Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop appliance operation and charge the
battery cartridge when you notice less appliance
power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room
temperature at 10 °C - 40 °C (50 °F - 104 °F). Let a
hot battery cartridge cool down before charging it.
4. Charge the battery cartridge once in every six
months if you do not use it for a long period of
time.
PREPARATION
CAUTION:
• Always be sure that the appliance is switched off and
the battery cartridge is removed before adjusting or
checking function on the appliance.
Installing or removing battery cartridge
(Fig. 1)
CAUTION:
• Always switch off the appliance before installing or
removing of the battery cartridge.
• Hold the appliance and the battery cartridge firmly
when installing or removing battery cartridge. Failure to
hold the appliance and the battery cartridge firmly may
cause them to slip off your hands and result in damage
to the appliance and battery cartridge and a personal
injury.
• Take care not to trap finger(s) between cleaner and
battery as shown in diagram when loading battery.
Trapping finger(s) may cause injury.
To remove the battery cartridge, slide it from the appliance
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip it
into place. Insert it all the way until it locks in place with a
little click. If you can see the red indicator on the upper
side of the button, it is not locked completely.
CAUTION:
• Always install the battery cartridge fully until the red
indicator cannot be seen. If not, it may accidentally fall
8
out of the appliance, causing injury to you or someone
around you.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being inserted
correctly.
Indicating the remaining battery capacity

(Only for battery cartridges with "B" at the end of the
model number.)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light

NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
Battery protection system (Lithium-ion
battery with star marking) (Fig. 3)
Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically cuts
off power to the appliance to extend battery life.
The appliance will automatically stop during operation if
the appliance and/or battery are placed under one of the
following conditions:
• Overloaded:
The appliance is operated in a manner that causes
it to draw an abnormally high current.
In this situation, switch off the appliance and stop
the application that caused the appliance to
become overloaded. Then restart the appliance.
If the appliance does not start, the battery is
overheated. In this situation, let the battery cool
before restarting the appliance.
• Low battery voltage:
The remaining battery capacity is too low and the
appliance will not operate. In this situation, remove
and recharge the battery.
