got a used furukawa hydraulic breaker HB20 used on a 220-6 komatsu excavator, on the main valve body of the breaker there is an adjusting bolt called the valve adjuster and looks like someone already change its original position. I've noticed some punch mark on the body, the lock nut and the bolt and I wanted to know how many turns from seat position should I CCW turn this bolt. The bpm adjusting bolt on the side of the breaker still factory adjusted. Wanted to know how to adjust the valve adjuster position to get the maximum power from the breaker, thanks
