Part Numbers

The ordering codes for the Compact MINI Spray Gun are:

COMM-HS1-10 Compact MINI HVLP 1.0

COMM-HS1-12 Compact MINI HVLP 1.2

COMM-TS1-10 Compact MINI Trans-Tech® 1.0

COMM-TS1-12 Compact MINI Trans-Tech® 1.2

COMM-RS1-08 Compact MINI Round Spray Trans-Tech® 0.8

Operational Description

This Compact MINI Spray Gun is a professional quality gun designed with both high volume, low pressure
(HVLP) technology or Trans-Tech® technology. HVLP Technology reduces overspray and limits air cap
pressure to 0.7 bar (10 psi) (complies with rules issued by SCAQMD and other air quality authorities). Trans­Tech technology, will obtain transfer efficiencies above 65%.

IMPORTANT: These Sprayguns are suitable for use with both waterbased and solvent based coating
materials. These guns are not designed for use with highly corrosive and/or abrasive materials and if
used with such materials it must be expected that the need for cleaning and/or replacement of parts will
be increased. If there is any doubt regarding the suitability of a specific material, contact your DeVilbiss
Distributor or DeVilbiss direct.

NOTE: This gun is not to be used with halogenated hydrocarbon solvents or cleaning agents such as
1,1,1,-Trichloroethane or methylene chloride. These solvents can react with the aluminium components
used in this gun and cup. The reaction can become violent and lead to an equipment explosion.

SAFETY PRECAUTIONS

This manual contains information that is important for you to know and understand. This information relates to USER SAFETY and
PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the following symbols. Please pay particular
attention to these sections.

CAUTION

Important information that tells how

Important safety information – A hazard
that may cause serious injury or loss
of life.

to prevent da mage to e qu ipment,
or how to avoid a situation that may
cause minor injury.

The following hazards may occur during the normal use of this equipment.

Please read the following chart before using this equipment.

HAZARD CAUSE SAFEGUARDS

Fire

Solvent Spray

Inhaling Toxic Substances

Explosion Hazard ­Incompatible Materials

General Safety

Cumulative Trauma
Disorders ("CTD's")

CTD's, or musculoskeletal
disorders, involve damage
to the hands, wrists,
elbows, shoulders, neck,
and back. Carpal tunnel
syndrome and tendonitis
(such as tennis elbow or
rotator cuff syndrome) are
examples of CTD's.

Solvent and coatings can be highly flammable or
combustible especially when sprayed.

During use and while cleaning and flushing,
solvents can be forcefully expelled from fluid
and air passages. Some solvents can cause eye
injury.

Certain materials may be harmful if inhaled, or if
there is contact with the skin.

Halogenated hydrocarbon solvents - for
example; methylene chloride and 1,1,1, ­Trichloroethane are not chemically compatible
with the aluminum that might be used in many
system components. The chemical reaction
caused by these solvents reacting with aluminum
can become violent and lead to an equipment
explosion.

Improper operation or maintenance of
equipment.

Use of hand tools may cause cumulative trauma
disorders ("CTD's").

CTD's, when using hand tools, tend to affect the
upper extremities. Factors which may increase
the risk of developing a CTD include:

1. High frequency of the activity.

2. Excessive force, such as gripping, pinching,
or pressing with the hands and fingers.

3. Extreme or awkward finger, wrist, or arm
positions.

4. Excessive duration of the activity.

5. Tool vibration.

6. Repeated pressure on a body part.

7. Working in cold temperatures.

CTD's can also be caused by such activities as
sewing, golf, tennis, and bowling, to name a few.

Adequate exhaust must be provided to keep air free of
accumulations of flammable vapors.

Smoking must never be allowed in the spray area.

Fire extinguishing equipment must be present in the spray
area.

Wear eye protection.

Follow the requirements of the Material Safety Data Sheet
supplied by your coating material manufacturer.

Adequate exhaust must be provided to keep the air free of
accumulations of toxic materials.

Use a mask or respirator whenever there is a chance of inhal­ing sprayed materials. The mask must be compatible with the
material being sprayed and its concentration. Equipment must
be as prescribed by an industrial hygienist or safety expert,
and be NIOSH approved.

Guns with stainless steel internal passageways may be used
with these solvents. However, aluminum is widely used in
other spray application equipment - such as material pumps,
regulators, valves, and this gun and cup. Check all equip­ment items before use and make sure they can also be used
safely with these solvents. Read the label or data sheet for
the material you intend to spray. If in doubt as to whether or
not a coating or cleaning material is compatible, contact your
material supplier.

Operators should be given adequate training in the safe use
and maintenance of the equipment (in accordance with the
requirements of NFPA-33, Chapter 15). Users must comply
with all local and national codes of practice and insurance
company requirements governing ventilation, fire precautions,
operation, maintenance, and housekeeping. These are OSHA
Sections 1910.94 and 1910.107 and NFPA-33.

Pain, tingling, or numbness in the shoulder, forearm, wrist,
hands, or fingers, especially during the night, may be
early symptoms of a CTD. Do not ignore them. Should you
experience any such symptoms, see a physician immediately.
Other early symptoms may include vague discomfort in the
hand, loss of manual dexterity, and nonspecific pain in the
arm. Ignoring early symptoms and continued repetitive use of
the arm, wrist, and hand can lead to serious disability. Risk is
reduced by avoiding or lessening factors 1-7.

NOTE

Information that you should pay special
attention to.
