Description of components:
1. Pressure relief valve
The valve is intended to reduce the
pressure when the implement lift is
forced down. Otherwise the imple-
ment can be damaged and the ma-
chine tends to move at the front.
2 and 3. Mechanically affected non-return
valve
Valves Ls and Aux1s have a little re-
turn leakage. To prevent movement
3
under the implements own weight, the
oil flow is stopped by these valves. To
2
allow oil flow when the implement is to
move in the blocked direction, the
valves are mechanically operated so
that they open.
4. Limit valve lowering
The valve is intended to reduce the oil
flow when the implement is lowered
which gives a lower lowering speed.
5. Collector block
The collector block collects all tramp
oil and return oil for further transporta-
tion to the tank.
