Technical Bulletin
TEKNA Gravity Feed Spraygun
IMPORTANT: Read and follow all instructions and Safety Precautions before using this equipment. Keep
for future use.
The TEKNA Gravity Feed Spraygun Kit complies to ATEX regulations 94/9/EC, protection level II 2 G X, Suitable for
use in Zones 1 and 2.
DeVilbiss Automotive Renishing reserves the right to modify equipment specication without prior notice.
Operational Description
The TEKNA spraygun is a lightweight professional gun designed to handle both water-based and solvent-based
coating materials. Both HVLP and high efciency models are available.
High volume, low pressure (HVLP) models are designed to reduce overspray and provide maximum transfer
efciency by limiting air cap pressure to 0.7 bar (10 psi) (complies with rules issued by SCAQMD and other air
quality authorities).
HVLP models will produce approximately 0.7 bar (10 psi) air cap pressure at 1.8 bar (26 psi) gun inlet pressure
with the trigger pulled. HVLP air cap #202 is designed for optimum basecoat applications. HVLP air cap #909
is designed for optimum clear coat applications. Two air cap test kits are available (see Accessories) which can
be utilized to set the exact air cap pressure.
High efciency models use air cap #7E7. These models are designed to provide optimum atomization of
virtually all waterborne or solvent-based common coating materials at increased application rates while
maintaining very high transfer efciency. High efciency models, when tested under recommended conditions
with automotive renishing materilas, have been found to exceed 65% transfer efciency.
High efciency models comply with SCAQMD rules and certain other air quality authorities. Refer to the website
www.autorefinishdevilbiss.com for a complete listing of approved areas and requirements for regulatory
compliance.
IMPORTANT: 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 specic material, contact your TEKNA Distributor or
TEKNA 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 bulletin contains information that is important for you to know and understand. This information relates to USER SAFETY and PRE-
VENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the following symbols. Please pay particular attention to
these sections.
NOTE
Important safety information – A hazard that may
cause serious injury or loss of life.
Important information that tells how to prevent damage
to equipment, or how to avoid a situation that may cause
minor injury.
Information that you should pay special attention to.
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 and coatings can be highly ammable or
combustible especially when sprayed.
Adequate exhaust must be provided to keep air free of accumulations of
ammable vapours.
Smoking must never be allowed in the spray area.
Fire extinguishing equipment must be present in the spray area.
Solvent Spray During use and while cleaning and ushing, solvents
can be forcefully expelled from uid and air passages.
Some solvents can cause eye injury.
Wear eye protection.
Inhaling Toxic Substances Certain materials may be harmful if inhaled, or if there
is contact with the skin.
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.
Explosion Hazard –
Incompatible Materials
Halogenated hydrocarbon solvents – for example;
methylene chloride and 1,1,1,-Trichloroethane are
not chemically compatible with the aluminium that
might be used in many system components. The
chemical reaction caused by these solvents reacting
with aluminium can become violent and lead to an
equipment explosion.
Guns with stainless steel internal passageways may be used with these solvents.
However, aluminium is widely used in other spray application equipment – such
as material pumps, regulators, valves, and cups. 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.
General Safety Improper operation or maintenance of equipment. 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, re precautions, operation,
maintenance, and housekeeping. These are OSHA Sections 1910.94 and
1910.107 and NFPA-33.
Cumulative Trauma disorders
(“CTD’s”)
CTD’s, or musculoskeletal
disorders, involve damage
to the hands, wrists, elbow,
shoulders, neck and back.
Carpal tunnel syndrome
and tendonitis (such as
tennis elbow or rotator
cuff syndrome) are examples
of CTD’s.
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 ngers.
3. Extreme or awkward nger, 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.
Pain, tingling, or numbness in the shoulder, forearm, wrist, hands, or ngers,
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 nonspecic 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.
