moving parts of the hole puncher, such as the connecting shaft of the handle and the body, and the sliding track of the cutting tool, need to be lubricated regularly. Generally, apply an appropriate amount of lubricating oil (such as sewing machine oil) to these parts every 1 - 2 weeks, and then open and close the hole puncher several times to make the lubricating oil evenly distributed. This can effectively reduce the friction between parts and extend the service life of the hole puncher.
   
3. Cutting tool maintenance
   Replace worn-out cutting tools in a timely manner：Regularly check the condition of the cutting tool of the hole puncher. When the edges of the punched holes are no longer smooth and obvious burrs or incomplete holes appear, it indicates that the cutting tool has been worn. At this time, the cutting tool should be replaced in a timely manner. Otherwise, it will not only reduce the punching quality but also increase the force required for punching, further damaging the hole puncher.
   Proper storage of cutting tools：If the hole puncher is equipped with spare cutting tools, when not in use, the cutting tools should be properly stored. You can place the cutting tools in a special protective cover to avoid collisions between the cutting tools and prevent damage to the blade edges.
4. Storage environment
   Choose a dry and well-ventilated place, and avoid direct sunlight.
