is off, turn the strength selector dial
to the left until the battery charge indicator comes on.

hot/Cold Pack Delay
When the appliance detects a battery pack that is too hot
or too cold, it automatically starts a Hot/Cold Pack Delay,
suspending charging until the battery pack has reached an
appropriate temperature. The appliance then automatically
switches to the pack charging mode. This feature ensures
maximum battery pack life.
A cold battery pack may charge at a slower rate than a warm
battery pack.
Electronic Protection System
Li‑Ion tools are designed with an Electronic Protection
System that will protect the battery pack against overloading,
overheating or deep discharge. The tool will automatically
turn off and the battery pack will need to be recharged.
Important Charging Notes
1. The power supply and battery pack may become warm
to the touch while charging. This is a normal condition,
and does not indicate a problem. To facilitate the cooling
of the battery pack after use, avoid placing the power
supply or battery pack in a warm environment such as in
a metal shed or an uninsulated trailer.
2. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp
or other appliance;
b. Check to see if receptacle is connected to a light
switch, which turns power off when you turn out
the lights;
c. If charging problems persist, take the appliance,
battery pack, and power supply to your local
service center.
3. You may charge a partially used pack whenever you
desire with no adverse effect on the battery pack.
