CHARGING PROCEDURE
NOTE: Before using the tool, read the
instruction book carefully.
CHARGING INSTRUCTIONS
1. CHARGING YOUR BATTERY PACK
WARNING: The charger and battery pack are
specically 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 partly charged and needs to be
fully charged before rst use.
3. HOW TO CHARGE YOUR BATTERY
CHARGING PROCEDURE
1) Plug the charger into an appropriate outlet (220-
240 V).
2) Slide the battery pack into the charger as shown
in illustration A, the LIGHT will become green and
ash to show charging has started.
3) After charging approx. 40 mins (2.0Ah)/ 50 mins
(2.5Ah)/80 mins (4.0 Ah)/100 mins (5.0Ah), the
light will stay green without ashing, which
means the battery is fully 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.
A
CHARGING INDICATOR
This charger is a “smart charger” that is designed to
provide you information on the status of your battery
charge. Indicator lights n the table below will show
the charging status.
If you receive a defective battery indication light (red
on), insert a new battery 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 (the light will be red and ash), its
internal fan will rapidly cool the battery to the
correct temperature. When the charger detects a
battery pack that is too cold (the light will be red
and ash), 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 ash). 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
ash). 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 ash). 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.
MOUNTING CHARGER ONTO THE WALL
Install screws (not provided ) in the wall .Use screws
sufciently strong to hold the combined weight of
the charger and battery pack. (See Fig. B)

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 (180C-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
sufcient 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 180C-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.
MAINTAIN TOOLS WITH
CARE
Remove the plug from the socket before carrying
out any adjustment, servicing or maintenance.
Your tool requires no additional lubrication or
maintenance. Never use water or chemical cleaners
to clean your power tool. Wipe clean with a dry cloth.
Always store your power tool in a dry place.
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly
qualied persons in order to avoid a hazard.
PROBLEM SOLUTION
1. I CANNOT FIT THE BATTERY INTO THE
BATTERY CHARGER. WHY?
a) Check if the charger and the battery pack are
specically 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 ash 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 nd an appropriate environment with
proper air temperature to start charging.
