MAINTENANCE AND INSPECTION

CAUTION
Pull out battery before doing any inspection or
maintenance.
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
reduced cutting effi ciency and may cause overloading of
the motor. Replace the blade with a new one as soon as
excessive abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Cleaning on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
5. 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).
GUARANTEE
We guarantee Hitachi power tools in accordance with
statutory/country specifi c 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: 98 dB (A).
Measured A-weighted sound pressure level: 87 dB (A).
Uncertainty K: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Cutting boards:
Vibration emission value
Uncertainty K = 1.5 m/s
2
Cutting sheet metal:
Vibration emission value
Uncertainty K = 2.8 m/s
2
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 diff er 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 specifi cations herein are subject to
change without prior notice.
