12.2 AUGER CIRCUIT PRESSURE ADJUSTMENT
IMPORTANT!
The auger valve relief is a load sense relief only and is used to limit the max load sense signal to the pump
compensators. This relief is set lower than the pump pressure compensator to allow the mix auger to continue
to operate when boom, chute and swing functions are at max load sense pressure.

To set the max pressure on the mix auger circuit loosen the
lock nut using a 13mm wrench and turn the load sense
relief all the way in using a #4 Allen key.

Loosen the lock nut on the auger pump pressure
compensator using a 13mm wrench.

With the chute tilt cylinders bottomed out adjust the auger
pump pressure compensator to 3900psi using a 3mm
Allen key. Release chute tilt function. Tighten the lock nut.

With the chute tilt cylinders bottomed out again adjust the
load sense relief until the pressure reads 3600psi.
Release chute tilt function. Tighten the lock nut.

The load sense relief valve setting is now 300psi lower than
the pump compensator pressure.

With auger pump functions all off. Set pump standby
pressure to 320psi by loosening the lock nut on load sense
compensator with 13mm wrench and adjust with 3mm
Allen key.
