General Information: How do I set the tension?

Screw the tension nut down by hand until it stops. Using the marker on the tension nut as a guide, slacken the tension nut back off by 1 1/2 turns to set the tension. This standard method of tensioning can be applied to all lister clippers. In the below images, the "Marker" on the tension nut.
