5.1.5 Increasing the operating pressure
With the "Increase operating pressure" func-
tion, the hydraulic pressure can be increased
from 320 to 360 bar. This may be necessary
for heavy-duty work. To increase the pres-
sure, press the pushbutton (130/5) on the
right-hand four-way control lever. The function
only takes effect while the pushbutton is held
down.
The pressure increase affects the boom and
dipperstick only.
