NOTE:

1. Sound pressure is a weighted measure. It is measured atthe operator's ear position while the walk-behind PSH isoperating at full throttle on concrete in a manner most oftenexperienced in “normal” circumstances. Sound pressuremay vary depending upon the condition of the concrete.Hearing protection is always recommended.

Figure 1. PORTO-SCREED PSH Dimensions

2. The vibration level indicated is the maximum RMS (RootMean Square) value obtained at the handle grip whileoperating the walk-behind PSH on dry sand in a mannermost often experienced in “normal” circumstances. Valueswere obtained from all three axes of motion. The valuesshown represent the maximum RMS value from thesemeasurements.
