NOTE: Before using the tool, read the
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 25min (WA3525)/17min

(WA3520), 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 next
table). 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.
NOTE: A battery pack will slowly lose its charge
when kept out of the charger or left in an
unplugged charger for a long time. It may need
to be recharged before use.

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
