Oil pressure class scorpion loader

[Johno12345]

Have a class scorpion 7055 loader and find it very hard to realise the oil pressure when taking on and off the shear grab . Is there button or anything that must be pressed to realise the pressure or is it just a matter of moving the joystick when loader off like most other loaders ?

I don't know ow the machine so take this as you will

I guess there is a accumulator somewhere in the hydraulic circuit that has gone flat

Should be a button on left hand side of the boom near the carriage you can push to de pressurise them
