Maintenance And Inspection - Hitachi WR 22SE Mode D'emploi

English
3. The protection function
To protect the tool, the protection function will be
activated, automatically shutting down the unit in the
event of any problems. (Table 1)
Table 1
Cause of Shutdown
Automatic shutdown initiated by excessive load (*1)
Automatic shutdown initiated due to the tool's internal
temperature exceeding the specifi ed temperature level (*2)
*1 Excessive load protection function
For excessive load conditions, the tool will shutdown to
prevent damage.
Discontinue the heavy load task, unplug the power
supply cord from the electrical outlet and plug it back in
to reset.
*2 Increased temperature protection function
Automatic shutdown is activated to prevent damage
from high temperatures.
The tool's internal temperature will increase for tasks
involving the use of large currents of electricity, or when
used in high temperature environments.
Please allow the tool to rest for 10 to 15 minutes before
continuing a task.

MAINTENANCE AND INSPECTION

1. Inspecting the socket
A worn or deformed hex or a square-holed socket will
not give an adequate tightness to the fi tting between the
nut or anvil, consequently resulting in loss of tightening
torque. Pay attention to wear of socket holes periodically,
and replace with a new one if needed.
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, this
has to be done by the manufacturer of this agent in order
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

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:
Measured A-weighted sound pressure level:
Uncertainty K: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Impact tightening of fasteners of the maximum capacitiy of
the tool:
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
