DANGER!
For AC sawmills it is recommended that a 30mA Ground
Fault Interrupter (GFI) be used.

The noise level measurement was taken in accordance with
PN-EN ISO 9612 Standard.
TABLE 1-7
1. The noise level measurement was taken in accordance with PN-EN ISO 3746 Standard.
The noise exposure level given above concerns an 8-hour work day.Value for associated uncertainty
K=4dB.
2.The measured values refer to emission levels, not necessarily to noise levels in the workplace.
Although there is a relation between emission levels and exposure levels, it is not possible to
determine with certainty if preventives are needed or are not needed. The factors affecting a current
level of noise exposure during work are inter alia room characteristics and characteristics of other
noise sources, e.g. number of machines and machining operations nearby. Also, the permissible
exposure level value may vary depending on country. This information enables the machine’s user to
better identify hazards and a risk.
