Always use ear protection!
When your machine is running, noise generated by the machine may come from the following:

Saw blade during cutting or material feed mechanism


Our products pass noise testing less than 78 dBA. Noise level vary according to working conditions
and we recommend ear plugs or other hearing protection at all time. If your machine produces an
undesirable noise while it is running, you should:
1. Make sure all maintenance tasks have been performed following the prescribed maintenance
schedule (Refer to Section 8).
2. If maintenance does not seem to solve the problem, follow the troubleshooting procedures
under Section 9.
CE COMPLIANCE
Cosen’s CE model is designed to satisfy regulations of the Council Directive on the approximation of
the laws of the Member States relating to machinery (2006/42/EC) ‐ Annex I Essential health and
safety requirements relating to the design and construction of machinery.
RISK ASSESSMENT
Risk assessment generally takes account of intended use and foreseeable misuse, including process
control and maintenance requirements. We made every effort to avoid any personal injury or
equipment damage during the machine design stage. However, the operator (or other people) still
needs to take precautions when handling any part of the machine that is unfamiliar and anywhere on
the machine that has potential hazards (e.g. the electrical control box).
