CAUTION
Using the tool when the battery is covered with concrete
dust may lead to accidents such as the battery falling
during use.
Furthermore, such use may cause a malfunction or
contact failure between the battery and the terminals.
7. Storage
Store the power tool in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.

Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modifi ed (such as
disassembly and replacement of cells or other internal
parts).
NOTE
Due to HiKOKI's continuing program of research and
development, the specifi cations herein are subject to

Charge the battery.
Push in the battery until a click is heard.
Clean off the accumulated concrete dust
with a dry cloth.
Attach the battery when the switch trigger
is OFF.
Get rid of the problem causing the
overburden.
Let the battery cool down.
For the SDS-max shank type, use a bit with
a diameter that is within the designated
range.
Replace with a new drill.
Please install a multi volt type battery.
