Declaration of noise and vibration statement (ISO 15744 and ISO 28927-2)
All values are current as of the date of this publication. For the latest information please visit www.cp.com.
These declared values were obtained by laboratory type testing in accordance with the stated standards and are suitable for comparison with the declared values of other tools
tested in accordance with the same standards. These declared values are not adequate for use in risk assessments and values measured in individual work places may be
higher. 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 upon the exposure time and the physical condition of the user. We, CHICAGO PNEUMATIC TOOLS , 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. This tool may cause
hand-arm vibration syndrome if its use is not adequately managed. An EU guide to managing hand-arm vibration can be found at www. pneurop.eu/uploads/documents/pdf/PN3-
02-NV_Declaration_info_sheet_0111.pdf. We recommend a programme of health surveillance to detect early symptoms which may relate to noise or vibration exposure, so that
management procedures can be modified to help prevent future impairment.
