Hilti NURON NBL 4-22 Manual De Instrucciones página 23

An accurate estimation of exposure should also take into account the times when the tool is switched off, or
when it is running but not actually being used for a job. This can significantly reduce exposure over the total
working period.
Identify additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: maintaining the power tool and accessory tools, keeping the hands warm, organization of work
patterns.
