# Vibration Front Handle

The vibration transmitted to the operator's hand at the front handle, expressed as an acceleration in m/s². It is one of the two figures used to estimate daily hand-arm vibration exposure.

Hand-arm vibration causes cumulative, permanent nerve and circulatory damage, and it is regulated for exactly that reason: the EU Physical Agents (Vibration) Directive sets a daily exposure action value of 2.5 m/s² A(8) and a limit value of 5 m/s² A(8). Those thresholds are eight-hour averages, so a saw with a higher declared figure is not forbidden — it simply buys you fewer trigger-hours per day. Declared values assume a sharp chain and sound anti-vibration mounts; a blunt chain forces you to push, which increases vibration well beyond the published figure. Compare this row with **Vibration Rear Handle**, since the two hands are rarely exposed equally.
