Before Use; Prior To Operation - Hitachi DH 18DBL Instruction Manual

● Since the built-in micro computer takes about
3 seconds to confi rm that the battery being
charged with charger is taken out, wait for a
minimum of 3 seconds before reinserting it to
continue charging. If the battery is reinserted
within 3 seconds, the battery may not be properly
charged.
● If the pilot lamp does not blink in red (every
second) even though the charger cord is
connected to the power, it indicates that
the protection circuit of the charger may be
activated.
Remove the cord or plug from the power and
then connect it again after 30 seconds or so. If
this does not cause the pilot lamp to blink in red
(every second), please take the charger to the
Hitachi Authorized Service Center.

BEFORE USE
