CHARGING INSTRUCTIONS
1. CHARGING YOUR BATTERY PACK
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) Unwrap cord and plug in the car power supply
interface. (See Fig. 1)
2) Insert the battery pack into the charger, making
sure the battery pack is fully seated into the
charger. (See Fig. 2)
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.
NOTICE: To extend the vehicles battery life,
it is recommended to only use the WA3764
charger while the vehicle is in operation.
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 30 mins (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 650F and 750F
(180-240C). Do not charge the battery pack in air
temperatures below 400F(4.50C), or above 1050
F(40.50 C).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
approximately650and 750F(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.
MAINTAIN TOOLS WITH
CARE
Remove the plug from the socket before
carrying out any adjustment, servicing or
maintenance.
Your battery charger requires no additional
lubrication or maintenance. Never use water or
chemical cleaners to clean your charger. Wipe clean
