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. 25mins (2.0Ah)/ 30mins
(2.5Ah)/50mins (4.0 Ah)/60mins (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.
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)

Battery Charger KA3714
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.
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.
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.
ENVIRONMENTAL
PROTECTION
Waste electrical products must not be disposed
of with household waste. Please recycle where
facilities exist. Check with your local authorities
