How to change the band saw blade on a band saw?
First, disconnect the machine from the mains, remove all stops and open the doors. All safety covers that could block the saw blade and the table insert in the work table are removed. The band guide is loosened and pushed back a little, if possible. The band saw blade is then released by loosening the handwheel for band tension. On some models, the saw can be released by a lever.
Now you can carefully remove the band saw blade from the rollers and unthread it from the saw blade guide and cover. Make sure that the band saw blade is not bent too much or even kinked in the process. Then thread the new band saw blade back in the opposite way and place it loosely on the upper and lower rollers. Sometimes the tension on the handwheel has to be loosened a little.
Place the new saw blade approximately centrally on the rollers. The saw teeth do not need to protrude over the rubber bands at the front, as is sometimes assumed. Now slightly pre-tension the band saw blade again by turning the hand wheel. The band tension depends on the width of the band saw blade. Wider band saw blades can be tensioned more than narrow ones.
