out of the paint nozzle. The spraying medium flows then unpressurized out of the paint nozzle due to
gravity and is simultaneously atomized by the compressed air that flows from the air nozzle.
1. Fill the gravity feed cup with the material. Do not overfill. Ensure that the vent hole in the cup lid
is clear.
2. Adjust the atomizing air pressure to 2-4 kgs / sq.cm. (28-56 psi).
3. It requires air about (8-10 cfm) 225-283 litre per minute depending on the liquid to be spray.
4. Close the fluid needle adjusting screw by turning clockwise.
5. Turn on the air at the source of supply and spray test area by turning the fluid needle adjusting
screw counter-clockwise until a full coat is obtained.
Maximum coating material temperature 50 deg C.
If the finish is too sandy and dry, reduce the viscosity of the coating material supply by turning the
adjusting screw counter-clockwise.
Increasing or decreasing the atomizing air pressure can also correct both the above. The most
efficient atomizing air pressure is the lowest possible air pressure that will give the desired effect.
The gun should be held perpendicular to the spray surface at all times. Do not arc the gun
as this produces and uneven coat of paint. The recommended spraying distance is 230mm (9”).
PREVENTIVE MAINTENANCE
Cleaning
1. Turn off air supply and release pressure.
2. Empty surplus coating material from cup and clean.
3. Remove air cap and clean by immersing in solvent, brush or wipe clean. If any holes in the
air cap are blocked use a toothpick or broom straw to remove the obstruction. Never use a
steel wire or hard implement which will damage the air cap and result in a distorted pattern.
Lubrication
Lubricate all moving parts daily with a few drops of light oil and occasionally place a light coating of
Vaseline on the needle spring. The packing may need to be oiled occasionally to keep them pliable.
Adjustment of fan width
To adjust fan width use spreader control. Spray pattern can be altered from flat to round
.
Reduction of material flow
Needle stroke and therefore material flow is infinitely reducible by turning the material flow
control screw.
Exchanging the nozzle set
When changing to another nozzle size, make sure that the complete nozzle set is exchanged.
Fix paint nozzle before paint needle.
After Use
Immediate cleanup with the appropriate cleaning solution must be done after use.
REPLACEMENT OF PARTS
Needle
1. Remove needle adjusting screw, spring for needle and needle. Replace any worn or damaged
parts ensuring that the fluid needle seats correctly in the fluid tip so that the movement of the
needle is not restricted.
Needle Packing
1. Remove needle as 1 above.
2. Remove nozzle and needle
3. Remove needle packing set. Replace any worn or damaged parts.
Re-assemble, reversing steps 1 to 3. Adjust packing so that the movement of the needle is
not restricted.
Air Valve Head
Remove threaded pin and air control knob. Replace any worn or damaged parts and re-assemble.
PERSONAL PROTECTIVE EQUIPMENT
Toxic vapours
- Certain materials when sprayed may be poisonous, create irritation or otherwise
be harmful to health. Always carefully read all labels and safety / performance data about the
material being sprayed and follow the necessary recommendations.
If in doubt, consult the material supplier
The use of respiratory protective equipment is recommended at all times while spraying. The type of
respiratory protective equipment used must be compatible with the material being sprayed and the
level of concentration.
Always wear eye protection while spraying or cleaning the equipment.
Gloves must be worn while spraying or cleaning the equipment with certain coating materials and
solvents.
TRAINING
Personnel should be given adequate training in the safe use and maintenance of this equipment.
Training courses on all aspects of the equipment are available. For details contact your local
representative. The instructions and safety precautions contained in this literature and the literature
supplied with the coating material should be understood before using the equipment.
Misuse
All spray guns project particles at high velocity and must never be aimed at body parts.
Never exceed the recommended safe working pressure for any of the equipment used.
The fitting of non-recommended or non-original accessories or spare parts may create hazardous
conditions.
