    Change the power curve on the EW180C

    Guys, is it possible to change the power curve of the pump on the EW180C? It goes from almost not operable on 1320rpm to beast mode on 1450rpm. It 's one click on the rotary switch. The mha on the pump solenoid goes from 350 to 80. Any idea if the Volvo Vocom would let me adjust the curve?

Today I had to go to "turtle" so I could finish the same route. Boom before the pump and MCV service was the only really...

    VOLVO EW180C issues after pumps and MCV service and rebuild

    @Ben Witter really appreciate your reply brother! Any advice will be super helpful. I 'm waiting for a kit of gauges, so I can take my measurements. I 'm pretty sure that not a single one of the functions, or even the combination of them is able to put the engine in stall. I think the max rpm...

    High engine oil temp warning EW180C

    Hey guys, the last week the excavator has triggered twice a high temperature warning. The common thing between these 2 warnings is that it happened after a 10-15km journey course when the machine stand still on a traffic light and not while operating. What could probably be wrong? Radiators are...
