CUTTING HEIGHT ADJUSTMENT
The standard cutting height is adjustable from
1-3/16" to 4-3/8" (3 to 11.1 cm). To raise the
cutting height, place more spacers (up to 4)
below the cutter disk. Spacers not used under
the cutter disk must be assembled above the
cutter disk. For example, if you place two
spacers under the cutter disk, the other two
spacers must be in place above the cutter
disk.
NOTE: There must always be at least one
spacer between the cutter disk and the height
guide.
