6. 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. 18)
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.
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,
significantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, significantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to five 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 modified (such as
disassembly and replacement of cells or other internal
parts).
GUARANTEE
We guarantee Hitachi Power Tools in accordance with
statutory/country specific regulation. This guarantee does
not cover defects or damage due to misuse, abuse, or
normal wear and tear. In case of complaint, please send
the Power Tool, undismantled, with the GUARANTEE
CERTIFICATE found at the end of this Handling instruction,
to a Hitachi Authorized Service Center.
Information concerning airborne noise and vibration
The measured values were determined according to
EN60745 and declared in accordance with ISO 4871.
Measured A-weighted sound power level:
Measured A-weighted sound pressure level:
Uncertainty K: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Hammer drilling into concrete:
Vibration emission value
Uncertainty K = 1.5 m/s
Equivalent chiselling value:
Vibration emission value
Uncertainty K = 1.5 m/s
The declared vibration total value has been measured in
accordance with a standard test method and may be used
for comparing one tool with another.
It may also be used in a preliminary assessment of exposure.
WARNING
○ The vibration emission during actual use of the power
tool can differ from the declared total value depending in
the ways in which the tool is used.
○ Identify safety measures to protect the operator that
are based on an estimation of exposure in the actual
conditions of use (taking account of all parts of the
operating cycle such as the times when the tool is
switched off and when it is running idle in addition to the
trigger time).
NOTE
Due to HITACHI's continuing program of research and
development, the specifications herein are subject to
change without prior notice.
