Скачать или смотреть Pierce Ascendant Midmount Level-Assist issue? on slope/grade.

Following operator’s manual instructions of extend stabilizer beams fully, lower middle jacks independently until “Firm On Ground” light illuminates for each (beeping will stop each time), then hold “Level Assist” button until all jacks are set (and beeping stops once again). It’s supposed to level side to side for slope, deploy front jacks, then deploy rear jacks and adjust accordingly for grade.

It appears to adjust the middle jacks for slope but continues extending them out until it’s nearly teetering on the middle jacks. When it lowers the fronts they don’t even touch. When it lowers the rear you can see the cab bounce from the stress in the frame.

2 degrees grade, 2.7 degrees slope FYI.
