CHARGING PROCEDURE
NOTE: Before using the tool, read the
instruction book carefully.
CHARGING INSTRUCTIONS
1. CHARGING YOUR BATTERY PACK
The charger is designed to charge two battery packs
at the same time as well as charge one by one.
WARNING: The charger and battery pack are
specifically designed to work together so do
not attempt to use any other devices. Never insert
or allow metallic objects into your charger or battery
pack connections because an electrical failure and
hazard will occur.
2. BEFORE USING YOUR CORDLESS TOOL
Your battery pack is UNCHARGED and you must
charge once before use.
3. HOW TO CHARGE YOUR BATTERY
CHARGING PROCEDURE
1) Plug the charger into an appropriate outlet.
2) Slide one battery pack or two battery packs
into the charger. Normally, the relevant charge
indicator light (3) will flash in green color
showing the battery is being charged.
WARNING: When battery charge runs
out after continuous use or exposure
to direct sunlight or heat, allow time for the
battery to cool down before re-charging to
achieve the full charge.
CHARGING INDICATOR
This charger is designed to detect some problems
that can arise with battery packs. Indicator lights
indicate problems (see table below). If this occurs,
insert a new battery pack to determine if the charger
is OK. If the new battery charges correctly, then the
original pack is defective and should be returned
to a service center or recycling service center. If the
new battery pack displays the same problem as the
original Battery Pack, have the charger tested at an
authorized service center.

BATTERY TEMPERATURE PROTECTION
This charger has a battery temperature protection
feature. When the charger detects a battery pack that
is too hot or cold (the light will be red and flash), 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 be green and
flash).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 Light will remain green.The battery pack will
remain charging with a maintenance trickle current.
DEFECTIVE BATTERY PACKS
This charger will detect a defective battery pack.
When a defective battery pack is inserted into the
charger, the charger will try to repair it.This process
will last about 30mins (the light will be green and
flash). If the repair is successful, the charger will
automatically begin to charge the battery pack to the
highest capacity possible (the light will be green and
flash). If the light becomes solid red, the battery pack
is dead.
NOTE: Repaired battery packs are still usable but
should not be expected to perform as much work as
new battery packs.
IMPORTANT CHARGING NOTES:
1. For a new battery or a battery that has been
in storage for sometime, please recharge the
battery before use. If you want to store the
battery for a long time, please fully charge the
battery pack to ensure maximum battery life.
2. Longer life and better performance can be
obtained if the battery pack is charged when
the air temperature is between (180-240C). Do
not charge the battery pack in air temperatures
below 00C, or above 400C.This is important as
it can prevent serious damage to the battery
pack.
3. Never freeze your charger or immerse charger
in water or any other liquid.
4. 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.
5. When charging it is normal that the charger and
battery pack may become warm to touch.
6. 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
ok
c. Check whether the battery has been damaged
d. Move the charger and battery pack to a location
where the surrounding air temperature is
approximately 180-240C.
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.
PROBLEM SOLUTION
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.
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) If the battery pack is very hot, remove battery
pack from the charger and allow battery pack
to cool first to ambient temperature and then
recharging can be started.
