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.

Information concerning vibration

Vibration total values (triax vector sum) determined according to EN60745.

Chiselling:

Vibration emission value ah, Cheq = 14.7 m/s2 Uncertainty K = 4.5 m/s2

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).
