CHARGING INSTRUCTIONS
1. CHARGING YOUR BATTERY PACK

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 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 the battery pack into the charger, the LIGHT
will become green and ash to show charging has
started.
3) After charging approx. 45 minutes, the light will stay
green without ashing, which means the battery is
full, and charging is completed.
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 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.
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.
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 18 °C and 24 °C . Do not charge the battery
pack in air temperatures below 0 °C , or above 40 °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 sufcient
power on jobs that were previously done easily, please
recharge you 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
18 °C -24 °C .
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
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.
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.
c) If the battery pack is very hot, remove battery pack
from the charger and allow battery pack to cool rst
to ambient temperature and then recharging can be
started.
MAINTENANCE
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 tool. Wipe clean with a dry cloth. Always store
your 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.
