Service Guidance: Complete the manufacturer's pressure-relief procedure and isolate the power source before servicing. Confirm 0507662 in the installed valve or main-assembly diagram. Titan's GPX 85 procedure describes driving the groove pin out of the valve handle, removing the handle and cam base, then reassembling in reverse order after valve service. Inspect the cam base, pin, attachment area, and valve mechanism before fitting the replacement. Address any binding or damage before installing a new knob. Follow model-specific instructions for knob alignment and retaining-hardware installation. Confirm proper PRIME and SPRAY operation using the manufacturer's procedure. Inspect for leakage without touching pressurized connections or fluid streams.
