CAUTION
○ If the battery is charged while it is heated because
it has been left for a long time in a location subject to
direct sunlight or because the battery has just been
used, the charge indicator lamp of the charger lights for
0.3 seconds, does not light for 0.3 seconds (off for 0.3
seconds). In such a case, fi rst let the battery cool, then
start charging.
○ When the charge indicator lamp fl ickers (at 0.2-second
intervals), check for and take out any foreign objects in
the charger's battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.
○ Since the built-in micro computer takes about
3 seconds to confi rm that the battery being charged with
UC18YSL3 is taken out, wait for a minimum of 3 seconds
before reinserting it to continue charging. If the battery
is reinserted within 3 seconds, the battery may not be
properly charged.

MAINTENANCE AND INSPECTION
WARNING
○ Be sure to turn the tool off and remove the battery
from the tool before making inspections or carrying out
maintenance.
○ Do not disassemble to blade. Failure to heed this
warning may result in injury.
○ Use gloves, or cloth to protect your hands when handling
the blade. Failure to heed this warning may result in

Move an iron fi le in the direction of the arrow for a rough

fi nish.
back of the blade edge.
While this will vary the type of trees that are trimmed and
how often it is used, it is a good idea to sharpen the blade
about once a year to maintain a sharp edge.
Do not use water for cleaning the blade to prevent rust or
other damage.
During trimming, sap adhering to the blade edge will
increase load and wear down the battery more rapidly.
Use machine oil (or bicycle oil or the like) to lubricate the
blade and wipe the blade with a cloth. To prevent the
blade from rusting, be sure to lubricate the blade after
use and when it will not be used for an extended period
of time before placing it in the blade case.
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
When the hedge trimmer is stained, wipe with a soft dry
cloth or a cloth moistened with soapy water. Do not use
chloric solvents, gasoline or paint thinner, for they melt
plastics.
Remove the battery and attach the blade case to the
blade before carrying this tool.
If you carry it without the blade case, the blade may
come in contact with your body, causing injury.
Store the hedge trimmer in a place in which the
temperature is less than 40°C and out of reach of
children.
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
