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
Halogenated Hydrocarbons
Static Electricity can be
generated by fluid and/or air
passing through hoses, by the
spraying process and by cleaning nonconductive 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 nonoriginal 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.
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 (13).
Recommended hose size 8 mm
Operation
1. Mix coating material to manufacturers
instructions
2. Turn needle adjusting screw (7)
clockwise to prevent movement.
3. Turn spreader valve (5) counter-
clockwise to fully open.
4. Adjust inlet air pressure to give 3 bar
(44 psi) 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 (14).
Screw the Adjusting Knob (14) in to
reduce pressure.
7. If finish is too wet reduce fluid flow by
turning needle screw (7) clockwise or
bore. The hose must be conductive
and electrical bond from the
spraygun to earth should be checked
with an ohmeter. A resistance of less

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 (5) 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.
Ohms is recommended.
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) 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 (2) is
clean and free from damage. Build
up of dried paint can distort the spray
pattern.
4. Lubrication – stud/screw (6), needle
(9) and air valve (11) should be oiled
each day.

Replacement of Parts
Nozzle (2) and Needle (9) – Remove
parts in the following order: 7, 8, 9, 1 and
2. Replace any worn or damaged parts
and re-assemble in reverse order.
Recommended tightening torque for
nozzle (2) 9.5-12 Nm (80-100 lbf in).
Packing – Remove parts 7, 8, 9.
Unscrew cartridge (4). Fit new cartridge
finger tight. Re-assemble parts 9, 8, and
7 and tighten cartridge (4) with spanner
sufficient to seal but to allow free
movement of needle. Lubricate with gun
oil.
