Connect the power plug to an AC

Insert the battery so that it is
properly seated in the charger.
Use a cotton swab or other tool to
clean the electrodes.
Allow the battery to properly cool
before charging.
Disconnect the power plug and
consult your dealer or the Hitachi
Authorized Service Center.
Remove the storage battery from the
battery compartment in the tool and
check for foreign matter. Also check
the battery electrodes for soiling.
Make sure that the battery is pressed
in until it clicks into place.
If the blade does not move but the
motor is turning, the blade has
probably been incorrectly installed.
Make sure that the crank cam has
been installed.
When there is foreign matter in the
blade, remove the battery and use
a pair of tongs or similar tool to
remove it.
Take great care since the tool may
start operating when the foreign
matter has been removed.
Sap or rust may also prevent the
blade from operating. Use a wire
brush or similar tool to remove sap
or rust.
This is the effect of a function that
protects the battery by turning off
the motor when the tool is exposed
to an excessive load. Release the
switch and remove what caused
the excessive load and pull back
the switch to resume work.
Use a wire brush or other tool to
remove sap and rust and use a file
or whetstone to sharpen the blade.
If these efforts fail to make the
blade sharper, the blade has
reached the end of its service life.
Replace the blade with a new one.
