TROUBLESHOOTING
Use the inspections in the table below if the tool does not operate normally. If this does not remedy the problem, consult your
dealer or the Hitachi Authorized Service Center.
Symptom
Possible cause
Remedy
Charger The Charge lamp does not go
on.
The power plug is not connected to
an AC outlet.
Connect the power plug to an AC
outlet.
The battery is not properly
connected to the charger.
Insert the battery so that it is properly
seated in the charger.
The battery or charger electrodes
are soiled.
Use a cotton swab or other tool to
clean the electrodes.
The battery is extremely hot.
Allow the battery to properly cool
before charging.
The Charge lamp does not go
o
ff
after 4 hours of charging.
The battery or charger is faulty.
Disconnect the power plug and
consult your dealer or the Hitachi
Authorized Service Center.
Tool
Does not operate.
The battery has not been properly
installed.
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.
Foreign matter is lodged in the
blade.
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.
The tool has been used for heavy
work.
This is the e
ff
ect of a function that
protects the battery by turning o
ff
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.
The tool does not trim well.
The blade has become dull.
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 e
ff
orts fail to make the blade
sharper, the blade has reached the
end of its service life. Replace the
blade with a new one.
The blade stopped because it
was used to cut a branch whose
width exceeded the blade’s cutting
capacity.
NOTE
Work that will repeatedly cause
the blade to stop will eventually
damage the motor.
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.
