Declaration Of Conformity; Adjusting The Riving Knife - Bosch GKS 160 PROFESSIONAL Operating Instructions Manual

Note: To be accurate, an estimation of the level of
exposure to vibration experienced during a given
period of work should also take into account the times
when the tool is switched off and when it is running
but not actually doing the job. This may significantly
reduce the exposure level over the total working
period.
