1 Connecting
With the adapter facing the correct direction, insert the adapter into the cordless tool
unit battery insertion socket until it clicks.
2 Disconnecting
To disconnect, firmly grasp the cordless tool unit, press the latches on both sides of
the adapter, and pull out.
(2) Operation
WARNING:
Like operation with the battery, trigger the switch for operation, and release it to stop.
3. DC Power Source Lamp
(1) Normal Use
When the adapter is connected and "power source ready" red lamp is continuously
lit, the cordless tool can be used by triggering the switch.
(2) Output may stop in the following conditions.
1 High temperature protection
Work involving large continuous current and intense continuous work in high
temperature locations will raise the internal temperature of the charger. To prevent
breakdowns caused by high temperatures, stop the output, and the red lamp will
flicker (0.2 second cycle) repeatedly. Rest the charger for at least 30 minutes.
Then, unplug the charger from the outlet, wait 20 seconds, and plug it in again. (This
resets the output function, and restores output voltage.)
2 Continuous overuse protection
When a cordless tool is used continuously for a long time without breaks (such as
work which would consume three Hitachi 2Ah batteries in one hour), stop the output,
and the red lamp will flicker (0.2 second cycle) repeatedly. Rest the cordless tool for
at least 30 minutes.
Then, unplug the charger from the outlet, wait 20 seconds, and plug it in again. (This
resets the output function, and restores output voltage.)
Insert
Pull out
ALWAYS follow the tool unit instruction manual for handling cordless
tools. Extend the output cable during use. Using the cable tightly coiled
risks overheating.
