Chemical injector

The nozzle, check valve, valve seat, and needlevalve may be cleaned by disassembling the chemical injector if clogging occurswithin.

As with any injector,if thespray tip becomes clogged or if downstream restriction increases in any manner, the injectorwill stop drawing chemical:The restriction should beeliminated before continuing.

A retaining spring (17) has been installed at the factory to prevent the adjustment knob (15) from being unscrewed too far and the internal parts from falling out.This spring can be removed if the injector needs to be taken apart for cleaning. Be sureleaveto spring in place whenever the pressure washer is being used. Removal of spring will 'not improve chemical flow but could cause chemical injector to quit working.
