CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
Important notice on the batteries for the Hitachi
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modi
fi
ed (such as
disassembly and replacement of cells or other internal
parts).
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.
1. Power tool
Symptom
Possible cause
Remedy
Tool doesn’t operate.
No remaining battery power
Charge the battery.
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.
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.
NOTE
Due to HITACHI’s continuing program of research and
development, the speci
fi
cations herein are subject to
change without prior notice.
