Noise/Vibration Information
The measured values of the machine are listed in the table on
page 127.
Noise and vibrational values (vector sum of three directions)
determined according to EN 60745.
The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
1 609 929 X64 | (8.7.11)
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.

Maintenance and Cleaning

For safe and proper working, always keep the machine
and ventilation slots clean.
Service Indicator
(see Fig. 9, page 131)
When the carbon brushes are worn out, the machine switches
itself off. This is indicated approx. 8 hours beforehand by the
lighting or blinking of the service indicator. The machine must
then be sent to an after-sales service agent. Addresses are
listed in the Section "After-sales Service and Customer Assist-
ance".
Service indicator flashes in regular intervals, the machine is
defective. In this case, do not continue to use the machine
and send it immediately to an after-sales service agent.
