5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out

How to make the batteries perform longer.
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.
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:
● Repair is required if the receptacle is not secured
properly or the power cord does not stay in the
receptacle. Consult your electrician. Using the
charger in this condition may lead to fire.
● If the charge status lamp is blinking orange rapidly
(in 0.2 second intervals) and the buzzer sounds
intermittently for 5 seconds, check that the hole
for connecting the battery is not obstructed.
Remove any obstructions. If no obstructions are
found, the battery or charger may be
malfunctioned. Return both to your place of
purchase.
● If the charge time lamp does not light when the
power cord is connected to the receptacle,
disconnect the power cord, and check that the
battery is attached correctly.
● The battery retains heat when used or left for
prolonged periods in direct sunlight. In this state,
