LOW-BATTERY
CAPACITY
iNDiCATOR
If the LED worklight
begins to rapidly and continuously
flash when the trigger
switch on the Driver is depressed,
the battery pack power has run out, and the
battery pack should
be recharged.
Unlike other battery
pack types, Lithium-Ion
battery packs deliver fade-free
power for their entire run time. The tool will not experience
a slow, gradual loss
of power as you work. To signal that the battery
pack is at the end of its run time
and needs to be charged,
the power to the tool will drop quickly.
NOTE: The LED may also flash due to an overload or high temperature
(see
BATTERY PROTECTION).
BATTERY
PROTECTION
The battery circuitry
protects
the battery pack from extreme temperature,
over-
discharge,
and over-charge.
To protect
the battery from damage and prolong its
life, the battery
pack circuitry
will turn off the battery pack if it becomes
over-
loaded or if the temperature
becomes
too high during use. This may happen in
extremely
high torque, binding,
and stalling situations.
This intelligent
system will
shut down your battery
pack if its operating
temperature
exceeds
176°F (80°C)
and will begin normal operation
when it returns to 32°F (0°C) - 122°F (50°C).
The LED worklight
light will begin flash slowly if the battery circuitry
detects
a
momentary
overload.
NOTE: The battery can automatically
reset. If the LED continues
to flash rapidly,
it is indicating
that the charge
is substantially
diminished.
Place the battery
into
the charger for charging.
(See BATTERY CAPACITY
INDICATOR,
above.)
NOTE: A significantly
reduced run time after fully charging the battery pack indi-
cates that the battery
is near the end of its usable life and must be replaced.
COLD WEATHER
OPERATION
This Lithium-Ion
battery pack will provide optimal performance
in temperatures
between 32°F (0°C) and 104°F (40°C). When the battery pack is very cold, it may
"pulse" for the first minute of use to warm itself. Put the battery pack on a tool
and use the tool in a light application.
After about a minute, the battery pack will
have warmed
itself and will operate normally.
WHEN TO CHARGE
THE BATTERY
PACK
It is not necessary
to run down the battery
pack charge
before recharging.
The
Lithium-Ion
battery can be charged at any time and will not develop a "memory"
when charged after only a partial discharge.
Remove the battery
pack from the tool when convenient
for you and your job.
"Top off" the battery pack charge by charging
it for a time before starting a big
job or long period of use.
