erything right you can still be killed or injured. None of the
models of Kirby Morgan helmets or masks can prevent acci-
dents, injuries or death due to improper training, poor-health,
improper supervision, improper job requirements, improper
maintenance or acts of God.

BCAUTION
Kirby Morgan Dive Systems, Inc. declines all responsibility for
accidents due to an incomplete understanding of the equip-
ment.
BCAUTION
This mask should be used only with breathing air meeting
requirements of EN132 standard, Appendix A.
NOTICE

ries which are approved according to EN250.
BCAUTION

NOTICE
In accordance with the EN250 standard, the maximum ap-
proved depth for the use of the equipment is 50 meters (164
feet).
BCAUTION
Never use a solvent to clean the mask. Never use aerosol
sprays on or around the mask as certain solvents and propul-
sion agents attack and damage rubber and certain plastics.
BCAUTION
In order to use this mask it is ABSOLUTELY NECESSARY that
you follow a training course and RECEIVE CERTIFICATION,
issued by a competent training organization, confirming your
ability to dive. Use of a mask by untrained and unqualified per-
sonnel is DANGEROUS and could lead to serious accidents,
and/or death. Use of this equipment by a person who does not
possess certification issued by an appropriate organization
renders void any guarantee, express or implied, on this prod-
uct. This mask, as supplied, is intended to be used for Scuba
diving.
Before each use the mask should be carefully checked and
submitted to the operational tests. NEVER DIVE with a mask
showing any signs of deterioration or which has a below nor-
mal performance.
NOTICE
The hoses tted to the EXO-26 Full Face Mask, and supplied by KMDSI,
meet the requirements of the EN250 standard concerning the connection
of components. Only origional Kirby Morgan hoses should be used as
replacements.

Use only silicone grease on the rubber components. Never grease the parts of your
mask with a lubricant containing hydrocarbons, household oil, or motor oil.
Before diving in cold water (water temperature below 10°C / 50°F), you should rst
obtain specialized training and certication in the appropriate techniques from a
competent organization. You should also use equipment intended for this purpose.
The use of a CE approved rst stage regulator with a silicone oil chamber will
reduce the possibility of rst stage icing causing failure. Also, the diver should
have been trained and have mastered the techniques of cold water diving so as to
be able to take all precautions necessary to avoid freezing of the regulator. All of
this is included in the training programs of organizations offering courses in diving
in cold water or under ice.
In order to reduce the risks of regulator freezing when diving in cold water (below
10°C), consider doing the following:
1 - Protect your regulators from any accidental ingress of water into the rst or
second stages.
2 -Protect your equipment from cold before the dive. More precisely, keep your
mask and all its accessories in a warm dry place.
3 - Carry out all pre-dive checks of your equipment in a warm dry place if neces-
sary, before even going to the dive site.
4 - Avoid breathing through the regulator or pressing the purge button in very cold
air before entering the water.
5 - As far as is possible, avoid excessive effort during the dive.
6 - Check that the air used to ll your cylinder is dry. The water vapor contained
in this air should have a condensation point below -54oC. Excess water vapor can
freeze, causing a free ow, or can block the air ow completely.

tive 89/686 of 21 December 1989. Testing procedures were in accordance with the

Chapter 1
EXO-26 Balanced Regulator Full Face Mask
1.1 Introduction
KMDSI has been designing and manufacturing SCUBA, commercial, scientic,
search & rescue, and military diving equipment for over fourty years. Many of
our products have become the standard of the industry due to their design, high
quality, and outstanding performance. The Balanced Regulator EXO-26 are part
of this continuing tradition.
NOTICE
This user guide gives the user basic daily operational information for the
EXO-26 Balanced Regulator Full Face Mask. For detailed maintenance and
use information, please refer to the EXO-26 Operations and Maintenance
Manual, KMDSI part # 100-030.
The following is a list of features to be found on the Balanced Regulator EXO-26:
1) Fully Adjustable Regulator:
The regulator is fully adjustable over a wide range of operating pressures. By
simply turning the Adjustment Knob while diving, you can “tune” your regulator
for your type of diving.
2) EXOthermic™ Exhaust System:
The regulator assembly in the Balanced Regulator EXO-26 isolates the intake and
exhaust chambers from one another. The diver’s own breath assists in reducing
thermal drain by warming certain areas of the regulator. This helps to eliminate
freeze ups in cold water diving.
3) Earphone Pockets:
The earphones are allowed to equalize because all interior parts of the mask share
a common cavity. There is never a need to adjust their position and they are easily
accessible.
4) EXOskeleton:
The outer frame, or EXOskeleton, serves several functions. It protects the face
seal and is used to mount external components, such as the regulator, lens, and
communications.
5) Suspension Face Seal:
The suspension area of the face seal is attached to the EXOskeleton by ve mount-
ing legs, much like a trampoline. In this way, the seal allows the face to seal on a
