**Usage Tips:**
- When the drill bit is blocked during drilling, gently press down the drill bit tube with a guide needle to clear the blockage. Do not forcefully press down on the paper when the drill bit is blocked, as this may cause the drill bit to crack or break.
- Remove any glue, staples, paper clips, or other hard objects from the documents before drilling to prevent damage to the drill bit.
- Drill bits, washers, and rivets are consumables and are not covered by the warranty. Evaluate the lifespan of the drill bit based on the binding volume and replace it in a timely manner. Regularly sharpening the blade can extend the lifespan of the drill bit.
- Washers can be rotated and reused. Rotate the washer after each full circle of holes until it is no longer usable, then replace it.
