MAINTENANCE AND INSPECTION
1. Inspecting the tool bits
Since use of a dull tool will cause motor malfunctioning and
degraded effi ciency, replace the tool bit with new ones or
resharpen them without delay when 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. Replacing supply cord
If the replacement of the supply cord is necessary, it
has to be done by HiKOKI Authorized Service Center to
avoid a safety hazard.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
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.
IMPORTANT
Correct connection of the plug
The wires of the main lead are coloured in accordance
with the following code:
Blue: — Neutral
Brown: — Live
As the colours of the wires in the main lead of this tool may
not correspond with the coloured markings identifying the
terminals in your plug proceed as follows:
The wire coloured blue must be connected to the terminal
marked with the letter N or coloured black. The wire
coloured brown must be connected to the terminal marked
with the letter L or coloured red. Neither core must be
connected to the earth terminal.
NOTE:
This requirement is provided according to BRITISH
STANDARD 2769: 1984.
Therefore, the letter code and colour code may not be
applicable to other markets except The United Kingdom.
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: 108 dB (A)
Measured A-weighted sound pressure level: 100 dB (A)
Uncertainty K: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN62841.
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 and the declared noise
emission value have been measured in accordance with a
standard test method and may be used for comparing one
tool with another.
They may also be used in a preliminary assessment of
exposure.
WARNING
○ The vibration and noise emission during actual use
of the power tool can diff er from the declared total
value depending on the ways in which the tool is used
especially what kind of workpiece is processed; and
○ 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.
