OPERATION
BATTERY PROTECTION
The integrated protective circuitry prevents 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 the temperature becomes too high during use.
NOTE:
The battery can automatically reset after it cools down.
NOTE:
A significantly reduced run time after fully charging the battery
pack indicates that the battery is near the end of its usable life and must be
replaced.
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:
The 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).
1. Charge the Lithium-Ion battery pack
with the correct charger.
2. Connect the charger to a power supply.
3. Align the raised ribs of the battery pack with the slot in the charger.
4. Insert the battery pack into the charger (Fig. 2).
