Install the sleeve and tighten the three screws after
inserting the center blade, side blade L & R into the
cutting head. In this process, the screw heads should be
protruding 2 - 3 mm (1/16"-1/8") from the cutting head
surface.
If you will tighten the screws excessively, the cutting
head cannot be installed to the tool.
