of 90 dBA (model 02602), 88.5 dBA (model 02604), or 88
dBA (model 02606) which includes an Uncertainty Value (K)
of 2 dBA. The sound pressure level was determined according
to the procedures outlined in EN 836.

Sound Power

This machine has a guaranteed sound power level of 100
dBA (model except 02602) or 98 dBA (models 02604 and
02606), which includes an Uncertainty Value (K) of 2 dBA.
The sound power level was determined according to the
procedures outlined in ISO 11094.

Vibration

Measured vibration level for the left hand = 5.4 m/s2 (models
02602 and 02604) or 4.0 m/s2 (model 02606)
Measured vibration level for the right hand = 6.2 m/s2 (model
02602), 4.3 m/s2 (model 02604), 4.7 m/s2 (model 02606).
Uncertainty Value (K) = 3 m/s2 (model 02602), 2.5 m/s2
(model 02604), or 2 m/s2 (model 02606).
The measured values were determined according to the
procedures outlined in EN 836.
