Remedy
Connect the power plug to an AC
outlet.
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.
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 eff ect 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 fi le
or whetstone to sharpen the blade.
If these eff orts fail to make the blade
sharper, the blade has reached the
end of its service life. Replace the
blade with a new one.
Some garden trees have wood that
is very hard and may be beyond the
capacity of the tool even if it is of a
width that is within normal capacity.
Use a pair of pruning shear to remove
thick branches before starting work.
An oblique cut may also exceed the
capacity of the tool since the length of
the cut increases. Be sure to trim thick
branches at right angles.
