One thing I forgot sorry about that. u must check if the ram hammer is wet from oil if not may be that is the reason. last year I was demonstraiting in STIA with two anyang hammers and I know them very good. philip of chaina if u know nothing about air hammers do not advice what to do with them. and u do not have to humiliate some one for his language, my English is also not good !!!

Trattoclip the small bolt with the hole in it and a cut for the screwdriver is a part of the nonreturn oiling valve that was unscrewwed from the vibratin and fell into the machine. if u''ll dissmentle the oiling pipe and unscrew the nonreturenvalv u''ll fined were it came from. to day they are producing new nonreturn valvs that u may ask your agent to get for u. as for the none regularity of the hammer work, check the handle of manual forging on the right side of the hammer(chrom plated) there under is a spring loaded lach sometimes 1 the spring is not holding the vibration and slides dowen and the handl that holds the valv is not in place. 2 the lach is having a step to hold the two valvs in a possition some times one must grind 1-2 mm and make the step deeper and the machine will start to forge in the right rhythem again. hope it helps Hofi
