Why does fellowes paper shredder oil gum up?

Fellowes paper shredder oil can gum up due to a buildup of paper dust and debris that mixes with the oil, creating a sticky residue. Over time, if the oil is not applied regularly or in the right amount, it can also dry out and become less effective, leading to further gumming. Additionally, using the wrong type of oil or failing to clean the shredder regularly can exacerbate the problem. It's essential to use the recommended oil and to maintain the shredder for optimal performance.
