(2) Regarding the temperatures and charging time of the rechargeable battery
The temperatures and charging time will become as shown in Table 2.

NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
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.
PRIOR TO OPERATION
WARNING
Before use, check the following. 1 to 3 should be
checked before insert the battery.
1. Confi rm that the vacuum switch is OFF. (Fig. 3)
If, without knowing that the vacuum switch is ON, the
battery is inserted, the appliance will start suddenly,
causing unexpected accidents. The vacuum switch will
be turned on by pushing "ON" and it will be turned off by
returning it to "OFF". Be sure to check that the vacuum
switch is OFF.
2. Order of use for batteries
When two batteries are installed, the battery with the
least remaining power is used fi rst until it is empty.
Once empty, use is automatically switched over to the
other battery.
Use is still possible with a single installed battery.
NOTE
When there is no more remaining power in a battery,
immediately recharge the battery for convenient use
later.
3. Check the fi lter
Referring to "3. Filter installation/confi rmation" in
"HOW TO USE" the fi lter should be correctly attached.
4. Inserting the battery (Fig. 4)
As you pull on the clamp lever, open the battery guard.
Next, match the battery with the unit's groove and
fi rmly press the battery in until you hear a click.
