WARNING
Follow operating instructions to reduce
the risk of injury from electrical shock.
Charging Procedure
New batteries reach their full capacity after ap-
proximately five charging and discharging cy-
cles. It is not necessary to completely dis-
charge a battery pack before recharging.
1. Set up charger according to Inspection
and Assembly section.
2. With dry hands, insert plug into appropri-
ate power source. Route cords to prevent
tripping or cord damage.
3. When charger is in “ready to charge”
mode, the yellow LED light will blink con-
tinuously.
4. With dry hands, insert the battery pack
onto the charger.
(See Figure 7.)
Do not
force the battery into the charger. The
battery pack will begin charging auto-
matically. The battery pack will become
slightly warm to the touch during charg-
ing. This is normal and does not indi-
cate a problem. The LED light on the
battery charger will indicate charging
condition
(Figure 3)
.
Once the battery is charged, it may remain
on the charger until use. There is no risk of
overcharging the battery.
5. When charging is complete, with dry
hands, remove the battery from the
charger and unplug the charger from
outlet.

4. Select an appropriate location for the
charger before use. Check work area
for:
• Flammable liquids, vapors or dust that
may ignite. If present, do not work in
area until sources have been identified
and corrected. Battery charger is not
explosion proof and can cause sparks.
• Clear, level, stable, dry indoor loca-
tion for charger. Do not use in wet or
damp areas.
• Proper charging temperature range.
• Appropriate power source. Confirm
that outlet matches the charger plug.
Use of extension cords is not recom-
mended.
• Sufficient ventilation area. The charger
needs a clearance of at least 3" (76
mm) on all sides to maintain the proper
operating temperature.
