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.

Specification

Air supply connection - Universal 1/4 BSP and NPS

Maximum static inlet pressure - P1= 9 bar (130 psi)

Nominal gun inlet pressure with gun triggered - 2 bar (29 psi)

Gun Weight - 765g

Materials of Construction

Gun body - Anodised Aluminium

Nozzle - Stainless steel

Needle - Stainless Steel

Cup - Acetal and Stainless Steel

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.

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

Preventative Maintenance

Nozzle (2) and Needle (7) – Remove

parts in the following order: 10, 8, 7, 1

and 2. Replace any worn or damaged

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

10 and tighten cartridge (4) with spanner

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.
