In this article, we will explore common causes of this issue and provide helpful tips to overcome it.
One of the most common reasons for being unable to remove a circular saw blade is rust. Over time, moisture can cause the blade arbor and bolt to develop rust, making it difficult to loosen and remove the blade. In such cases, it is essential to apply penetrating oil to the arbor and bolt and let it sit for a few minutes to loosen the rust. Using a wrench or a blade removal tool, carefully try to loosen the bolt by turning it counterclockwise. If the rust is severe, you may need to repeat the process several times, ensuring that the oil penetrates deeply.
Overtightening the blade bolt can also make it challenging to remove the circular saw blade. When installing a new blade, it’s important to tighten the blade bolt firmly but not excessively. If the bolt is overtightened, it can create a strong grip on the blade, making it hard to remove. In such cases, using a blade removal tool or a properly sized wrench, apply steady pressure while turning the bolt counterclockwise to break the tight seal. If needed, you can use a rubber mallet to tap gently on the wrench or tool to provide additional force.
Incorrect blade installation can be another reason why you can’t remove the circular saw blade. If the blade is not installed properly, it may get stuck in the arbor, causing difficulty in removal. Before attempting to remove the blade, ensure that the saw is unplugged or the battery is disconnected for cordless models. Then, check if the blade is correctly aligned with the arbor and mounting flange. If it appears misaligned, try gently rotating the blade counterclockwise while applying slight pressure to disengage it from any stuck position. Once the blade is dislodged, you should be able to remove it by turning the bolt counterclockwise.
If you are still unable to remove the circular saw blade after trying these steps, it is recommended to seek professional assistance. A professional can provide further guidance and ensure that the blade removal is done safely and efficiently. Remember, always prioritize your safety when working with power tools, and never force or use excessive pressure when trying to remove a stuck blade.
