liminary assessment of the vibrational impact.
The declared vibration emission level repre-
sents the main applications of the power tool.
However, if the power tool is used for other
applications with different accessories or
poorly maintained, the vibration emission
may differ. This may significantly increase the
vibrational impact over the total working
period.
An estimation of the level of exposure to
vibration should also take into account the

If the use of an extension cord

is required, its length and con-
ductor cross-section must be adequate for the
application in order to prevent a voltage drop
in the extension cord, power loss and over-
heating of the power tool. Otherwise, the
extension cable and power tool are prone to
electrical danger, and the working efficiency is
decreased.
times when the tool is switched off or when
it is running but not actually doing the job.
This may significantly reduce the vibrational
load over the total working period.
Identify additional safety measures to protect
the operator from the effects of vibration
such as: Maintain the power tool and the
accessories, keep the hands warm, organiza-
tion of work patterns.
