CHARGER DIAGNOSTICS
This charger is designed to detect certain
problems that can arise with the battery packs
or the power source. Problems are indicated
by one LED flashing in different patterns.
BAD BATTERY
_The charger can detect a weak
or damaged battery. The red LED
flashes in the pattern indicated on the
label. If you see this bad battery blink
pattern, do not continue to charge the
battery. Return it to a service center or a
collection site for recycling.
HOT/COLD PACK DELAY
_When the charger detects a battery
that is excessively hot or excessively
cold, it automatically starts a Hot/Cold
Pack Delay, suspending charging until the
battery has normalized. After this happens,
the charger automatically switches to the
Pack Charging mode. This feature ensures
maximum battery life. The red LED flashes
in the pattern indicated on the label when
the hot / cold pack delay is detected.
IMPORTANT CHARGING NOTES
1. Longest life and best performance can
be obtained if the battery pack is charged
when the air temperature is between 60°F
and 80°F (16 °- 27°C). DO NOT charge
the battery pack in an air temperature
below +40°F (+4.5°C), or above +105°F
(+40.5°C). This is important and will
prevent serious damage to the battery
pack.
2. The charger and battery pack may
become warm to touch while charging.
This is a normal condition, and does
not indicate a problem. To facilitate the
cooling of the battery pack after use,
avoid placing the charger or battery pack
in a warm environment such as in a metal
shed, or an uninsutated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by
plugging in a lamp or other appliance
b. Check to see if receptacle is
connected to a light switch which
turns power off when you turn out
the lights.
c. Move charger and battery pack
to a location where the surrounding
air temperature is approximately 6O°F
_80OF (16° - 27°C).
d. If charging problems persist, take
the tool, battery pack and charger
to a qualified service center for
inspection and possible repair.
4. The battery pack should be recharged
when it fails to produce sufficient power on
jobs which were easily done previously.
DO NOT CONTINUE to use under these
conditions. Follow the charging procedure.
You may also charge a partially used pack
whenever you desire with no adverse
affect on the battery pack.
5. Foreign materials of a conductive
nature such as, but not limited to, steel
wool, aluminum foil, or any buildup of
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 cavity. Unplug
charger before attempting to clean.
6. Do not freeze or immerse charger in
water or any other liquid.
zLWARNING:
SHOCK HAZARD. Do not
allow any liquid to get inside charger. NEVER
ATTEMPT TO OPEN THE BATTERY PACK
FOR ANY REASON. IF THE PLASTIC
HOUSING OF THE BATTERY PACK
BREAKS OR CRACKS, RETURN TO A
SERVICE CENTER FOR RECYCLING.
STATE OF CHARGE iNDiCATOR
The battery is equipped with a state
of charge indicator. This can be used
to display the current level of charge
in the battery while in the mower and
during charging. It does not indicate
tool functionality and is subject to
variation based on product components,
temperature and end-user application.
Checking state of charge during use:
• Press the state of charge indicator
button (A1).
• The four LEDs (A2) will illuminate
indicating the percent of charge in the
battery. See chart in figure A.
• If LED light does not illuminate, charge
battery.
