4. Replacing supply cord
If the replacement of the supply cord is necessary, it has
to be done by Hitachi Authorized Service Center to avoid
a safety hazard.
5. Maintenance of the motor
WARNING
Always wear protective goggles and dust respirators
when blowing air from the tail cover air hole with the use
of an air gun, etc.
Failure to observe this may result in ejected dust being
inhaled or entering your eyes.
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.
NOTE
When work has been fi nished, blow air containing no
moisture from the tail cover air hole with the use of an
air gun, etc., while running the motor without any load
applied. This is eff ective in removing any dirt and dust
that has accumulated. Dirt and dust collecting inside the
motor may result in malfunctions.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.

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
EN60745 and declared in accordance with ISO 4871.
Measured A-weighted sound power level: 102 dB (A).
Measured A-weighted sound pressure level: 91 dB (A).
Uncertainty K: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Surface grinding:
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 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
