OPERATION
WARNING:
Always wear safety goggles or safety glasses with side
shields when operating tools. Failure to do so could result
in objects being thrown into your eyes, resulting in possible
serious injury.
WARNING:
Do not allow familiarity with your circular saw to make you
careless. Remember that a careless fraction of a second
is sufficient to inflict severe injury.
CHARGING BATTERY PACK WITH CHARGER
PART NUMBER 1400667
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
■ Connect charger to power supply.
■ 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.
■ Place battery pack in charger aligning raised rib in
charger with groove in battery pack.
■ Press down on battery pack to be sure contacts on
battery pack engage properly with charger contacts.
■ Normally, the yellow and green lights on charger will
come on. This indicates charger is in soft start mode and
should switch to fast charge mode within 5 minutes.
When charger is in fast charge mode the red light will
come on. If after a period of 15 minutes the yellow and
green lights remain on, remove battery pack, wait 1
minute and reinsert battery pack in charger. If the yellow
and green lights continue to remain on after an additional
15 minutes, the battery pack is damaged and will not
accept a charge. Return battery pack to your nearest
Ryobi Authorized Service Center for checking or replac-
ing.
■ 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 tool.
■ 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.
LED FUNCTION OF CHARGER
LED WILL BE LIGHTED TO INDICATE STATUS OF
CHARGER AND BATTERY PACK:
■ Red LED Lighted = Fast Charging Mode.
■ Green LED Lighted = Fuly Charged Or In Slow Charging
Mode To Maintain Battery Pack.
■ Yellow and Green LED Lighted = Soft Start Mode, or After
1/2 Hour Equals Hot or Defective Battery Pack.
IMPORTANT INFORMATION FOR RECHARG-
ING HOT BATTERIES USING CHARGER
PART NUMBER 1400667
See Figure 2.
When using your circular saw continuously, the batteries in
your battery pack will become hot. You should let a hot
battery pack cool down for approximately 30 minutes be-
fore attempting to recharge. When the battery pack be-
comes discharged and is hot, this will cause the yellow and
green lights on your battery charger to come on instead of
the red light. The yellow and green lights indicate soft start
mode and will switch to green only, indicating slow charge
mode. The red light indicates fast charge mode, 1 hour
charge time. The green light indicates slow charge mode,
requiring overnight charging for batteries to reach full charge.
If the green light comes on after letting battery pack cool
down, remove it from charger for additional cooling.
Once the battery pack cools down, it will recharge battery
pack in fast charging mode as normal.
Do not leave a hot battery pack in charger until it cools
down. The green light will not go off when battery pack
cools. If fast charge mode is desired, you must physically
remove a hot battery pack from the charger, let it cool, then
place it back in charger after it has cooled down.
NOTE: This situation only occurs when continuous use of
your saw causes the batteries to become hot. It does not
occur under normal circumstances. Refer to "CHARG-
ING BATTERY PACK WITH CHARGER PART NUMBER
1400667" for normal recharging of batteries. If the charger
does not charge your battery pack under normal circum-
stances, return both the battery pack and charger to your
nearest Ryobi Authorized Repair Center for electrical check.
