• An extension cord must have adequate wire size (,4 WG or American Wire Gauge)
for safety. The smaller the gauge number of the wire, the greater the capacity of the
cable, that is 16 gauge has more capacity than 18 gauge. An undersized cord will cause
a drop in line voltage resulting in loss of power and overheating. When using more than
one extension to make up the total length, be sure each individual extension contains at
least the minimum wire size. The following table shows the correct size to use depending
on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

Using Automatic Tune.Up
TM
Mode
The automahc Tune-Up
TM
Mode equahzes or balances the mdwldual cells in the battery pack
allowing it to funchon at peak capacity. Battery packs should be tuned up weekly or after
10 charge/discharge cycles or whenever the pack no longer dehvers the same amount of
work. To use the automahc Tune-Up
TM,
place the battery pack in the charger and leave it for
at least 8 hours. The charger will cycle through the following modes.
1. The red hghtwill bhnk conhnuously mdlcahng that the 1-hour charge cycle has started.
2. When the 1-hour charge cycle is complete, the hghtwill stay on conhnuously and will no
longer bhnk. This indicates that the pack is fully charged and can be used at this hme.
3. If the pack is left in the charger after the mlhal 1-hour charge, the charger will begin the
Automahc Tune-Up
TM
mode. This mode conhnues up to 8 hours or unhl the indwldual cells
in the battery pack are equahzed. The battery pack is ready for use and can be removed
at any hme dunng the Automahc Tune-Up
TM
mode.
4. Once the Automahc Tune-Up
TM
mode Is complete, the charger will begin a maintenance
charge; the red indicator will remain hr.

Charge Indicators
Some chargers are designed to detect certain problems that can anse with battery packs.
Problems are indicated by the red hght flashing at a fast rate. If this occurs, re-insert battery
pack into the charger. If the problem persists, try a d#ferent battery pack to determine if the
charger is OK. If the new pack charges correctly, then the ongmal pack is defectwe and should
be returned to a service center or other collechon site for recychng. If the new battery pack
ehclts the same trouble indlcahon as the ongmal, have the charger tested at an authonzed
service center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that
is hot, it automahcally starts a Hot Pack Delay, suspending charging until the battery has
cooled. After the battery has cooled, the charger automatically switches to the Pack Charging
mode. This feature ensures maximum battery hfe.The red hghtflashes long, then short while
in the Hot Pack Delay mode.
PROBLEM POWER LINE
Some chargers have a Problem Power One indicator. When the charger is used with some
portable power sources such as generators or sources that convert DC to AC, the charger
may temporanly suspend operahon, flashing the red light with two fast blinks followed by
a pause. This indicates the power source is out of hmlts.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red hghtglowing indefinitely. The
charger will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery
pack has not been kept on maintenance charge, it may need to be recharged before use.
A battery pack may also slowly lose its charge if left in a charger that is not plugged into an
appropnate AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such battenes are
still usable but should not be expected to perform as much work. The charger will indicate to
replace battery pack.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged when the
air temperature is between 65-F and 75-F (18-- 2€C). DO NOT charge the battery pack
in an air temperature below +40-F (+4.5-C), or above +105-F (+40.5-C). This is important
and will prevent senous damage to the battery pack.
2. The charger and battery pack may become warm to touch while charging. This is a normal
condmon, and does not indicate a problem. To facilitate the coohng of the battery pack
after use, avoid placing the charger or battery pack in a warm enwronment such as in a
metal shed, or an unmsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other apphance;
b. Check to see if receptacle is connected to a hghtswitch which turns power off when you
turn out the hghts;
c. Move charger and battery pack to a Iocahon where the surrounding air temperature is
approximately 65-F - 75-F (18-- 2€C);

d. If charging problems persist, take the tool, battery pack and charger to your local
service center.
4. The battery pack should be recharged when it fails to produce sufficient power on jobs
which were easily done prewously. DO NOT CONTINUE to use under these condmons.
Follow the charging procedure. You may also charge a partially used pack whenever you
desire with no adverse affect on the battery pack.
5. Under certain condmons, with the charger plugged into the power supply, the exposed
charging contacts reside the charger can be shorted by foreign material. Foreign matenals
of a conductive nature such as, but not hmlted to, gnndmg dust, metal chips, steel wool,
aluminum foil, or any buildup of metalhc particles should be kept away from charger
cawhes. Always unplug the charger from the power supply when there is no battery pack
in the cawty. Unplug charger before attemphng to clean.
6. Do not freeze or immerse charger in water or any other hquld.
,& WARNING: Shock hazard. Don't allow any liquid to get inside charger. Electric shock may
result.
,& CAUTION: Never attempt to open the battery pack for any reason. If the plastic housing of
the battery pack breaks or cracks, return to a service center for recycling.
Storage Recommendations
1. The best storage place is one that is cool and dry away from direct sunhght and excess
heat or cold.
2. Long storage will not harm the battery pack or charger. Under proper condmons, they can
be stored for 5 years or more.
