My 405 had been slightly bogging down recently and I found that the relief valve appeared to be sticking and not opening - is this something that happens now and then, or do these parts get worn and need replacing? I doused it with WD40 and it seems to have freed it up. Doesn't really mention any maintenance of that nature in the manual.
