Operation Manual
PRi – Gravity Primer Spraygun
Important
Read and follow all instructions and Safety Precautions before using
this equipment
Description
The PRi Gravity Feed Spraygun Kit is approved to ATEX regulations 94/9/EC, protection level;
II 2 G X, Suitable for use in Zones 1, and 2
Important: These Sprayguns are suitable for use with both waterbased and solvent based
coating materials. The design uses EPA compliant atomising (Devilbiss Trans-Tech®)
technology to reduce overspray and improve coating efficiency. Nozzles and Needles are
manufactured in Stainless Steel. These guns are not designed for use with highly corrosive and/
or abrasive materials and if used with such materials it must be expected that the need for
cleaning and/or replacement of parts will be increased. If there is any doubt regarding the
suitability of a specific material contact your local Distributor or ITW Finishing direct.

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.

Operation
1. Mix coating material to manufacturers
instructions
2. Turn needle adjusting screw (10)
counter-clockwise until first thread
shows
3. Turn pattern valve (5) counter-
clockwise to fully open
4. Adjust inlet air pressure to give 2 bar
(29psi) 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 (10)
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 (5)
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.
Air Flow Valve (15)
1. If the airflow valve (15) is fitted this
can be used to reduce the inlet
pressure through the gun. Screw the
Adjusting Knob in to reduce pressure.
E
E 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 (13).
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.
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 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

parts and re-assemble in reverse order.
Recommended tightening torque for
nozzle (2) 17-20 Nm (150-180 lbf in)
Packing – Remove parts 10, 8, 7.
Unscrew cartridge (4). Fit new cartridge
finger tight. Re-assemble parts 7, 8, and

sufficient to seal but to allow free
movement of needle. Lubricate with gun
oil.
Air valve – Remove parts 6 and 12.
Unscrew valve assembly. Re-assemble
fitting spring to valve head
Spreader valve – Caution: always
ensure that the valve is in the fully open
position by turning screw fully counter-
clockwise before fitting to body.
