Sound Values and Vibration Values

K-value (uncertainty) for sound pressure levels is 2 dB(A). K-value for sound power levels is 2 dB(A). K-value for vibration level is 2 m/s².
STIHL recommends wearing ear defenders.

  • Sound pressure level LpA measured as specified in EN 50636‑2‑91: 81 dB(A)
  • Sound power level LwA measured as specified in EN 50636-2-91: 94 dB(A)
  • Vibration level ahv measured as specified in EN 50636-2-91
  • Control handle: 2.0 m/s².
  • Loop handle: 3.7 m/s².

The vibration levels indicated were measured according to a standardized test method and can be used as a basis for comparing electric power tools.
The vibration levels actually occurring may vary from the values indicated, depending on the type of application. The vibration levels indicated can be used for an initial estimate of the vibration stress. The actual vibration stress has to be estimated. The times when the power tool is switched off and the times when it is switched on but running under no-load can be taken into account in the estimate.
For information on compliance with Employers’
Vibration Directive 2002/44/EC see www.stihl.com/vib.
