OPERATION
COLD WEATHER OPERATION
When the battery pack is very cold, it may
“pulse” for the rst 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
The Lithium-Ion battery can be charged at
any time and will not develop a “memory”
when charged after only a partial discharge.
It is not necessary to run down the battery
pack charge before recharging. Remove
the battery pack from the tool when it is
convenient for you and your job.
1. Use the power indicator to determine when
you need to recharge the battery pack.
2. You can “top-off” your battery pack’s
charge before starting a big job or long
period of use.
3. Due to Lithium-Ion’s 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.
