Installing the shear blades
Prepare 4 removed screws (For under cover), 2 screws
(For shear blade), plate, under cover, and new shear
blades.
Adjust the crank position as shown in the figure. At
this time, apply some grease provided with new shear
blades to the periphery of the crank.

Take out the blade cover from the old shear blades and
fit it onto the new ones for easy handling during the
replacement of blades.
Place the new shear blades on the tool so that the oval
holes in the shear blades fit onto the crank. Overlap the
holes in the shear blades with the screw holes in the
tool and then secure them with two screws.
