  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.

CAUTION

• In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.
• Important notice on the batteries for the HiKOKI cordless power tools
• 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 change without prior notice.
