Hello I have a samsung SE130LCM with hydraulic issues. It has very sluggish tracking speeds it works under full for/rev direction but not when turning or mid range. Some times it well simply overload the pump and stall the engine. It has slow boom functions untill a second function is operated and if swing and bucket curl and boom movement is functioned it well load up and stall the engine. I'm looking for troubleshooting information or a manual. Looking for pressure settings and locations on the machine and what areas to install pressure gauges. It has a bucket and thumb. The filters have been changed with no signs of damage.
Good day Hydraulics rarely adjust themselves, the symptoms you are describing are most likely due to the engine low on power. If you can fit a flow - pressure meter, flow X pressure will answer what power the engine is making. Hope you find this helpful. Kind regards Uffex
