If he starts it and lets it idle it can idle all day and he can use the bucket and drive systems as long as it does not exceed a fast idle everything is fine. If the throttle is advanced within a minute or less it will show a hydraulic pressure code, a buzzer will sound and shortly the machine will shut down. It can be restarted right away with no problem unless you advance the throttle. I believe it is either a sensor problem or else pressure is building in the system. He thinks it is electrical and has taken the boss box off, drilled it open and had it checked out. It was fine. I have gone thru the archives here and did not see anything similar. As far as I can see there are no hidden filters and the machine does not have the case drain filters that some have. I will have to say though, the archives do have a lot things that have been helpful with my own 632. Thanks in advance for any ideas. jerry</p></blockquote><p></p>
