2.4.3 Valve block
P1/P2: On-/Of drain
T/O: Lifting cylinder
C1/C2: Tilting cylinder
C3/C4: Sideshift/hydr. connection
Purpose of use:
The lifting mast can be equipped with an additional valve block so that the additional hydraulic function can
be centrally controlled and only two hydraulic connections have to be connected or disconnected in
attaching or taking off the fork lift mast. Connect lever (No. 69) on a double working valve of the tractor.
Commissioning:
Place the valve support (No. 65) in the tube provided on the outer frame. Connect the hydraulic hoses for
the various functions to the valves in pairs. Tighten the connections and swivels securely. Connect the inlet
and outlet hoses of valve block. Connect the inlet and outlet hoses of the valve block, taking care to use the
left hose (as seen in the driving direction) of the valve block as the pressure duct. It is imperative here that
the shortcuts are clean so that no dirt enters the hydraulic system of the machine.
When using a electro-hydraulic valve the switch should be mounted in such a position that the tractor driver
can access it easily from its operating position and make sure that the handle can't be confused with any
other controls to prevent unintentional operating.
Take care of the correct voltage of the tractor. The coil (no. 68) is only suitable for 12 volt. Connect a 2-wire
cable according to the diagram, consider adding an indicator light, fuse and / or socket on the circuit. Note: if
the valve block is placed in the tractor all hydraulic hoses factory performed are one meter longer than
specified in the parts list.
Manual:
Take care that the hydraulic hoses cannot become entangled. Take care that the operating handles cannot
become mutually entangled with other operating handles in order to prevent unintentional operating.
