5. Cleaning of the battery installation compartment
After drilling concrete, if concrete dust has
accumulated on the terminals or the area where
the battery slides within the battery installation
compartment, clean off the accumulated
concrete dust with a dry cloth before using the
tool. (Fig. 29)
Also, after cleaning, ensure that the battery can
be installed and removed smoothly from the tool.
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.
6. 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.
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 Hitachi 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).
