PROCEDURES FOR SERVICING THE BLAZEX RANGE OF HAND PORTABLE FIRE
EXTINGUISHERS
Introduction
The commissioning and servicing of fire fighting equipment must be carried out by a
competent person using the correct tools to follow these manufacturer‟s instructions and
any National standards required in the relevant Country.
This maintenance should be performed at least annually. The extinguishers should be
visually inspected at least quarterly, but preferably monthly, by the user, to ensure that
the equipment is in its designated position, has not been used and has not been
tampered with.
In the event that an extinguisher cannot immediately be rendered suitable for continued
service, it must be marked 'NOT MAINTAINED' until it can be repaired/recharged.
The competent person must advise the user of any equipment, which is either
condemned or unfit for service and make any recommendations for replacement and/or
remedial work.
Always check the security and suitability of the hanging bracket, and that the
extinguisher is of the right type for the prevalent risk.
If the extinguisher is to be sited in a hazardous/corrosive environment i.e. marine use,
the inspection periods should be more frequent. The effects of the environment should
be considered, with particular reference to corrosion and legibility of marking
instructions. If there is significant corrosion or the markings are not legible, then the
extinguisher should be withdrawn from service.
It is essential that extinguishers are not subjected to temperatures outside of the
temperature range stated on the extinguisher.
Extinguishers should remain in their allocated location, and should be used only for the
purposes of extinguishing a fire. On no account should the extinguisher be removed for
any other purpose, and should not be subjected to any impact, force, heat, abrasion or
any other misuse or condition that may be detrimental to the integrity of the extinguisher.
Fire extinguishers are life saving appliances and as such, need to operate correctly, in
the event of a fire. They must not be used as toys.
Failure to use the recommended spare parts and adhere to these maintenance
instructions may cause the extinguisher to malfunction or prevent it from operating
altogether. This may invalidate the warranty and the manufacturer accepts no liability in
the event that these instructions are not followed.
Care must be taken to ensure that residual media (powder and foam) are disposed of in
accordance with environmental legislation. Where facilities exist, condemned
extinguishers and components should be recycled.

SERVICING PROCEDURES FOR BLAZEX RANGE
STORED PRESSURE POWDER MODELS
MODEL NO'S: XAS6, XAS9
1. Remove extinguisher from hanging bracket and check security of the bracket,
rectify if necessary. Check exterior of extinguisher for corrosion or damage, if
found, mark the maintenance label as “CONDEMNED” and withdraw from
service.
2. Ensure safety pin is in position and the extinguisher has not been completely
or partially discharged. If the extinguisher has been completely or partially
discharged, discontinue servicing procedure and commence recharge
procedure (Ref. RPBP).
3. Ensure instruction label is legible, rectify as necessary. Check for
damage/corrosion to extinguisher body. If significant damage/corrosion is
found, mark the extinguisher as condemned and/or remove from service.
4. Checkweigh the extinguisher against the gross weight recorded on service
label. If underweight by more than 10% of contents, the extinguisher should
be removed from service and recharged. Invert extinguisher to loosen
powder.
5. Check safety pin for free removal. Replace pin and fit new seal (in
accordance with service colour code).
6. Check pressure gauge is reading 12 bar (@+20ºc) in the green zone. Check
that gauge is operational by using magnetic gauge test kit; ensure that after
testing the needle returns to the original mark. Fit new gauge sticker. If a
deviation of more than 10% is recorded, remove extinguisher from service
and recharge.
7. Remove discharge hose and blow through. Check discharge hose, nozzle
and clips for wear, cuts or abrasion. Replace as necessary. Fit new „O‟ring to
hose assembly and refit hose.
8. Fill in details of service, including extinguisher weight, on service label using
indelible pen. Clean extinguisher and return to service.

RECHARGING PROCEDURE FOR BLAZEX RANGE STORED PRESSURE DRY
POWDER MODELS
MODEL NO'S: XAS6, XAS9
THESE RECHARGE PROCEDURES SHOULD BE USED IF COMPLETE OR
PARTIAL USE OF THE EXTINGUISHER IS SUSPECTED
1. Check for signs of damage or significant corrosion to extinguisher. If found, do
not continue recharge procedure, mark extinguisher “CONDEMNED” and inform
user. Ensure instruction label is legible, rectify if necessary.
2. Ensure pressure is relieved by inverting extinguisher and squeezing the levers
together slowly (whilst pointing nozzle down and away).
3. Remove hose and loosen headcap, using Blazex bar adaptor. (do not use
incorrect fitting spanners). Remove headcap slowly, allowing residual pressure to
escape through vent slots.
4. Empty residual powder from extinguisher body and discard.
5. Inspect the extinguisher inside, checking for caked powder or corrosion,
indicating moisture inside the cylinder, rectify or replace extinguisher if found.
6. Recharge the extinguisher body with new dry powder, ensuring correct quantity
and type. Never mix different types of powder as pressure and moisture
may develop as a result of a chemical reaction.
7. Remove syphon tube, tube holder, spring and spindle. Thoroughly clean any
residual powder from chamber using a soft brush or valve tool. Remove 'O' rings
from spindle, clean 'O' ring grooves and lubricate lightly using silicon gel. Fit new
'O' rings ensuring they are centralised.
8. Refit spindle, spring and tube holder to valve. Refit syphon tube. Fit new valve
'O' ring.
9. Clean cylinder neck threads and 'O' ring seat. Refit headcap, tighten using Blazex
bar adaptor.
10.With the valve open (depressed), pressurise through valve, to 12 bar (@
+20ºc) using dry air or Nitrogen, close valve (release) and shut off pressure
supply. Remove pressurising adaptor slowly, as a small amount of pressure
may remain in the filling line.
11.Refit safety pin and seal (in accordance with service colour code).
12. Fit new discharge hose „O‟ring and refit discharge hose.
13.Check for leakage. Record recharging details, including new weight on service
label.
