and see if the pressure increases again. Start with the last
function in the series first.

An increased pressure up to the compensator setting of the
pump (>3400psi) can indicate a mechanical blockage/jam of
that function or a sticking/stuck hydraulic valve.

To check pump pressure compensator setting you must plug
the inlet hose to the belt motor. Since, there are no
cylinder functions on the belt circuit there is no way to test
this setting otherwise (see belt circuit pressure adjustment).

The belt hydraulic manifold houses all the cartridge
valves that run the belt hydraulic circuit. Valve cables are
labelled to show valve function.
5.3.3 AUGER
IMPORTANT!
The auger hydraulic circuit is powered by the first load sensing piston pump that is referred to as the auger
pump. The auger circuit operates the mix auger, boom, chute(s), swing and chain oiler. All the functions
operate in parallel, so each one can run independently of the other.

When testing individual functions on the auger circuit
simply operate that function individually using the joystick
and/or keypad.

Checking pump max pressure settings can be done by
simply extending or retracted the chute tilt function to the
end of stroke.

The auger hydraulic valve is a sectional load sensing
directional control valve. If uses pilot operated actuators
for the mix auger circuit and direct acting actuators for the
boom, chute and swing circuits. All valve actuators have
manual overrides for testing and troubleshooting and
testing.
