CAUTION: ALWAYS rest the cordless tool at least 30 minutes before resetting the
output function.
3 Excessive current protection
When continuous excessive current is detected, to prevent cordless tool or charger
breakdowns caused by sudden overheating, stop the output, and the red lamp will
flicker repeatedly.
Rest the cordless tool and 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.)

Even with continuous work spanning long hours, output will not stop during intermittent
work which would use up three Hitachi 2Ah batteries in a half day, because the cordless
tool temperature increase remains low. You can continue to use the tool.
NOTE: If the lamp continues to flicker despite proper use, the charger may be malfunctioning.
Please take the charger to the store where you purchased it.
