These values make it possible to assess the
emissions from the power tool and to compare
different power tools. The actual load may be higher
or lower depending on operating conditions, the
condition of the power tool or the accessories used.
Please allow for breaks and periods when the load
is lower for assessment purposes. Arrange
protective measures for the user, such as
organisational measures based on the adjusted
estimates.
