VIBRATION EMISSION DATA
Declared vibration emission value in accordance with EN 12096: the average measured vibration emission
value is 2.0 m/s². The uncertainty in the measurement is 2.4 m/s². Safety gloves help to isolate the hands
from the vibration, keep them warm and dry, maintain blood circulation, and make operators less
susceptible to vibration induced injury.
The Barreto Stump Grinder, Model E30SG when operated in accordance with its instructions, and tested in
accordance with EN 1033:1995, results in the following vibration emission declared in accordance with EN
12096:1996.

These values are suitable for comparison with the vibration emission levels of other tools that have been
obtained using the same test method.
Note: these figures represent the average value over 5 tests, with the figures in the x, y, and z axes
combined in a vector sum (a
hv
= a
hwx
2
+ a
hwy

+ a

). It is this sum that is averaged over all tests.
Since the value stated above is an average of several tests, and is based on data from all three exes, we
consider it to be a reasonable approximation of the true value, particularly considering the uncertainty in
the results (K).
This machine is unlikely to cause hand-arm vibration syndrome, as the average emission level is
equal to or less than 2.5 m/s²
