SAFETY WARNINGS
EE
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
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.
suitable for use with
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.

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 (13).
Recommended hose size 8 mm bore.
The hose must be conductive and
electrical bond from the spraygun to
Operation
1. Mix coating material to manufacturers
instructions.
2. Fill the cup with the required amount
of material. Fill to no more than 25mm
(1“) from the top of the cup. DO NOT
OVERFILL.
3. Attach Cup Lid.
4. Turn needle adjusting screw (7)
clockwise to prevent movement.
5. Turn spreader valve (5) counterclockwise to fully open.
6. 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).
7. Turn needle adjusting screw counter
clockwise until first thread shows.
8. Test spray. If the finish is too dry
reduce airflow by reducing air inlet
earth should be checked with an
ohmeter. A resistance of less than
6
Ohms is recommended.

2. Air supply should be filtered and
regulated.
3. Attach Cup assembly (22) by
screwing into the Fluid Inlet of the
spraygun. Tighen when fully home.
pressure or by the Airflow Valve (14).
Screw the Adjusting Knob (14) in to
reduce pressure.
9. If finish is too wet reduce fluid flow by
turning needle screw (7) 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 adjusting valve (5) 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 50%. Move gun at a
constant speed.
14. Always turn off air supply and relieve
pressure when gun is not in use.
Preventative Maintenance
1. Turn off air and relieve pressure in
the supply lines, or if using QD
system, disconnect from airline.
2. Remove Cup Lid (20 )and empty
coating material into a suitable
container. Clean the gun and cup,
preferably in a gun wash machine.
Clean the cup.
3. Check the breather hole in the Lid

and the Drip Check Lid is not
blocked.
4. 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
5. Ensure the tip of the nozzle (2) is
