I ran the trencher for 10 minutes with no slowdown. I tried the breaker again. The breaker just came from the repair guy (who is not a breaker service tech) (non in town), and he had it working for several minutes with only about 500 psi. I took it home, hooked it up and after 5 min of good work, it started to slow in in 15 seconds, no more hammering. Based on working with the trencher, the Bobcat flow and pressure seem satisfactory even if not a lot. But it boggles my mind that if the hammer works at partial throttle, why does it all of a sudden want to quit? Or is a hammer sensitive to flow and pressure and while it works for awhile, will it then overload it internally? BTW, based on it working at the hyd shop, there must be nitrogen in it and he did recharge on an earlier visit. Thanks for any ideas.</p></blockquote><p></p>
