Nozzle Operation
Flow Capabilities
This nozzle has been designed to exhibit the following flow characteristics:
• Maximum Working Flow 95 GPM (360 LPM) at a Maximum Working Pressure of 100 PSI (6.9 BAR)
Ball Shutoff
This nozzle has been equipped with a ball shutoff. The nozzle can be shut off by pushing the horseshoe handle
forward, away from the user. In order to open the shutoff, the handle should be pulled back toward the user.
These positions are indicated by CLOSED and OPEN lettering on the horseshoe handle. It is very important
to open and close the shutoff slowly to avoid a water hammer effect.
Pattern Adjustment
The total tip rotation of this nozzle is 306 degrees and can be adjusted by the following steps:
• A fog pattern can be achieved by rotating the nozzle tip to the left or counter-clockwise. If the nozzle
tip is rotated into this position the locking lever will be pointed to the
marking on the nozzle tip.
• A straight stream or jet pattern can be achieved by rotating the nozzle tip to the right or clockwise. If
the nozzle tip is rotated into this position the locking lever will be pointed at the marking on the nozzle
tip.
• A narrow fog pattern can be achieved by stopping the rotation of the nozzle tip at the detent in between
the wide fog and straight stream positions. The locking lever will be pointed at the marking on the
nozzle tip as a visual indication of this position. This position is characterized by a 45 degree fog
pattern.
Flushing The Nozzle
This nozzle has been equipped with a flush position for removing small debris from the water supply that may
become trapped in the nozzle. This debris may cause poor stream quality and reduced water flow capabilities.
If this occurs the nozzle needs to be flushed. The nozzle can be flushed by following these steps:
• Press the locking lever down until the front end rises out of the gallonage slot. Rotate the center barrel
to the left or counter-clockwise until the locking lever is pointed toward the FLUSH indication.
• After flushing the nozzle, be sure to rotate the center barrel back to the right or clockwise until the
locking lever is returned to the gallonage slot.
The nozzle should be flushed after each use to ensure that debris does not built up inside the nozzle. This
flushing method should also be used after flowing foam through the nozzle. If the debris is too large to pass
using this method, it may be necessary to shut down the hose line and remove the nozzle. Large debris can then
be removed from the base of the nozzle or from around the stem head.
