enough low-viscosity oil, such as machine oil etc. and
spray-type lubricating oil.

cause rust or damage on the tool.
Removing or installing shear blade
CAUTION:
• Before removing or installing shear blade, always be
sure that the tool is switched off and unplugged.
• When replacing the shear blade, always wear gloves
without removing blade cover so that hands and face

may cause personal injury.

• Do not wipe off grease from the gear and crank. Failure
to do so may cause damage to the tool.
• For specific way of removing and installing shear
blades refer to the reverse of a package for accessory
shear blades.

CAUTION:
• Return the gear to the original position in such a
manner as it was installed if it should be taken away by

Installing the shear blade
Prepare 4 removed screws (For under cover), 2 screws
(For shear blade), gear housing cover, 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. (Fig. 26)
Overlap the oval hole in the upper blade with that in the
lower one. (Fig. 27)
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. (Fig. 28)
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
