Also, check for any foreign objects on the wooden part of the pencil. 3. **Insert the Pencil Correctly**: Insert one end of the pencil into the slot of the pencil sharpener. Make sure the pencil is inserted straight to ensure smooth and steady cutting. 4. **Turn On and Off**: When you are ready to start sharpening, gently press or rotate the switch according to the instructions of the pencil sharpener. While sharpening, maintain appropriate force and speed to prevent excessive force from damaging the pencil or causing the machine to jam. 5. **Rotate and Remove**: When you need to remove the sharpened pencil, hold it and rotate it out of the pencil sharpener. During this process, ensure your hands do not touch the rotating blade. 6. **Cleaning and Maintenance**: After each use of the pencil sharpener, promptly clean any wood chips and pencil fragments inside. This ensures smooth operation and prolongs the lifespan of the pencil sharpener. Also, regularly check if the blade needs to be replaced. II.
