The hydraulic tank (5) is used as a collecting and suction tank for hydraulic
fluid, and is located under the operator's cab. The hydraulic pumps are con‐
nected to the suction connections (1) on the suction side. Hydraulic fluid
that flows back flows through the return filter (4) into the hydraulic tank, in
which process it is cleaned. A pressure switch/clogging indicator (3) moni‐
tors the level of contamination in the filter element.
The sight glass/thermostat (6) is used for checking the hydraulic fluid level
and the hydraulic fluid temperature.
The ventilation filter (2) is used as a vent for the hydraulic tank and as a
filler pipe.
