Elkhart Brass SFL-BG (RNZN) - Manual (Page 5)

Maintenance
Weekly visual inspections and monthly operational inspections should be exercised in order to ensure reliable
operation. These inspections may be done on a daily basis depending on the needs of the user. All nozzles
should be flow tested before entering any hazardous area to ensure equipment is operating properly.
If the nozzle tip is not functioning correctly, it may need to be re-greased. This can be done by removing the
detent screws (19), then removing the tip (20) from the nozzle. These parts can be seen in the following
assembly drawing. Clean the acme threads with a rag then generously apply silicone grease (Climax #66111) to
the acme threads. Reassemble the nozzle tip to the center barrel and clean excess grease from the nozzle.
If the shut-off handle begins to operate to easily, the adjustable seat (7) may need to be tightened. This can be
done without disassembling the entire nozzle. Remove the set screw (24) from the nozzle body. After this is
done the pistol grip (28) can be removed from the nozzle assembly. These parts can be seen in the following
assembly drawing. Use an Elkhart Brass Seat Wrench (P/N 71251000) to adjust the seat until the desired
tightness is achieved. Reassemble the nozzle. Be sure to apply thread locker (Loctite #242 or equivalent) to the
set screw before reassembling.
