We introduced the following technologies to reduce noise from our major power equipment released in fiscal 2004.

Through such measures as reducing the engine’s mechanical noise, we reduced the noise of the FF500 by 5 dB compared with the noise of comparable model (FU650) which has a similar output level.
The noise level is 82 dB(A), meeting the European noise regulations for 2006 (stage 2) criteria.

We have adopted the Noise Prevention Shroud and Intake and Exhaust Chamber System, which smoothes airflow and greatly reduces the intake and exhaust noise, in order to reduce the engine’s mechanical noise and intake/exhaust noise. In addition, an eco throttle contributes to further reduce noise effectively. As a result, the noise level was reduced by approximately 9 dB(A) (at 1/2 the rated output) compared with those of previous models*.
