BATTERY REMOVAL/INSTALLATION
1. Battery removal
Hold the handle tightly and push the battery latch
to remove the battery (see Figs. 1 and 2).
CAUTION
Never short-circuit the battery.

CHARGING
Before using the impact drill, charge the battery as
follows.
1. Insert the battery in the charger.
Position the battery so that the nameplate faces
toward the nameplate of the charger and press in
the battery until it comes into contact with the
bottom surface. (See Figs. 1 and 3.)
2. Connect the charger power cord to the receptacle.
Connecting the power cord will turn on the charger
(the pilot lamp lights up).
CAUTION
If the pilot lamp does not light up, pull out the
power cord from the receptacle and check the
battery mounting condition.
About 1 hour is required to fully charge the battery
at a temperature of about 20°C. The pilot lamp goes
off to indicate that the batterry is fully charged.
The battery charging time becomes longer when a
temperature is low or the voltage of the power
source is too low.
When the pilot lamp does not go off even if more
than two hours have elapsed after starting of the
charging, stop the charging and contact your
HITACHI AUTHORIZED SERVICE CENTER.
