Symptom
The tool does not trim
Tool
well.
Possible cause
The blade has become dull.
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.
Remedy
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.
Consult your dealer or the Hitachi
Authorized Service Center. And
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.
