Volvo ECR28 Struggling to start after running

[andy85]

Hi I've got a Volvo ecr28 which starts fine and runs fine... but once it's switched off and started up again it really struggles to start like the hydraulics are under load. If you hold the blade down while starting it will just about get going but will be struggling to stay running until you start to use the hydraulics and then run fine a second after using the machine. It's as if the hydraulics are staying under load somewhere and the oil not freely returning to tank? I'm not terribly familiar with the hydraulics system and would like some advice or ideas on this issue please.
All filters replaced by the way and made no difference, battery replaced and no difference.
Much appreciated!

Does it have a pedal for the hammer lines?

I'd say the its stuck on ever so slighty

No pedals. Electronic switch on joystick.

They can stick too, I.E not centralised

Disconnect the joystick wiring to be sure

alternatively ... after turning engine off, with the ignition back on and dead man down, operate all control's motions and return to neutral ... see how it starts next time ... should dump any residual system pressure to tank

That is something I haven't thought to try. Thanks will give it a go!

Or long shot if you are not using a breaker, and it’s the aux circuit that’s the problem, I think the solenoid would be easy to find, pull the plug.
