I. Operating Instructions

A. The nozzle is put into operation by first checking that
the Nozzle Tip is in the Wide Angle Fog position and
the Horshu-Handle is in the “CLOSED” position.

1. Rotate the Nozzle Tip by grasping the Hand
Grip and turning it counter clockwise until the
bottom of the Locking Lever is resting in the
notch directly below the Wide Angle Fog symbol
on the Nozzle Tip.

2. Push the Horshu-Handle as far forward as

possible to place it in the “CLOSED” position.
B. The nozzle-man should activate the water supply.

slowly move the
Horshu-Handle from the “CLOSED” to the “OPEN”
position with the nozzle aimed in the direction of the
fire.

Slowly pull the Horshu-Handle as far back as

1.
possible to place it in the “OPEN” position.

E. The nozzle-man should then test the operation of the
nozzle by rotating the Nozzle Tip from the Wide Angle
Fog stream pattern position to the Narrow Fog position
and on to the Straight Stream position and then reverse
direction and go back to the Wide Angle Fog stream
pattern position. The nozzle-man should stop at each
stream pattern position long enough to inspect the
stream pattern. Each of the fog pattern positions should
produce a complete conical shaped pattern with no
gaps or disruptions. If gaps or disruptions are observed
in any pattern position the nozzle should be checked for
debris or damage (see Section IV).

CAUTION: The Nozzle Tip must be returned to the Wide
Angle Fog pattern position before preparing to advance the

hose team into an engagement with the fire.

F. The nozzle is now ready for operation. Refer to
Command Firefighting Doctrine for application.

II. Making Ready for Service

A. After each use the nozzle should be removed from
the hose while the hose is being drained and stored.
