JLG 80HX+6:
JLG 80HX+6 Boom up and Extend functions will not work, Down and Retract ok

Hello All, my lift suddenly fails to raise or extend the boom. All other functions including boom lower and retract run fine.

I expect it may be a safety interlock issue.

What trouble would be common to just raise and extend, but not lower and retract?

Any advice greatly appreciated.
