Rotating or replacing blades
Both the upper and lower blades have four cutting
edges on each side (the front and back). When the
cutting edge becomes dull, rotate both the upper and
the lower blades 90° to expose new cutting edges.
When all eight edges are dull on both the upper and
lower blades, replace both blades with new ones. Each
time blades are rotated or replaced, proceed as follows.
► 1. Hex wrench 2. Lower blade 3. Upper blade secur-
ing bolt 4. Upper blade
Remove the blade securing bolts with the hex wrench
provided and then rotate or replace the blades.

After securing the upper blade, be sure that there is no
gap left between the upper blade and the beveled sur-
face of the blade holder.

3. Upper blade
Then install the lower blade like the upper blade while
adjusting the clearance between the upper blade and
lower blades. When performing this adjustment, the
upper blade should be in the lowered position.
► 1. Lower blade positioning bolt 2. Hex nut
3. Thickness gauge
First, semi- tighten the lower blade securing bolt, then
insert the thickness gauge for the desired clearance.
The cutting thickness is indicated on the thickness
gauge so the combinations shown in the table below
should be used. Work the lower blade positioning bolt
on the yoke until the clearance is such that the thick-
ness gauge moves only with some difficulty. Then firmly
tighten the lower blade securing bolt. Finally, tighten the
hex nut to secure the lower blade positioning bolt.
