FUEL GAUGE
This tool is equipped with a fuel gauge that
tells you how much charge your battery has.
A fully charged battery is indicated when all
three LED lights are illuminated. As the
battery discharges, the lights will turn off one
by one until only one light is on. When the
last light starts "flashing", the battery is
almost empty. When the battery is dead, the
tool will automatically turn off. This will be a
sudden stop as opposed to a gradual
winding down of the tool. Simply recharge
the battery and reuse.
INSERTING AND RELEASING
BATTERY PACK
Release battery pack from tool by pressing on
both sides of the battery release tabs and pull
away from housing.
To insert battery, align battery and slide
battery pack into tool until it locks into position.
Do not force.
CHARGER INDICATORS, SYMBOLS
AND MEANING
If the indicator lights are "OFF", the charger
is not receiving power from power supply
outlet.
If the green indicator light is
"BLINKING", the battery pack is
being fast-charged. Fast-
charging will automatically stop when the
battery pack is fully charged.
IMPORTANT CHARGING NOTES
1. The charger was designed to fast charge
the battery only when the battery temperature
is between 32˚F (0˚C) and 113˚F (45˚C). If the
battery pack is too hot or too cold, the charger
will not fast charge the battery. (This may
happen if the battery pack is hot from heavy
use). When the battery temperature returns to
between 32˚F (0˚C) and 113˚F (45˚C), the
charger will automatically begin charging.
2. A substantial drop in operating time per
