4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period
is not activated, the electric discharge might be low when
using them the fi rst and second time. This is a temporary
phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery. If
you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate, and
the battery life will be shortened. Leave the battery and
recharge it after it has cooled for a while.
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
injury.
1. Sharpening the blade (Fig. 10)
Move an iron fi le in the direction of the arrow for a rough
sharpening then use an oil stone to give the blade a good
fi nish.
(1) Use a fi ne iron fi le or one of intermediate coarseness.
(2) Coat the oil stone with machine oil (bicycle oil or the like).
(3) Use a whetstone to gently remove any burrs from the
back of the blade edge.
When to sharpen the blade
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.
NOTE
Do not use water for cleaning the blade to prevent rust or
other damage.
2. Lubricating the blade
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.
