4. Inspecting the carbon brushes (Fig. 31)
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.
The number of the carbon brush will diff er in accordance
with the voltage being used.
5. Replacing the carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed. (Fig. 32)
CAUTION
Be careful not to deform the brush holder during this
operation.
6. 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.
7. 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.

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 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
EN60745 and declared in accordance with ISO 4871.
Measured A-weighted sound power level: 103 dB (A)
Measured A-weighted sound pressure level: 90 dB (A)
Uncertainty KpA: 2 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
a
h = 4.0 m/s
2
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).
