○ Perform the cutting operation only after the panel is
fi xed securely.
○ Always hold the tool fi rmly with hand on housing.
When cutting thin panels, level the unit horizontally.
To facilitate smooth cutting of thick panels, if the cut-
off side goes toward the left, raise the rear of the unit
slightly. And if the cut-off side goes toward the right,
lower the rear of the unit slightly.
MAINTENANCE AND INSPECTION
1. Inspecting the blade
Using a worn or chipped blade will put an excessive
burden on the motor and aff ect work performance.
Therefore, always use a well-cutting blade.
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. Blade replacement (see Fig. 7)
The hand shear uses disposable blades. Each blade has
8 cutting edges ⓖ. After a cutting edge cuts 400 meters
of panel, cutting performance will fall. Then use another
cutting edge. After all 8 cutting edges ⓖ are used and
worn, replace the blade.
5. Replacing the carbon brushes
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn.
CAUTION
When replacing the carbon brush with a new one, please
take the power tool to the HiKOKI Authorized Service
Center.
6. Storage
Store the cordless disc grinder 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 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).
GUARANTEE
We guarantee HiKOKI 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 HiKOKI Authorized Service Center.
Information concerning airborne noise and vibration
The measured values were determined according to
EN62841 and declared in accordance with ISO 4871.
Measured A-weighted sound power level: 78 dB (A).
Measured A-weighted sound pressure level: 67 dB (A).
Uncertainty K : 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN62841.
Cutting metal sheet:
Vibration emission value
Uncertainty K = 1.5 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 HiKOKI's continuing program of research and
development, the specifi cations herein are subject to
change without prior notice.
