E-One HP105 Trouble??

[Neal_HP105]

Our department has an HP105 that is about 5 years old. The problem is the ladder interlock system. Day to day checks of the system generally work, but on occasion the system has to be reset in order to transfer the hydraulics from the jacks to the ladder. E-One has worked on the problem by replacing the control box, it will work fine for a while, then it starts all over again. And now on several occasions it has failed and needed to be reset on the fire scene,(sometimes reseting more than once). My question is do any of you operate the same type of truck and are you having similar problems?? What have you been able to do to remedy the problem? Thanks for your assistance.

We have a 105 HP and it has had the same problem. We have also had a problem with only one underslung jack comming down when we switch to ladder. I know E-One has worked on it but don't know all of the details. It's currently OOS with a bad pto pump.

Sorry I couldn't be more help
