WARNING! – Risk of Hand Arm Vibration Injury.
This tool may cause Hand Arm Vibration Syndrome if its use is not managed adequately.
ThistoolissubjecttothevibrationtestingsectionoftheMachineryDirective2006/42/EC.
This tool is to be operated in accordance with these instructions.
Measured vibration emission value (a): .............1.4m/s²
Uncertainty value (k): ............................0.7m/s²
Pleasenotethattheapplicationofthetooltoasolespecialisttaskmayproduceadifferentaveragevibrationemission.Werecommendthata
specific evaluation of the vibration emission is conducted prior to commencing with a specialist task.
A health and safety assessment by the user (or employer) will need to be carried out to determine the suitable duration of use for each tool.
NB:StatedVibrationEmissionvaluesaretype-testvaluesandareintendedtobetypical.
Whilst in use, the actual value will vary considerably from and depend on many factors.
Such factors include; the operator, the task and the inserted tool or consumable.
NB: ensure that the length of leader hoses is sufficient to allow unrestricted use, as this also helps to reduce vibration.
The state of maintenance of the tool itself is also an important factor, a poorly maintained tool will also increase the risk of Hand Arm Vibration
Syndrome.
Health surveillance.
We recommend a program of health surveillance to detect early symptoms of vibration injury so that management procedures can be modified
accordingly.
