OPERATING INSTRUCTIONS
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
NOTICE:
This lithium-ion battery pack is shipped partially charged.
Before using it the first time, fully charge the battery pack.
The lithium-ion battery pack can be charged at any time and will not
develop a “memory” if it is charged after only a partial discharge. It
is not necessary to completely discharge the battery pack before
recharging. Remove the battery pack from the tool and recharge it
when it is convenient or when it is not in use.
Use the POWER BAR to determine when the battery pack needs to
be recharged.
It is recommended that the battery pack be brought up to full charge
before starting a big job or using it for an extended period of time.
This lithium-ion battery pack delivers fade-free power, and therefore,
the only time it is necessary to charge it is when the battery pack
has reached the end of its charge. The power delivered to the tool
will drop quickly when the battery pack is at the end of its run time
and needs to be charged. Charge the battery pack as needed.
