2. Remove extinguisher from hanger or bracket whilst ensuring all mounting hardware is properly
installed, secure and in good operating condition. Check for damage or corrosion, abrasion, dents,
or weld damage or use of substitute parts. If any damage is found, hydrostatically test in
accordance with instructions in CGA C-1 and C-6 and NFPA 10.
NOTE:
Only factory replacement parts are approved for use on Victory fire
extinguishers.
3. Clean extinguisher to remove dirt, grease, or foreign material. Check to make sure that the
instruction nameplate is securely attached and legible.
NOTE: When cleaning, avoid use of solvents around the pressure gauge. They could
seriously damage the plastic gauge face.
4. Weigh the extinguisher and compare with weight printed in the "Maintenance" section on the
nameplate(label). Recharge extinguisher if weight is not within indicated allowable
tolerances. Any extinguisher not falling within the tolerance limits shall be properly
recharged.
5. Check the date of manufacture stamped on the extinguisher cylinder, dome or shown on
nameplate. The cylinder must be hydrostatically tested every five years to the test pressure
indicated on the nameplate. Never place an extinguisher back into service if hydro test is overdue.
Always complete hydro test and if acceptable return to service. Only refill with deionized water
with conductivity of less than 1.0 us/cm after successfully completing the hydro test. Non
deionized water will invalidate the class C capability. Do not mix deionized water with
non-deionized in extinguisher content.
6. Visually inspect the pressure gauge:
a. If bent, damaged or improper gauge, depressurize and replace.
b. If pressure is low, check for leaks and immediately correct any defects before pressurizing.
c. If over pressurized (overcharged), depressurize the extinguisher and follow recharge
instructions.
7. Check ring (safety) pin for freedom of movement. Replace if bent or if removal appears
difficult.
8. Inspect discharge lever for any dirt or corrosion which might impair freedom of movement.
Inspect carrying handle for proper installation. If lever, handle, or rivets are damaged replace
with proper Victory part(s).
9. Remove hose assembly and visually inspect inside valve body. Inspect nozzle and the hose
assembly for damage – replace, as necessary. Blow air through hose assembly to ensure passage
is clear of foreign material or obstruction.
10. Inspect the valve assembly for corrosion or damage to hose thread connection. Replace valve
assembly or component parts as necessary following the proper depressurization and recharge
procedures. If valve removal is necessary, complete all steps in the Recharge Procedure.
11. Install hose /wand assembly. Ensure coupling is firmly tightened into valve and place lance inside
two loops on the straps at the top and bottom of the cylinder. See appendix A for image.
12. Install new tamper seal and record service data on the extinguisher inspection tag.
13. Replace the extinguisher on the wall hanger or in the vehicle bracket making sure that it fits the
bracket properly and the bracket is securely attached – replace the bracket if necessary.
