Steve, I have seen several spec"s sheets on many types of breakers and have never seen the blow impact,just the same as you won"t see the compression of a diesel engine,the gas is nitrogen,the accumulator on the Montabert never leaks unless the diaphragm is punctured,then it has to be changed,it is service centre job,the diaphragm is like that you would see in the brake chamber of a truck,the snag with the Montabert is you have to have special equipment to fill it with nitrogen,most other breakers you can do it yourself it is as simple as pumping a tyre,usually what is done is you remove the accumulator and take it to the shop,to remove it you only remove every second bolt,ie the accumulator is in two parts with the diaphragm in between,short bolts hold the unit together and the longer bolts hold it to the cylinder,if you got the return pipe pulsing badly it is certain that gas is gone,if you have the same size pipes on both make sure that the feed is to the feed etc,I"v got lots of very expensive gauges and flow meters ect as I am in the business but if the breaker is working properly you know in two seconds by the chatter coming from it without any clocks.
