Hydraulics
Hydraulic Spool Block
Boom rest and fill pump are controlled by the valve
block mounted on the cross member of the chassis
under the cabin.
The solenoid valve blocks have various functions.
The directional valve controls oil flow to the desired
circuit. Each particular circuit can be identified by the
tag on the wires attached to the solenoids.
The double operated check valve blocks oil flow
through the solenoid when the solenoid is not
energised. This prevents that function leaking down,
for example if the right hand side of the boom
was tilted up the double operated check valve will
stop oil leaking through when the solenoid is de-
energised and lower the boom, preventing it moving
when the operator is not directing it.
The flow control allows the amount of oil flow to
the hydraulic circuit to be varied thus adjusting the
speed of that circuit. By turning the flow control
adjustment in, clockwise, the flow is reduced thus
reducing the speed at which that hydraulic function
will operate. By turning the flow control out, counter
clockwise, the flow is increased thus increasing the
speed of that hydraulic function.

Flow Control
Boom Fold
The pressure reducing valve is used to control
the maximum pressure in the Bi-fold circuit. The
pressure in the boom bi-fold cylinders determines
the suspension of the outer boom. If the pressure is
too high the boom rides too rigid and will not have
break out. If the pressure is too low the boom will
have low break out and tend to wave around. The
pressure in the bi-fold circuit should be between
1500 and 1700 PSI when the boom is in the folded
out, working, position.
