Hello, I’m trying to tilt the cab on a Mercedes Actros Mp4 and when I start pumping the lock from driver side is not unlocking... I’m doing something wrong? Does anyone know how to unlock it?
Thanks!

Did you put the leaver on the pump all the way in( the small bar that is on the lift puns- push it towards the engine to lift, pull it out to lower cab), before it lifts you have to pump and pump till it makes pressure, if so check if you have ATF fluid in the cab lifting pump!!

Use wd-40 and a hammer, just be carefully

[GarryMr]

this is for lifting up
this is for lowering down

That guys, I will give it a try tomorrow

The pins seize. If the cab starts to lift but stops then release it back down, penetrating oil and prybar or a gentle hammer to free the pins/hinge.
