WARNING:
Always wear safety goggles or safety
glasses with side shields when operating tools.

into your eyes, resulting in possible serious injury.
CHARGING BATTERY PACK
The battery pack for this tool has been shipped in a low
charge condition to prevent possible problems. Therefore,
you should charge it until light on front of charger changes
from red to green.
Note: Batteries will not reach full charge the first time they
are charged. Allow several cycles (cutting followed by
recharging) for them to become fully charged.
TO CHARGE
Charge battery pack only with the charger provided.
Make sure power supply is normal house voltage,
120 volts, 60 Hz, AC only.
Connect charger to power supply.
Attach battery pack to charger by aligning raised ribs
on battery pack with grooves in charger, then slide
battery back onto charger. See Figure 8.
CHARGER
Red light should turn on. Red light indicates fast
charging mode.
If red light is flashing, this indicates battery pack is
deeply discharged or hot.
If battery pack is hot, red light should become steady
after battery pack has cooled down.
If battery pack is deeply discharged, red light should
become steady after voltage has increased, normally
within 60 minutes.

IMPORTANT INFORMATION FOR RECHARGING
ATTACH
HOT BATTERIES
Under extreme continuous use, the batteries in your
battery pack will become hot. You should let a hot battery
pack cool down for approximately 1 hour before attempt-
ing to recharge. When the battery pack becomes dis-
GROOVES
charged and is hot, this will cause the red light on your
Fig. 8
battery charger to flash. When battery pack cools down,
red light will glow continuously indicating fast charging
mode, 1 hour charge time. Once the battery pack cools
down, it will recharge battery pack in fast charging mode
as normal.
Note: This situation only occurs when extreme continuous
use of your saw causes the batteries to become hot. It
does not occur under normal circumstances. Refer to
"CHARGING BATTERY PACK" for normal recharging of
batteries. If the charger does not charge your battery pack
under normal circumstances, return both the battery pack
and charger to your nearest Sears repair center for
electrical check.

If after one hour red light is still flashing, this indicates
a defective battery pack and should be replaced.
Green light on indicates battery pack is fully charged
and slow charging to maintain battery pack.
Yellow light on and red light flashing indicates defective
battery pack. Return battery pack to your nearest
Sears Repair Center for checking or replacing.
When your battery pack becomes fully charged, the
red light will turn OFF and the green light will turn ON.
After normal usage, 1 hour of charging time is required
to be fully charged. A minimum charge time of 1-1/2
hours is required to recharge a completely discharged
battery pack.
The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
Do not place charger in an area of extreme heat or
cold. It will work best at normal room temperature.
When the batteries become fully charged, unplug your
charger from power supply and remove the battery
pack.
