N IL | We have a 2010 4730 with 90 foot booms, and 400 hours on it. Recently it seems that the boom fold keeps getting slower and slower when the pump is still on. It is visibly faster when I shut the solution pump off. Is this normal. Also, I just noticed that when I am sitting still and flushing with a set 40 psi, I have to rev the engine up to 14 or 1500 rpms to get the pressure up otherwise it is around 20 psi. Is this normal? I never had these problems until second pass of this year. TIA | |
