pressure (6.0 mm Aq 0.2" in Aq) prevent external dust
from entering the cab.

also swing and hydraulic relief noise.

strengthened left and right side deck, aids vibration reduction
at the operator's seat.
Vibration at floor is reduced from 120 dB (VL) to 115 dB (VL).
dB (VL) is index for expressing
size of vibration.
