4.0 FLUSHING DEBRIS
Debris in the water may get caught inside the nozzle. This trapped material will cause poor stream quality, shortened reach and
reduced flow. To remove debris trapped in the nozzle:
Shut off flow to the nozzle.
Move the stream shaper to the wide fog position.
Carefully unscrew and remove the nozzle's piston/cylinder.
• The cylinder is under about 25 lbs (11Kgf) of spring force. The spring must be
compressed to reinstall.
• A long white push rod is part of the cylinder assembly. Pull cylinder straight out until push
rod clears shaft.
• The cylinder and piston will come out as a unit.
• Remove the small spring and stainless steel poppet from the center of the shaft.
Remove debris.
Reassemble the nozzle.
Figures 5A, 5B & 5C show the pieces that are removed during the flush procedure.

Large amounts of debris may be unflushable and can reduce the flow of the nozzle resulting in an
ineffective flow. In the event of a blockage, it may be necessary to retreat to a safe area.
