I have a Rammer S29 that gets occasional use. There seems to be a blanket of soundproofing ir something bbetween the outer and inner part. Its been slowly sliding down and covers up the ports for greasing. I chiselled out new ports so I could grease but of course it keeps sliding so covers them up again. Is this stuff performing any important function I wonder? The hammer is a "city" model and is supposed to be somewhat quiet. Im hoping thats all the blanket is for.Dont really care how much noise it makes.
Just to clarify,the S29 is an excavator mounted hydraulic hammer .I have it on a 15 tonne JD590D
