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.

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 Spray
Solvent and coatings can be highly ammable or
combustible especially when sprayed.
During use and while cleaning and ushing, solvents
can be forcefully expelled from uid and air passages.
Some solvents can cause eye injury.
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.

Incompatible Materials
General Safety
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.
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 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.
Improper operation or maintenance of equipment. Operators should be given adequate training in the safe use and maintenance of
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.
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, 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.
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.
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.

INSTALLATION
For maximum transfer efciency, do not use more pressure than
is necessary to atomise the material being applied.
1. Connect the gun to a clean, moisture and oil free air
supply using a hose size of at least 8 mm (5/16") I.D. hose.
Do not use 6 mm I.D. hose (8 m x 6 mm hose at 510 LPM
has a pressure loss of 1.8 bar. 8 m x 8 mm hose at 510 LPM
has a pressure loss of 0.6 bar. [Do not use 1/4" I.D. hose
(25' x 1/4" hose at 18 CFM has a pressure loss of 25 psi.
25' x 5/16" hose at 18 CFM has a pressure loss of 8 psi).]
Depending on hose length, larger I.D. hose may be required.
NOTE
When gun is triggered on, adjust inlet air pressure
(for recommended pressures see Chart 1 under Parts
Replacement) at the gun inlet. (Pressure gauge shown under
Accessories is recommended for this). Do not use more
pressure than is necessary to atomise the material being
applied. Excess pressure will create additional overspray and
reduce transfer efciency.
NOTE
If quick connects are required, use only high ow quick con-
nects approved for HVLP use. Other types will not ow enough
air for proper gun operation.
NOTE
If an air adjusting valve is used at the gun inlet, use a DeVilbiss air
adjusting valve. Some competitive adjusting valves have signicant pressure drop that can adversely affect spray performance.
DeVilbiss air adjusting valves have minimal pressure drop.
2. Attach the gravity feed cup to the material inlet.
NOTE
Protective coating and rust inhibitors have been used
to keep the gun in good condition prior to shipment.
Before using the gun, ush it with solvents so that these
materials will be removed from uid passages.
OPERATION
1. Mix coating material to manufacturer’s instructions and strain
material.
2. Fill the cup with the required amount of material.
Fill to no more than 19 mm (3/4") from the top of the cup.
DO NOT OVERFILL.
3. Attach Cup Lid.
4. Turn uid adjusting knob (18) clockwise to prevent uid
needle movement.
5. Turn spreader valve adjusting knob (23) counter clockwise to
fully open.
6. Trigger gun on and adjust inlet air pressure (for
recommended gures see Chart 1 under Parts Replacement)
at the gun inlet. (Pressure gauge shown under Accessories is
recommended for this).
7 Turn uid adjusting knob counter clockwise until rst
thread shows.
8. Test spray. If the nish is too dry, reduce airow by reducing
air inlet pressure.
9. If nish is too wet, reduce uid ow by turning uid adjusting
knob (18) clockwise. If atomisation is too coarse, increase inlet
air pressure. If too ne, reduce inlet pressure.
10. The pattern size can be reduced by turning spreader valve
adjusting knob (23) clockwise.
11. Hold gun perpendicular to surface being sprayed. Arcing
or tilting may result in uneven coating.
12. The recommended spray distance is 150-200 mm (6"–8").
13. Spray edges rst. Overlap each stroke a minimum of 75%. Move
gun at a constant speed.
14. Always turn off air supply and relieve pressure when gun is not
in use.
PREVENTIVE MAINTENANCE & CLEANING
To clean air cap and uid nozzle, brush exterior with a stiff bristle
brush. If necessary to clean cap holes, use a broom straw or
toothpick if possible. If a wire or hard instrument is used, extreme
care must be used to prevent scratching or burring of the holes which
will cause a distorted spray pattern.
To clean uid passages, remove excess material from cup, then ush
with a suitable solvent. Wipe gun exterior with a solvent dampened
cloth. Never completely immerse in solvent as this is detrimental to
the lubricants and packings.
NOTE
When replacing the uid nozzle or uid needle, replace both
at the same time. Using worn parts can cause uid leakage.
See page 11, Chart 2. Also, replace the needle packing at this
time. Lightly lubricate the threads of the uid nozzle before
reassembling. Torque to 18–20 nm (13–15 ft-lbs). Do not over
tighten the uid nozzle.
CAUTION
To prevent damage to uid nozzle (8) or uid needle (15), be
sure to either 1) pull the trigger and hold while tightening or
loosening the uid nozzle, or 2) remove uid adjusting knob (18)
to relieve spring pressure against needle collar.
SPRAY GUN LUBRICATION
Daily, apply a drop of spray gun lubricant at trigger stud (39) and the
stem of air valve (32) where it enters air valve assembly. The shank
of uid needle (15) where it enters packing nut (28) should also be
oiled. Fluid needle packing (26) should be lubricated periodically.
Make sure air separator (9) and air cap retaining ring (1) threads are
clean and free of foreign matter. Before assembling air cap retaining
ring to air separator, clean the threads thoroughly, then add two
drops of spray gun lubricant to threads. Fluid needle spring (16) and
air valve spring (33) should be coated with a
very light grease, making sure that
any excess grease will not clog the
air passages.

Remedies for the top-heavy, bottom-heavy, right-heavy, and left-heavy patterns:
1. Determine if the obstruction is on the air cap or the uid nozzle. Do this by making a test spray pattern. Then,
rotate the cap one-half turn and spray another pattern. If the defect is inverted, obstruction is on the air cap.
Clean the air cap as previously instructed. Also check for dried paint just inside the cap center hole opening;
remove by washing with solvent.
2. If the defect is not inverted, it is on the uid nozzle. Clean nozzle. Check for a ne burr on the edge of the uid
nozzle. Remove with #600 wet or dry sandpaper.
