1. Inspecting the saw blade
Since use of a dull saw blade will degrade efficiency
and cause possible motor malfunction, sharpen or
replace the saw blade as soon as 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, re-tighten them immediately. Failure to do
so could result in serious hazard.
3. Inspecting the carbon brushes (Fig. 10)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush could result in motor trouble, replace a carbon
brush with a new one when it becomes worn to or
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
4. Replacing a carbon brushes
Disassemble the brush cap with a minus-head
screwdriver. The carbon brushes can then be easily
removed.
5. 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.
6. Lubrication
Lubricate the following sliding surfaces once a month
to keep the power tool in good operating condition
for a long time.
Use of machine oil is recommended.
Oil supply points:
* Rotary portion of hinge
* Rotary portion of vise assembly
7. Cleaning
Periodically remove chips and other waste material
from the surface of the power tool with a damp, soapy
cloth. To avoid a malfunction of the motor, protect it
from contact with oil or water.

CAUTION:
Repair, modification and inspection of Hitachi Power
Tools must be carried out by an Hitachi Authorized
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:

Information concerning airborne noise and vibration
The measured values were detewmined according to
EN50144.
The typical A-weighted sound pressure level: 99 dB(A).
The typical A-weighted sound power level: 112 dB (A)
Wear ear protection.
The typical weighted root mean square acceleration
value: 8.4 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.
