Operation Manual
FLG5 – Pressure-Feed Spray Gun
Important
Read and follow all instructions and Safety Precautions before using this
equipment
Description
The FLG5 pressure feed Spraygun is fitted with a 1.4mm Nozzle for use with common coating
materials. A 1.1mm Nozzle and Needle is available as an alternative. The FLG5 Spraygun 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 suppliers 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 sheets and follow any
recommendations 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 spraygun to earth should be checked with an
ohmeter. A resistance of less than 106Ohms is recommended.
2 Attach fluid supply hose to Fluid Inlet (28).
Operation
1. Mix coating material to manufacturers instructions
2. Turn needle adjusting screw (18) clockwise to prevent movement.
3. Turn spreader valve (10) counter-clockwise to fully open.
4. Adjust inlet air pressure (For recommended figures see Specifications) at the gun inlet with
the gun triggered. (pressure gauge attachment shown under Accessories is recommended
for this).
5. Turn needle adjusting screw counter clockwise until first thread shows.
6. Test spray. If the finish is too dry reduce airflow by reducing air inlet pressure or by the
Airflow Valve (22). Screw the Adjusting Knob in to reduce pressure.
7. If finish is too wet reduce fluid flow by turning needle screw (18) clockwise or reducing the
fluid pressure. If atomisation is too coarse, increase inlet air pressure. If too fine reduce inlet
pressure.
8. The pattern size can be reduced by turning adjusting valve (10) clockwise.
9. Hold gun perpendicular to surface being sprayed. Arcing or tilting may result in uneven
coating.
10.The recommended spray distance is 150-200 mm (6”-8”).
11.Spray edges first. Overlap each stroke a minimum of 50%. Move gun at a constant speed.
12.Always turn off air and fluid supply and relieve pressure when gun is not in use.
Preventative Maintenance
1. Turn off air and coating supply and relieve pressure in the supply lines, or if using QD
system, disconnect from airline and fluid line.
2. Remove air cap (1) & (2) and clean. If any of the holes in the cap are blocked with coating
material use a toothpick to clean. Never use metal wire which could damage the cap and
produce distorted spray patterns
3. Ensure the tip of the nozzle (3) is clean and free from damage. Build up of dried paint can
distort the spray pattern.
4. Lubrication – stud (24), needle (16) and air valve (13) should be oiled each day.
