OPERATION
WARNING:
Always wear safety goggles or safety glasses with side
shields when operating this tool. Failure to do so could
result in dust, shavings, or loose particles being thrown
into your eyes, resulting in possible serious injury.
WARNING:
Batteries vent hydrogen gas and can explode in the
presence of a source of ignition, such as a pilot light.
To reduce the risk of serious personal injury, never use
any cordless product in the presence of open flame.
An exploded battery can propel debris and chemicals.
If exposed, flush with water immediately.
CHARGING BATTERIES
See Figures 9 and 10.
The battery pack for this tool has been shipped in a low
charge condition to prevent possible problems. Therefore,
you should charge it prior to use.
Note:
Batteries will not reach full charge the first time they
are charged. Allow several cycles (cutting followed by
recharging) for them to fully charge.
Follow these directions when charging batteries.
■
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. Align raised rib on
battery pack with groove in charger.
■
Press down on battery pack to be sure contacts on
battery pack engage properly with contacts in charger.
When properly connected, red light will turn on. When
your battery pack becomes fully charged, the red light
will turn off and the green light will turn on.
Note:
Normally, the yellow and green lights on the charger
will come on. This indicates charger is in control charge
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 the battery pack, wait 1
minute and reinsert battery pack in charger. If the yellow
and green lights continue to remain on an additional 15
minutes, the battery pack is damaged and will not accept
charge.
See Table 1.
After normal usage, 1 hour of charge time is required to be
fully charged. A minimum charge time of 1 to 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.
RECHARGING HOT BATTERIES
When using your hammer drill continuously, the batteries
in your battery pack become hot. You should let a hot
battery pack cool down for approximately 30 minutes
before attempting to recharge.
Note:
This situation occurs when continuous use of your
hammer drill causes the batteries to become hot. It does
not occur under normal circumstances. Refer to
CHARGING BATTERIES for normal recharging of
batteries. If the charger does not charge your battery pack
under normal circumstances, return
both
the battery pack
and charger/charging assembly to your nearest
Ryobi
Authorized Service Center
for electrical check.
