My ERC040 Electric has started knocking when I start the hydraulics. By knocking I mean that when the hydraulic motor starts, it pops hard - like a whack with a hammer. As soon as the motor comes on - BANG - but if I operate the hydraulics quickly, there is no knock after the initial knock, provided I don't let the motor rest too long (let the pressure drop too much).
I suspect there is some kind of adjustment that softens the startup, such as an initial pressure relief on motor start. I think the motor is currently supplying 100% hydraulic pressure immediately on start. It used to start smooth and quiet. Has anyone adjusted this setting and can you tell me where it is if you have? Thanks in advance.
