Emission values
Using these values, you can estimate the emis-
sions from this power tool and compare these with
the values emitted by other power tools. The actual
values may be higher or lower, depending on the
particular application and the condition of the tool or
power tool. In estimating the values, you should also
include work breaks and periods of low use. Based
on the estimated emission values, specify protective
measures for the user - for example, any organisa-
tional steps that must be put in place.
