yeah me too exactly. first I have to keep pressure on the bit in other words keep the bit in contact with the work. second short frequent low RPM bursts. if The motor RPM gets Even a third or halfway up to Max then the hammer part can't catch up. I was thinking there was a missing or broken return spring or maybe just the piston is shot. maybe some sort of fouled up reed. valve I checked and there are no replacement parts or piston rings available.
