Tilting the cab on my MC-600 Pumper

[bubbas08srt]

Hello, I have an '88 Mack MC-600 fc pumper has been running like a champ for the last year, has had regular service at the dealership. but now I am feel a little stupid i havent seen them or found out how to open the cab over..I have searched relentlessly for how to's, the old manual can't find the answer. Do i just keep pumping the jack till it goes up or is there a release that is holding it from going up, the pump works cause when i flip the switch i can hear all the pressure being released in the pump. Any help would be greatly appreciated

there is not a safety latch preventing from going up just shear push power of the jack.i thought maybe since it was cold the jack fluids were acting funny, but.it finally came up.only after.i called the dealer... they said keep jacking but apply the safety stand after its full upright. check ..thanks anyway

Just make sure you remove any loose items that could "launch" when the cab is raised. I saw someone put an SCBA through the windshield of a C cab Ford when he raised the cab without removing the SCBA from the officers seat.
