2. Handling
CAUTION
The front base, rear base, and cutting depth control
knob are precisely machined to obtain specifi cally high
precision. If these parts are roughly handled or subjected
to heavy mechanical impact, it may cause deteriorated
precision and reduced cutting performance. These parts
must be handled with particular care.
3. 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.
4. Inspecting the carbon brushes (Fig. 28)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon brush
No. shown in the fi gure 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.
5. Replacing carbon brushes
After removing the chip cover, use a slotted screwdriver
to disassemble the brush caps. The carbon brushes can
then be easily removed with the spring.
6. 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.
7. Replacing supply cord
If the replacement of the supply cord is necessary, this
has to be done by Hitachi Authorized Service Center in
order to avoid a safety hazard.
8. Service parts list

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: 100 dB (A)
Measured A-weighted sound pressure level: 89 dB (A)
Uncertainty KpA: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Planing softwood:
a
Vibration emission value
Uncertainty K = 1.5 m/s
2
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 on
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).
