BATTERY TEMPERATURE PROTECTION
This charger has a battery temperature protection
feature. When the charger detects a battery pack that
is too hot (the light will flash red), its internal fan will
rapidly cool the battery to the correct temperature.
When the charger detects a battery pack that is too
EN
cold (the light will flash red), it automatically activates
the protection circuit, and suspends charging until
the battery pack has reached the correct temperature
. The charging process will then automatically begin
(the light will flash green). This feature ensures
maximum battery life.
LEAVING THE BATTERY PACK IN THE
CHARGER
If a fully charged battery pack is left in the charger,
the battery pack will enter a sleep low power mode.
IMPORTANT CHARGING NOTES:
1. For long-term storage, please keep the battery
pack at 40%～60% state of charge. It is
suggested to check the battery power level
regularly. During long term storage, battery
should be charged and discharged every 3
months.
2.
Never freeze your charger or immerse charger in
water or any other liquid.
3.
When the battery pack fails to produce sufficient
power on jobs that were previously done easily,
please recharge your battery, do not continue to
use under this condition.
You may charge a partially used pack whenever
you desire with no adverse affect on the battery
pack.
4. When charging, it is normal that the charger and
battery pack may become warm to touch.
5. If the battery pack does not charge properly:
a. Check current at power outlet by plugging in

another appliance.
b. Plug and unplug to check whether the charger is

c. Check if the battery or the charger are damaged
d. Move the charger and battery pack to a location
where the surrounding air temperature is
0
approximately 18 C-25
e. If the charging problem persists, take the tool,
battery pack and charger to an authorized
service center.
f. Under certain conditions, when the charger is
plugged into the power supply, the exposed
charging contacts inside the charger can be
shorted by foreign material. Foreign materials of
a conductive nature such as metallic particles
should be kept away from charger cavities.
Always unplug the charger from the power
supply when there is no battery pack in the
charger or before attempting to clean.
CAUTION: Do not operate or store the charger
in rain or wet condition to avoid electrodes
corrosion and shortening the life. Charge battery
packs after the electrodes are completely dry in
case they are wet. Replace the electrodes if obvious
verdigris appears.

PROBLEM SOLUTION

1.I CANNOT FIT THE BATTERY INTO THE
BATTERY CHARGER. WHY?
a) Check if the charger and the battery pack are
specifically designed for working together.
b) The battery can be inserted into the charger only
in one direction. Turn the battery around until it
can be inserted into the slot, the indicator light
should be green and flash when the battery is
charging.
2. REASONS FOR DIFFERENT CHARGING
TIMES
The charging time can be affected by many reasons
which are not defects in your product.
a) If the battery pack is only partly discharged it may
be re-charged in less than rated charging time.
b) If the battery pack and ambient temperature are
very cold/ hot, it may take longer to re-charge.
Please find an appropriate environment with
proper air temperature to start charging.
c) Batteries of higher Amp Hour rating require more
charging time.
