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 Refinishing reserves the right to modify equipment specification 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 efficiency models are available.
High volume, low pressure (HVLP) models are designed to reduce overspray and provide maximum transfer

efficiency 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 efficiency 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 efficiency. High efficiency models, when tested under recommended conditions

with automotive refinishing materilas, have been found to exceed 65% transfer efficiency.
High efficiency 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 specific 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 flammable or

combustible especially when sprayed.

Adequate exhaust must be provided to keep air free of accumulations of

flammable 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 flushing, solvents

can be forcefully expelled from fluid 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, fire 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 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.

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.

TB-1016-A

INSTALLATION

For maximum transfer efficiency,

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 efficiency.

NOTE

If quick connects are required, use only high flow quick con-

nects approved for HVLP use. Other types will not flow 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 signifi-

cant 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, flush it with solvents so that these

materials will be removed from fluid 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 fluid adjusting knob (18) clockwise to prevent fluid

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 figures see Chart 1 under Parts Replacement)

at the gun inlet. (Pressure gauge shown under Accessories is

recommended for this).

7 Turn fluid adjusting knob counter clockwise until first

thread shows.

8. Test spray. If the finish is too dry, reduce airflow by reducing

air inlet pressure.

9. If finish is too wet, reduce fluid flow by turning fluid adjusting

knob (18) clockwise. If atomisation is too coarse, increase inlet

air pressure. If too fine, 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 first. 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 fluid 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 fluid passages, remove excess material from cup, then flush

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 fluid nozzle or fluid needle, replace both

at the same time. Using worn parts can cause fluid leakage.

See page 11, Chart 2. Also, replace the needle packing at this

time. Lightly lubricate the threads of the fluid nozzle before

reassembling. Torque to 18–20 nm (13–15 ft-lbs). Do not over

tighten the fluid nozzle.

CAUTION

To prevent damage to fluid nozzle (8) or fluid needle (15), be

sure to either 1) pull the trigger and hold while tightening or

loosening the fluid nozzle, or 2) remove fluid 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 fluid 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 fluid 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 fluid nozzle. Clean nozzle. Check for a fine burr on the edge of the fluid

nozzle. Remove with #600 wet or dry sandpaper.
