RECHARGE
Before proceeding to recharge any extinguisher, visually
examine the unit for any physical damage or impairment
which may further dictate the need for maintenance.
NOTICE
Extinguishers out of service for maintenance
or recharge shall be replaced by spare extin-
guishers of the same type and at least equal
rating.
To return the extinguisher to service after use:
NOTICE
If dry chemical is found on cartridge, this
indicates a bad gas tube. For gas tube
replacement instructions, refer to Gas Tube
Replacement Procedures on page 23.
1. Invert the extinguisher and open nozzle to clear dry
chemical from hose and to relieve all pressure remaining
in shell.

“E” Models (Metal cartridge guard)
– Place the hose
behind the push lever and insert the nozzle in the holder.
“G” Models (Composite cartridge guard)

place hose in nozzle holder or behind push lever as hose

3. Remove the cartridge guard and spent cartridge.
“
E” Models (Metal cartridge guard)

out.
“G” Models (Composite cartridge guard)
– Pull guard
out from the top until clip disengages from the cartridge

for left-hand and Part No. 77251 for right-hand threaded
