instruction book carefully.

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) Plug the charger into an appropriate outlet.

2) Slide the battery pack into the charger. The

LIGHT (3) will become green and flash to show
charging has started.

3) After charging approx 45min/1 hour, the light

will stay green without flashing, 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

Battery Charger EN

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 65

0

F and 750 F

(18

0

-240C). Do not charge the battery pack in air

temperatures below 40

0

F (4.50C), or above 105

0

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
approximately 65

0

F and 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.

7. An extension cord should not be used unless
absolutely necessary. Use of improper
extension cord could result in a risk of fire and
electric shock. If an extension cord must be
used, make sure:

a. That pins on plug of extension cord are the

same number, size and shape as those of
transformer on charger,

b. That extension cord is properly wired and in

good electrical condition, and

c. That you use a proper extension cord.
ONLY use cords listed by Underwriters

Laboratories (UL) and/or Canadian Standard
Association (CSA). Other extension cords can
cause a drop in line voltage, resulting in a loss
of power and overheating of charger. An AWG
(American Wire Gauge) size of at least 14-gauge
is recommended for an extension cord of 25-ft,
or less in length. Use 12-gauge for an extension
cord of 50-ft. Extension cords 100-ft. or longer
are not recommended.
