FLG5 – Gravity Feed Spraygun
Important
Read and follow all instructions and Safety warnings before using this
equipment
Description
The FLG5 Gravity Spraygun is fitted with a 1.4 or 1.8mm Nozzle for topcoat
applications. Alternative 2.0mm Nozzle and Needles are available for primer use. The
FLG5 Gravity Feed Spraygun is approved to ATEX regulations 94/9/EC, protection
level; II 2 G X

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 spraygun 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 and safety data
sheets for the material before spraying
and follow any recommendations. 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
spraygun.
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 spraygun 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
sprayguns 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 use. 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
106Ωis recommended.
2. Air supply should be filtered and
regulated.
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 in 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 (see accessories) which
has the correct tools for this 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.
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
airflow 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.
