4. Inspecting the carbon brushes (Fig. 6)

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 Numbers

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 securely and to install the

tail cover.

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.

Information concerning vibration

Vibration total values (triax vector sum) determined

according to EN60745.

Chiselling:

Vibration emission value

ah, Cheq = 14.7 m/s

Uncertainty K = 4.5 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

power tool can differ from the declared total value

depending on the ways in which the tool is used.

⅜ 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).