Before dismantling the equipment for cleaning or maintenance, pressure, air and materials must be
isolated and released.
The disposal of non-metallic materials must be carried out in an appropriate manner. Burning may
generate toxic fumes. The removal of waste solvents and coating materials should be carried out by an
authorized local waste disposal service.
The materials used in the construction of this equipment are (bearing in mind the warning on
Halogenated Hydrocarbons) solvent resistant enabling the equipment to be cleaned using gun
washing machines. However, this equipment must not be left inside the gun washing machine for
prolonged periods of time after the automatic cleaning cycle has been completed. The solvents used
in the gun washing machine should be regularly checked to ensure that the equipment is not flushed
through with contaminated material. Follow the recommendations of the machine manufacturer.
Noise levels
IMPORTANT
: To ensure that this equipment reaches you in perfect condition, protective coatings, rust
inhibitors, etc. have been used. Flush all equipment through with a suitable solvent before use to
remove these agents present in the material passages.
Recommended air hose sizes
Attach air hose connector from a filtered regulated air supply.
OPERATION
The continuous A-weighted sound pressure level of this spray gun may exceed 85 dB (A) depending
on the air cap/nozzle set-up being used. Sound levels are measured using an impulse sound level
meter and analyzer, when the gun is being used in a normal spraying application. Details of actual
noise levels produced by the various air cap/nozzle set-ups are available on request.
Attach the air supply line to the air inlet (27). An air transformer installed as close as possible to the gun
will provide filtered and regulated air.
Recommended air supply hose size upto 10 meters long, (1/4”) bore.
Attach the gravity feed cup to the material inlet and ensure that the sealing washer is compressed.
The PILOT spray gun is designed for spraying paint and lacquers as well as other media with a
spraying viscosity of up to 70sec. in a DIN4 mm cup. The compressed air supply required for the
spraying is fed to the air connection that is screwed into the gun grip. Squeezing the trigger as far as the
first pressure point opens the air valve. When the trigger is squeezed further the paint needle is pulled
INSTALLATION
HP 59(High Performance) spray guns are easier to use than most spray guns. These lightweight
gravity feed spray guns are suitable for production work on articles of medium or large sizes. They
are ideal for spray-painting motorcar bodies, refrigerators, machinery, etc. Perfect balance,
comfortable handle and trigger action makes them easy and non-tiring to operate. A knob on the left
can easily control round to fan spray of pattern.
These gravity feed spray guns are supplied with a 0.6 lit. gravity cup.

Dear
Important:
These guns are not designed to be used with highly corrosive or highly abrasive
coating materials. Violation may increase the need for thorough cleaning and /or the necessity for
replacement of parts. If there is any doubt regarding the suitability of a specific material you may
seek advise and /or submit a sample for test.
Fire and Explosion
Solvents and coating materials can be highly flammable or combustible, especially when sprayed.
Workstations must be provided with adequate ventilation/exhaust to prevent the build-up of
flammable vapours.
Smoking and naked flames must not be allowed in the spraying or mixing areas.
Fire extinguishing equipment must be provided in the spraying and mixing areas.
Users must comply with all local and national codes of practice and insurance company
requirements governing ventilation, fire precautions, operation, maintenance and housekeeping
of workstations.
HALOGENATED HYDROCARBON SOLVENTS
for example 1,1,1 Trichloroethane & Methylene
Chloride can chemically react with aluminium and galvanized or zinc coated parts and cause an
explosion hazard. Read the label and data sheet of the material you intend to spray.
DO NOT USE SOLVENTS OR COATING MATERIALS CONTAINING HALOGENATED
HYDROCARBONS WITH THIS EQUIPMENT.
Static electricity
is generated by fluid moving through pipes and hoses. A static spark, capable of
igniting certain solvents and coating materials could be produced by high fluid flow rates. To prevent
the risk of fire or explosion, earth continuity to the spray equipment and object being sprayed should
be maintained.
