In cooperation with stone masons and sculptors, as well as scientific institutes F+K have developed a product to meet ergonomic requirements. Ergonomics: ie. optimal working and handling design, the use of thermally-insulated materials kind to the skin and a vibration and noise-suppressing construction. F+K hammers “lie nicely in the hand”.Percussion impact regulation separately pre-selected at the air inflow with infinitely variable regulator. In whatever setting, whether low or high, the function of the air intake valve is in no way limited.

Different percussion characteristics:
Owing to the different steering systems there are lower percussion rates, but with a higher individual impact performance on the F+K preciso-SE series and a higher percussion rate and a somewhat “softer” impact on the F+K preciso series.

Starting:
Reliable and exact control, so that mistakes due to uncontrolled hammer impact cannot occur. This function has been especially perfected on the chipping hammers in the F+K preciso-SE series thanks to the sliding-valve steering.

Three performance classes:
There are 3 hammers in each of the product series F+K preciso and F+K preciso-SE. In each case the different piston weight (Æ) and/or the piston stroke are the decisive factors in performance.

Easy care and maintenance construction:
All our hammers can be dismantled and reassembled without the use of tools. Care and maintenance, especially precautionary maintenance help to save costs and improve the readiness for working. Many parts are exchangeable.
