After use
WARNING
!
Do not remove the equipment until in safe area, clear of hazard.
CAUTION
!
Do not drop or throw down equipment as damage could occur.
1. Loosen the face mask straps.
○

face is broken, press the reset button (Fig 2, Item 2) to switch off
the valve.
2. Remove the face mask and fully extend all of the straps of the head
harness.
3. Fully close the cylinder valve.
4. Press the front button (Fig 5) (fold back the rubber cover to press the
button and then immediately refit the rubber cover) to fully vent the
system.
5. Remove the lung demand valve from the face mask (Fig 11 – push-in
coupling shown).
6. Open the waist belt buckle, lift the shoulder strap buckle to loosen the
harness and then remove the equipment.
7. Carry out the after use maintenance tasks in the maintenance table
(see Section 5.1).

Troubleshooting
The troubleshooting guide shows fault diagnosis and repair information
applicable to breathing apparatus users. Further troubleshooting and
repair information is available in Instructions for Use supplied with
associated equipment (e.g. face mask and air cylinder).
Contact service personnel or Dräger when the remedy information
indicates a service task, or if the symptom remains after all remedy actions
have been attempted.

Maintenance
5.1
Maintenance table
Service and test the breathing apparatus, including out-of-use apparatus,
in accordance with the maintenance table. Record all service details and
testing. Refer also to the Instructions for Use for the lung demand valve,
face mask and other associated equipment.
Additional inspection and testing may be required in the country of use to
ensure compliance with national regulations.
Daily check – If the PAS Colt is held in a ready-for-use condition, check
daily that the pointer of the cylinder pressure indicator is inside the green
area. Charge the cylinder if it is in the red area (see Section 5.2.2).

Notes
Dräger recommendations
1. These maintenance tasks may only be carried out by Dräger or trained
service personnel. Details of the tests are contained in the Technical
Manual which is issued to service personnel that have attended a
relevant Dräger maintenance course.
2. Lightly lubricate the O-ring of the lung demand valve (A-type coupling
only) as required (recommended lubricant is Dow Corning
Molykote 111 Valve Lubricant and Sealant). Products other than the
recommended lubricant are not tested and may damage the
equipment.
3. Replace the sintered filter if a drop in reducer performance is observed
during a flow check or if it is visibly damaged.
4. Replace the high-pressure connector O-ring if it is found to leak during
functional testing or if the O-ring is visibly damaged.
5. Where the breathing apparatus is subjected to a high level of use (in
training establishments etc.), reduce the overhaul period for the
pressure reducer. In these circumstances, Dräger recommend that the
overhaul frequency should be less than 5,000 applications of use. An
application of use is defined as a single use of the fully assembled
breathing apparatus, where the user breathes from the air cylinder. It
does not include system pressurization for pre-operational checks.

Maintenance tasks
5.2.1
Removing the cylinder
WARNING
!
High-pressure air release may cause injury to the user or other
personnel near the breathing apparatus. Close the cylinder valve
and fully vent the system before attempting to disconnect the air
cylinder.
Remedy
1. Close the cylinder valve and press the front button (Fig 5) (fold back

and retest
2. Disconnect the cylinder valve from the pressure reducer.
Substitute user
3. Carefully remove the cylinder from the holster. To prevent damage,
replaceable accessories
ensure that the hand wheel of the pressure reducer remains clear of
and retest
the cylinder.

5.2.2
Air cylinder charging
WARNING
!
Air quality for compressed-air cylinders must conform to
Service task
requirements of EN 12021.
●
Refer also to the instructions supplied with the cylinder and the
charging unit for recharging the cylinder.
●
Only charge compressed-air cylinders which:
○
Conform to national standards.
○
Feature the original manufacturer's test date and test mark.
○
Have not exceeded the test date indicated on the cylinder by the
last testing station.
○
Are not damaged.
●
To prevent ingress of moisture into the cylinder, ensure that the
cylinder valve remains closed until connected to the charging unit.
●
Recharge to the rated working pressure of the cylinder. Dräger
recommend a charge rate of 27 bar/minute (rapid charging will
increase the temperature resulting in an incomplete charge).
●
To prevent overcharging of the cylinder, Dräger recommend using a
pressure-limiting device on the charging compressor.

CAUTION
years
!
Cleaning agents and disinfectants listed below are not
manufactured by Dräger and have been reviewed only for
compatibility when used to clean or disinfect the subject Dräger
product(s). Read and comply with all safety precautions provided
by the manufacturers of such agents and disinfectants.
Do not exceed 30 °C for washing, disinfecting and rinsing
solutions. Do not exceed 60 °C for drying, and remove
components from the drying facility immediately when dry. Drying
time in a heated dryer must not exceed 30 minutes.
Do not immerse pneumatic or electronic components in cleaning
solutions or water.
If water is trapped and then freezes inside the pneumatic system
of the breathing apparatus (such as the lung demand valve),
operation will be impaired. Prevent any liquid from entering, and
thoroughly dry the breathing apparatus after cleaning to prevent
this from occurring.
Refer also to the Instructions for Use for the lung demand valve, face mask
and other associated equipment.
Cleaning and disinfecting materials:
●
Cleaning agents – Sekusept (concentration: 0.5 % – 1 %) or
Safetywash (concentration: 0.7 %)
●
Disinfecting agents – Incidin Rapid (concentration: 1.5 %) or
Safetywash (concentration: 20 %; meets the requirements of
EN 13727:2012 as a bacterial disinfectant)
●
Use only clean lint-free cloths

Instructions for Use
i
1. Prepare cleaning solution as per manufacturer's instructions. Clean
the breathing apparatus manually using a cloth moistened with
cleaning solution to remove excess dirt.
2. Prepare disinfecting solution as per manufacturer's instructions. Apply
to all internal and external surfaces, ensuring that all surfaces remain
visibly wet for 15 minutes.
3. Rinse all components thoroughly with clean water to remove all
cleaning and disinfecting agents.
4. Dry all components using a dry cloth, in a heated dryer or in air.
5. Contact service personnel or Dräger if disassembly of pneumatic
components is required.

Storage
6.1
Storage preparation
●
Extend the shoulder straps, waist belt and the straps of the face mask.
●
For storage, place the face mask in a protective bag (contact Dräger
for supply of a suitable bag).
●
Route rubber hoses in such a way that the bend radius is not too acute
and the hose is not stretched, compressed or twisted.
6.2
Storage conditions
●
Store the equipment between -15 °C and +25 °C. Ensure that the
environment is dry, free from dust and dirt, and does not subject the
equipment to wear or damage due to abrasion. Do not store the
equipment in direct sunlight.
●
Fix the breathing apparatus securely to any raised mounting point to
prevent it from falling.
