OPERATION
CAUTION: PERSONS EXPECTED TO USE THIS EXTINGUISHER SHOULD BE TRAINED IN INITIATING ITS OPERATION
AND IN THE PROPER FIRE FIGHTING TECHNIQUE. FAMILIARIZE ALL PERSONNEL WITH THIS INFORMA-
TION BEFORE AN EMERGENCY OCCURS.
1. Move the extinguisher to within approximately 25 feet of the fire site. REMOVE RING
(SAFETY) PIN.
Pull “T” handle to OPEN ARGON VALVE. This will pressurize the extinguisher.

PULL HOSE FROM RACK AND START BACK 15 FEET from the fire.
Note: When using the wand applicator START BACK 6 FEET FROM FIRE.
3. OPEN NOZZLE SHUT-OFF slowly by pulling handle fully towards you (hold the nozzle
firmly and be prepared for a discharge recoil). COVER ALL BURNING METAL WITH
POWDER.

SHUTDOWN
1. After making sure that the fire has been completely extinguished, push the nozzle lever forward to the CLOSED
position.
2. Close the Argon cylinder valve (push “T” handle to closed position).
3. Tip extinguisher over to rest on wheels and handle, then slowly open the nozzle lever again to clear the hose of
chemical agent and pressure (be prepared for recoil and discharge of agent).
WARNING: MAKE SURE THAT ALL PRESSURE HAS ESCAPED BEFORE FURTHER DISASSEMBLY.
4. Stand the extinguisher upright after complete depressurization.
Note:
Argon pressure in the agent cylinder cannot escape through a disconnected pressurizing hose due to a
check valve in the system. Always be careful when removing the fill cap.
5. Coil the extinguisher hose onto the storage rack and position the nozzle (and/or Extension Wand) onto the
mount in preparation for transport to the recharge location.
WARNING: THE SHIPPING CAP MUST BE INSTALLED ON THE ARGON CYLINDER PRIOR TO TRANSPORT
TO THE RECHARGE LOCATION.
INSPECTING THE EXTINGUISHER
I NSPECTION (NFPA-10 4.2.1) is a “quick check” that an extinguisher is available and will operate. It is intended to give
reasonable assurance that the extinguisher is fully charged and operable. This is done by seeing that it is in its
designed place, that it has not bee actuated or tampered with, and that there is no obvious physical damage or
condition to prevent operation.
