GENERAL
INFORMATION

Sound Pressure Level Information:
Sound pressure is “A” weighted . Measured at the operators ear position while the ride-on trowel is operating at
full throttle on concrete in a manner most often experienced in “normal ” circumstances. Sound pressure may vary
depending upon the condition of the concrete. Hearing
protection is always recommended.
Vibration Level Information:
The vibration level indicated is the maximum RMS (Root Mean Square) velocity value obtained at the handle grip
while operating the ride-on trowel on curing concrete in a manner most often experienced in “normal ” circum-
stances. Values were obtained from all three axes of motion. The values shown represent the maximum RMS value
from these measurements.
