I just recently bought a Harvey BS and never had a saw with a tensioner. I took a piece of cloth (about the size of a washcloth and covered the power switch and held it there with a magnet. I needed to move the cloth to the side to hit the switch. That was my way of remembering to set the tension. Then I realized I've owned a bandsaw for over 25 years and never detensioned it. The only time I touch it is to change the blade. Now the rag reminds me to turn on the dust collection. 🤪
