Cold Weather Operation - Craftsman NEXTEC 320.33179 Owner's Manual

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 wilt turn off the battery pack if it becomes overloaded or if the
temperature becomes too high during use. This may happen in extremely high torque,
binding, and stalling situations. This intelligent system wilt shut down your battery
pack if its operating temperature exceeds 176°F (80°C) and wilt begin normal
operation when it returns to approximately 122°F (50°C). The battery pack will begin
normal operation when it cools down.
• The LED worklight light will begin flashing slowly if the battery circuitry detects a
momentary overload.
The battery can automatically reset. If the LED continues to flash rapidly, it is indicat-
ing that the charge is substantially diminished. Place the battery into the charger for
charging. (See BATTERY CAPACITY INDICATOR, above.)
COLD WEATHER OPERATION
This Lithium-Ion battery pack wilt 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 it. The
Lithium-Ion battery can be charged at any time and wilt not develop a "memory"
that reduces the battery-charge capacity when the battery is charged after a partial
discharge.
Remove the battery pack from the tool when it is convenient. "Top off' the battery
pack charge by charging it for a time before starting a big job or long period of use.
Due to Lithium-Ion fade-free properties, the only time it is necessary to charge the
Lithium-Ion battery pack is when the pack has reached the end of its charge. To signal
the end of charge, power to the tool will drop quickly. Charge the battery pack as
needed.
TO ATTACH BATTERY PACK
(Fig. 2)
1. Slide the lock ON/OFF button forward
to make sure that the jig saw is "OFF".
2,
Align the raised ribs on the battery pack
with the grooves in the jig saw, and
then insert the battery pack to attach
the battery pack to the saw.
