Overloading
If the tool is overloaded for any reason the internal
electronics will cause it to stop working. This safety
feature will prevent under voltage, over temperature, and
over current damage to the tool or battery. Release the
trigger to resume operation.
The following conditions may cause temporary shut-
down of the tool as a safety feature to the user, as well as
to prolong the life of the tool and battery.
— Battery under voltage protection - indicated by
both white LED lights flashing once on the tool,
pausing and then repeating the single flash. This
means the voltage has reached the lowest limit
allowed by the battery manufacturer and the tool
will stop operation to prolong battery life. The
battery voltage may recover after a small rest
period to do more work but the battery will need
charging.
— Battery or tool over temperature - indicated by
both white LED lights flashing twice on the tool,
pausing and then repeating the double flash.
When the tool is used under heavy load
continuously, the maximum allowable
temperature of the switch or battery may be
reached, and the tool will temporarily stop
working. A hot tool will cool in about 1 minute. A
hot battery may require over 15 minutes to cool.
When this condition occurs, usually the battery
will be very close to needing recharging. You may
want to use another battery to finish the job.
Note: The battery charger will show a flashing
yellow LED until the battery cools sufficiently to
begin charge. When the tool is cold (less than
4ºF/-20ºC) it may be necessary to run it a few
seconds, without load, to warm up the battery.
— Tool current limit exceeded - indicated by both
white LED lights flashing three times on the tool,
pausing and then repeating the triple flash. When
the tool is used in an extra-heavy duty application,
the current limit may be reached, causing shut-
down of the tool power. A current limit will occur
if the motor is stalled. Tool operation can be
resumed immediately after releasing the trigger.

Battery Charging
1. If charger is supplied with a separate charger cord,
plug cord into charger.
2. Plug the other end of charger into the AC power source.
3. Insert battery pack in charger. Press lightly on battery
pack until it stops. The charger is equipped with a 4-LED
fuel gauge that indicates 25%, 50%, 75% and 100%
state of charge. When the battery makes contact, all 4
green LEDs on the fuel gauge of the charger will flash
twice and then the charger will step through the 4 LEDs
and stop at the one flashing green LED that signifies the
battery state of charge and that the battery is charging.
4. Certain built-in safety protections may lock the charger
off. If no charger light illuminates, remove the battery
and unplug the charger for 10 minutes. Plug the charger
back in and insert a known good battery. If no light
comes on the charger is faulty and must be replaced.
5. The charger will not charge if the battery pack is too hot
or too cold. The charger will show a flashing yellow LED
and wait until the battery temperature is between 32°F
(0°C) and 113°F (45°C) to begin fast charging.
6. Standard fast charging time is 30 minutes. Charger may
take longer than 30 minutes. The charge cycle may be
longer if the battery has been left in a low state of charge
for an extended period of time. When the charge is
complete, all 4 green LED’s stay illuminated.
7. A flashing red LED indicates the battery is faulty and the
charger will not charge. Remove the battery from the
charger and replace the battery.
