A small filter before the cutting head protects the orifice. When it blocks or collapses, flow drops.
Safety first: Switch off the pump, release all pressure (open the on/off valve or bleed-down valve) and lock out before you open any high-pressure part. Never put a hand or tool near a running jet.
