Noise and Vibration Data

K-value (uncertainty) for sound pressure levels is 2 dB(A). K-value (uncertainty) for sound power levels is 2 dB(A). K-value (uncertainty) for vibration levels is 2 m/s².
STIHL recommends that you wear hearing protection.

Sound pressure level LpA measured according to EN 50636-2-100: 79 dB(A)
Sound power level LwA measured according to EN 50636-2-100: 90 dB(A)
Vibration level ahv measured according to EN 50636-2-100, control handle: < 2.5 m/s².

The vibration values quoted above have been measured according to a standardized test pro‐cedure and may be used to compare electric power tools. Depending on the type of usage, the vibrations that actually occur may differ from the values quoted.
