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. Inspecting the carbon brushes (Fig. 11)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or
near the "wear limit", it could result in motor trouble.
When an auto-stop carbon brush is equipped, the
motor will stop automatically. At that time, replace
both carbon brushes with new ones which have the
same carbon brush Number shown in the figure.
In addition, always keep carbon brushes clean and
ensure that they slide freely within the brush holders.
5. Replacing carbon brushes
Loosen the set screw and remove the tail cover.
Remove the brush caps and carbon brushes. After
replacing the carbon brushes, do not forget to tighten
the brush caps properly and install the tail cover.

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 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 vibration
Vibration total values (triax vector sum) determined
according to EN60745.
Chiselling:
Vibration emission value
2
Uncertainty K = 4.3 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 differ 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).
