the battery cartridge is removed before attempt-
ing to perform inspection or maintenance.

Cleaning the tool

Clean out the tool by wiping off dust with a dry or soap-
dipped rag.
CAUTION:
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.

Blade maintenance

Smear the blade before and once per hour during oper-
ation using machine oil or the like.
NOTE:
• Before smearing the blade, remove the chip
receiver.
After operation, remove dust from both sides of the
blade with wired brush, wipe it off with a rag and then
apply enough low-viscosity oil, such as machine oil etc.
and spray-type lubricating oil.
CAUTION:
• Do not wash the blades in water. Failure to do
so may 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
the battery cartridge is removed.
• When replacing the shear blade, always wear
gloves without removing blade cover so that

blade. Failure to do so may cause personal
injury.
