The spiral cutter block has four rows of square cutters running
around its circumference. There is a blade machined to each
side of the square cutter allowing the cutter to be rotated to a
clean sharp edge if one side has been damaged or has become
blunt, see fig 14A.
The square cutter has an embossed position marker to one
of its four corners, once this mark has gone round one fall
rotatation it is time to replace the square cutter.
To rotate the cutter, loosen the Torx head screw and rotate
until the new edge is in alignment with the other cutters.
Re-tighten the Torx head screw to lock the cutter in place.
WARNING! BE VERY CAREFUL WHEN TURNING THE
CUTTERS AS THE BLADES ARE EXTREMELY SHARP.
DO NOT OVERTIGHTEN TO AVOID THE SCREW HEAD
FROM GETTING DAMAGED!
