I have not work with Kuhn hammer but I hawe a lot of experience of Beche´hammers.

I think you should look att the rubberseal round the bar.
If there is blowing air around the bar when its running,
i would say thats the problem, change the seal around the bar and
i think your problem will be solved.

If the hammer goes without oil in the two cylinder, the seal will be damage wery quickly.and there will bee a leak of air.
Oil line must goes in to the compressorcylinder to grease ewen the barcylinder.


I don think its the piston or the bar rings that failure.

Hope you anderstand my bad english
