2.6 HIGH PRESSURE RELIEF VALVE
The high pressure relief assembly enables the use of
hydraulic implements. One circuit from pump activates
hydraulic raising and lowering. The other controls the
power steering.
A high pressure relief assembly should be used when
both the 3-point linkage and the auxiliary hydraulics
are required. To use the auxiliary hydraulics, turn the
directional valve clockwise and connect the implement
hydraulic hose to A, B, and C ports.
When you don’t use auxiliary hydraulics, be sure to
turn directional valve counter-clockwise completely.
If not, the relief valve will operate.
