Noise & Vibration Declaration*
Sound pressure level 94 dB(A) impacting, 100 dB(A) free
speed, uncertainty 3 dB(A), in accordance with ISO
15744-2002. For sound power, add 11 dB(A).

For making estimates of daily vibration exposures, useful
information may be found in CEN/TR 15350: 2006,
"Mechanical vibration - Guideline for the assessment of
exposure to hand-transmitted vibration using available
information including that provided by manufacturers of
machinery"
* These declared values were obtained by laboratory
type testing in compliance with the stated standards and
are not adequate for use in risk assessments. Values
measured in individual work places may be higher than
the declared values. The actual exposure values and risk
of harm experienced by an individual user are unique
and depend upon the way the user works, the workpiece
and the workstation design, as well as upon the
exposure time and the physical condition of the user.
We, Chicago Pneumatic, cannot be held liable for the
consequences of using the declared values, instead of
values reflecting the actual exposure, in an individual risk
assessment in a work place situation over which we have
no control.
