Questions and answers
I put a new limit switch on the outrigger legs , while the legs were down , and now when hit the controls to retract, it won’t , it just keeps raising three legs all loop sided
The JLG T350 will not retract the outrigger legs after installing a new limit switch if the boom is not fully retracted or not fully lowered into the transport position. The troubleshooting steps indicate that the boom must be completely telescoped in to close the telescope limit switch before the outriggers can be stowed. Additionally, the boom transport limit switch must be closed by lowering the boom into the transport position. Check if these conditions are met; otherwise, inspect the new limit switch for proper installation and functionality.

@Mr. Anderson thanks , but I figured it out myself, I clamped all the limit switches like the would have been in the retracted position, and then I was able to retract all the legs back in their up position
Unit has a 110 outlet near the bucket. Trying to figure out how do you get power to that outlet. When it’s plugged into the charger, there’s no power that’s the only place I see to plug anything in.
