Before mounting

• We always recommend thoroughly inspecting and cleaning the cylinder before installation and slightly smoothing the ports in the cylinder with 1000-grit sandpaper to remove sharp edges. This significantly extends the lifespan of the cylinder/piston. You can also refine or optimize it with a file or a multi-tool (Dremel) for even better performance.
