OPERATION
BATTERY PROTECTION
To protect the battery from damage and prolong its life, the battery pack’s
circuitry will 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. The battery pack will begin
normal operation when it cools down.
NOTE: A significantly reduced run time after fully charging the battery pack
indicates that the batteries are near the end of their usable life and must be
replaced.
COLD WEATHER OPERATION
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.
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.
HOW TO CHARGE THE BATTERY
PACk
NOTE:
This Lithium-Ion battery pack
is shipped partially charged. Before
using it the first time, fully charge the
battery pack.
A fully discharged battery pack
will charge in about 30 minutes in a
surrounding temperature between
50°F (10°C) and 104°F (40°C).
