4. Motor unit maintenance
The motor winding is an important part of this tool. Avoid
damaging and be careful to avoid contact with cleaning
oiI or water. After 50 hours of use, clean the motor by
blowing into the ventilation holes of the motor housing
with dry air from an air gun or other tool (Fig. 17). Dust or
particle accumulation in the motor can result in damage.
5. Inspecting the carbon brushes (Fig. 16)
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 ensue that they slide freely within the
brush holders.
6. Replacing carbon brushes (Fig. 16)
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.
7. 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.
8. Replacing belt
If the replacement of the belt is necessary, it has to be
done by Hitachi Authorized Service Center to avoid a
safety hazard.

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 each 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
EN62841 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 EN62841.
Planing softwood:
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 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
