Hitachi Koki C 10FCH Handling Instructions Manual page 19

4. About Handling the Motor (see Fig. 1)
Winding of the motor is said to be the heart of this
tool. Exercise utmost caution not to damage the
winding by exposing it to wash oil or water.
NOTE
Accumulation of dust and the like inside the motor
can result in a malfunction.
After using the motor for 50 hours or so, carry out no-
load running, and blow in the dry air from a wind hole
at the motor's rear. Such action is effective to
discharge dust and the like.
5. Inspecting the screws
Regularly inspect each component of the power tool
for looseness.
Re-tighten screws on any loose part.
WARNING
To prevent personal injury, never operate the power
tool if any components are loose.
6. Inspecting the lower guard for proper operation
Before each use of the tool, test the lower guard (see
Fig. 7) to assure that it is in good condition and that it
moves smoothly.
Never use the tool unless the lower guard operates
properly and it is in good mechanical condition.
7. Storage
After operation of the tool has been completed, check
that the following has been performed:
(1) Trigger switch is in OFF position,
(2) Power plug has been removed from the receptacle,
(3) Lock-off button has been removed and stored in a
secure place.
When the tool is not in use, keep it stored in a dry
place out of the reach of children.
8. Lubrication
Lubricate the following sliding surfaces once a month
to keep the power tool in good operating condition
for a long time (Fig. 1 and Fig. 2).
Use of machine oil is recommended.
Oil supply points:
* Rotary portion of hinge
* Rotary portion of vise assembly
9. Cleaning
Periodically remove chips, dust and other waste
material from the surface of the power tool, especially
from the inside of the lower guard with a damp, soapy
cloth. To avoid a malfunction of the motor, protect it
from contact with oil or water.
(Only Model C10FCH)
If the laser line becomes invisible due to chips and the
like adhered onto the window of the laser marker's light-
emitting section, wipe and clean the window with a dry
cloth or a soft cloth moistened with soapy water, etc.

CAUTION
Repair, modification and inspection of Hitachi Power
Tools must be carried out by a Hitachi Authorized
Service Center.
Especially laser device should be maintained by the
authorised agent by laser manufacturer.
Always assign the repair of laser device to Hitachi
Authorised Service Center.
This Parts List will be helpful if presented with the
tool to the Hitachi Authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
MODIFICATIONS
Hitachi Power Tools are constantly being improved
and modified to incorporate the latest technological
advancements.
Accordingly, some parts (i.e. code numbers and/or
design) may be changed without prior notice.
NOTE
Due to HITACHI's continuing program of research and
development the specifications herein are subject to
change without prior notice.
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 code
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
EN61029.
The typical A-weighted sound pressure level: 95 dB (A)
The typical A-weighted sound power level: 108 dB (A)
Wear ear protection.
The typical weighted root mean square acceleration
2
value: 2.6 m/s .
Information for power supply system to be used with
electric tools provided with rated voltage 230 V~
Switching operations of electric apparatus cause voltage
fluctuations.
The operation of this electric tool under unfavorable mains
conditions can have adverse effects to the operation of other
electric apparatus.
With a mains impedance equal or less than 0.29 Ohms
there will probably be no negative effects.
Usually, the maximum permissible mains impedance will
not be exceeded when the branch to the power outlet is
fed from a junction box with a service capacity of 25
ampere or higher.
In case of power failure, or when the power plug is pulled
out, immediately return the switch to OFF position. This
prevents an uncontrolled restart.
