FLG5 – Gravity-feed Spray Gun

Important

Read and follow all instructions and Safety Precautions before using this

equipment

Description

The FLG5 gravity spray gun is fitted with a 1.4 mm nozzle for topcoat applications. Alternative

2.0mm nozzle and needles are available for primer use. The FLG5 gravity-feed spray gun is

approved to ATEX regulations 94/9/EC, protection level;

II 2 G X. Suitable for use in Zones 1 and 2

Important: These spray guns are suitable for use with both water-based and solvent-based

coating materials. The design uses EPA compliant atomising (Devilbiss Trans-Tech®)

technology to reduce overspray and improve coating efficiency. Nozzles and needles are

manufactured in stainless steel. 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 local Distributor or ITW Finishing direct.

SAFETY WARNINGS

Fire and explosion

Solvents and coating materials can be highly flammable or combustible when sprayed.

ALWAYS refer to the coating material supplier’s instructions and COSHH sheets

before using this equipment.

Users must comply with all local and national codes of practice and insurance company

requirements governing ventilation, fire precautions, operation and house-keeping of

working areas.

This equipment, as supplied, is NOT suitable for use with Halogenated

Hydrocarbons.

Static electricity can be generated by fluid and/or air passing through hoses, by the

spraying process and by cleaning non-conductive parts with cloths. To prevent ignition

sources from static discharges, earth continuity must be maintained to the spray gun

and other metallic equipment used. It is essential to use conductive air and/or fluid

hoses.

Personal Protective Equipment

Toxic vapours – When sprayed, certain materials may be poisonous, create irritation or

be otherwise harmful to health. Always read all labels, safety data and follow any

recommendations sheets for the material before spraying. If in doubt, contact your

material supplier.

The use of respiratory protective equipment is recommended at all times. The type of

equipment must be compatible with the material being sprayed.

Always wear eye protection when spraying or cleaning the spray gun.

Gloves must be worn when spraying or cleaning the equipment.

Training – Personnel should be given adequate training in the safe use of spraying equipment.

Misuse

Never aim a spray gun at any part of the body.

Never exceed the max. recommended safe working pressure for the equipment.

The fitting of non-recommended or non-original spares may create hazards.

Before cleaning or maintenance, all pressure must be isolated and relieved from the equipment.

The product should be cleaned using a gun-washing machine. However, this equipment should

not be left inside gun-washing machines for prolonged periods of time.

Noise Levels

The A-weighted sound level of spray guns may exceed 85 dB (A) depending on the set-

up being used. Details of actual noise levels are available on request. It is

recommended that ear protection is worn at all times when spraying.

Operating

Spray equipment using high pressures may be subject to recoil forces. Under certain

circumstances, such forces could result in repetitive strain injury to the operator.

Installation

Important: To ensure that this equipment reaches you in first class condition, protective coatings

have been used. Flush the equipment through with a suitable solvent before use.

1. Attach air hose to connector (19). Recommended hose size 8 mm bore. The hose must be

conductive and electrical bond from the spray gun to earth should be checked with an

ohmmeter. A resistance of less than 106Ωis recommended.

2. Air supply should be filtered and regulated.

Operation

1. Mix coating material to manufacturers instructions.

2. Turn needle adjusting screw (18) counter-clockwise until first thread shows.

3. Turn pattern valve (10) counter-clockwise to fully open.

4. Adjust inlet air pressure to give 2.4 bar (35 psi) at the gun inlet with the gun triggered. (pressure

gauge attachment shown under Accessories is recommended for this).

5. Test spray. If the finish is too dry, reduce air flow by reducing inlet pressure. If finish is too wet,

reduce fluid flow by turning needle screw (18) clockwise. If atomisation is too coarse, increase

inlet air pressure. If too fine, reduce inlet pressure.

6. The pattern size can be reduced by adjusting valve (10).

7. Hold gun perpendicular to surface being sprayed. Arcing or tilting may result in uneven coating.

8. The recommended spray distance is 150-200 mm (6”-8”).

9. Spray edges first. Overlap each stroke a minimum of 50%. Move gun at a constant speed.

10.Always turn off air supply and relieve pressure when gun is not in use.

Preventative Maintenance

1. Turn off air supply and relieve pressure in the airline or, if using QD system, disconnect from

airline.

2. Empty coating material into a suitable container and clean the gun and cup, preferably in a gun

wash machine.

3. IMPORTANT– the cup must not be cleaned or rubbed with a dry cloth or paper. It is

possible to generate a static charge by rubbing which, if discharged to an earthed object,

could create an incendive spark and cause solvent vapours to ignite. Only use a

dampened cloth or antistatic wipes if additional cleaning is required within a hazardous

area.

4. Remove air cap (2) and clean. If any of the holes in the cap are blocked with coating material,

only use the cleaning kit KK-4584 which has the correct tools for this (see Accessories) or, a

toothpick to clean. Using any other tool could damage the cap and produce distorted spray

patterns.

5. Ensure the tip of the nozzle is clean and free from damage. Build-up of dried paint can distort the

spray pattern.

6. Lubrication – Trigger stud (24), needle (16) and air-valve spindle (13) should be oiled each day.

Replacement of Parts

Nozzle (3) and needle (16) – Remove parts in the following order: 18, 17, 16, 1, 2 and 3. Check

condition of nozzle seal (4) and replace if necessary. Replace any worn or damaged parts and

re-assemble in reverse order. Recommended tightening torque for nozzle (3) 16-20 Nm (150-

180 lbf in).

Packing – Remove parts 18, 17, 16. Unscrew packing nut (7). Remove packing (6). Fit new

packing (6) and nut (7). Re-assemble parts 16, 17, and 18 and tighten packing nut (7) with

spanner sufficient to seal but to allow free movement of needle. Lubricate with gun oil.

Air-valve Seal Kit K-5040

1. Remove adjusting knob (18), spring (17), and needle (16).

2. Loosen housing (15).

3. Remove housing (15) and air-valve spring (14).

4. Remove spindle (13).

5. Using service tool (32), engage groove behind the valve seat (12) and remove valve seat.

6. Push out the front air-valve seal (11).

7. Turn the gun upside down and let the seal fall out.

8. Fit new front seal (11) to service tool.

9. Fit new seal to gun body and press firmly to ensure seal is engaged.

10. Fit new valve seat (12) to service tool and fit valve seat into gun body.

11. Remove rear sir-valve seal (11) from housing (15) with a hooked instrument.

12. Fit new seal to service tool and fit deal to housing (15).

13. Replace spindle (13).

14. Replace valve spring (14), screw in housing (15) and tighten.

15. Screw reverse end of service tool into housing until fully engaged. Tighten by hand to seat

the valve seat. Remove tool.

16. Fit needle (16), spring (17) and knob (18).

17. Adjust needle packing (7) with spanner sufficient to seal but to allow free movement of

needle. Lubricate with gun oil.

Spreader valve (10) – Caution: always ensure that the valve is in the fully open position by

turning screw fully counter-clockwise before fitting to body.
