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.
PERSONAL PROTECTIVE EQUIPMENT
Toxic vapors – 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.
ITWIF reserve the right to modify equipment specification without prior notice.
B. Holt, General Manager
30th June 2003
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. 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 5/16" ID.
2. Attach fluid supply hose to Fluid
Inlet (15).
OPERATION
1. Mix coating material to manufacturers instructions
2. Turn needle adjusting screw (7)
clockwise to prevent movement.
3. Turn spreader valve (5) counterclockwise 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 or
full needle travel is achieved.
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 reducing the fluid pressure.
If atomization is too coarse, increase
inlet air pressure. If too fine reduce
inlet pressure.
8. The pattern size can be reduced by
turning spreader 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.
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), packing
(4) 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-assembl e i n reverse o rder.
Recommended tightening torque for
nozzle (2) 9.5-12 Nm (80-100 lbf in).
Packing – Remove parts 7, 8, 9. Unscrew
