How to charge the battery pack
(fig 1)
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 3–5 hours in a surrounding temperature
between 0°C (32°F) and 40°C (104°F).
1. Charge the Lithium-Ion battery pack with the
correct charger (5331).
2. Align the raised electric contacts on the charging base with the corresponding slots in the battery
pack, and slide the charging base onto the battery pack (fig 1).
3. Connect the charger to a power supply.
4. The charger will communicate with the battery pack’s circuitry to evaluate the condition of the
battery pack.
5. The Fuel Gauge LED lights will cycle from right to left during charging. This is part of the normal
charging operation.
6. After charging is complete, the green LED on the charger will be on and the Fuel Gauge LED lights
will turn off. The Fuel Gauge LED lights will not be displayed when the Fuel Gauge button is pressed
while the battery pack is on the charger.
7. The battery pack will fully charge, but will not overcharge, if left on the charger.

OPERATING INSTRUCTIONS
Battery protection
To protect the battery from damage and prolong its life, the battery pack 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. The Fuel Gauge will display four flashing LED lights if the circuitry
detects a momentary overload. You can conveniently reset the battery pack by releasing the power tool
trigger switch. Press the Fuel Gauge button again to display the remaining charge.
NOTE:A significantly reduced run time after fully charging the battery pack indicates that the battery
pack is near the end of its usable life and must be replaced.
NOTE: If the Fuel Gauge continues to flash four LED lights after reset, place the battery pack on the
charger to evaluate the battery pack condition.
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 the 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 Fuel Gauge 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.
