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.

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 (19).

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

Ωis 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 distorted

spray patterns

5. Ensure the tip of the nozzle is clean and

free from damage. Build up of dried

paint can distort the spray pattern.

6. Lubrication – stud/screw (20,22), needle

(12) and air valve (15) should be oiled

each day.

Preventative Maintenance

Operation

1. Mix coating material to manuf acturers

instructions

2. Turn needle adjusting screw (14)

counter-clockwise until first thread

shows

3. Turn pattern valve (8) counter-clockwise

to fully open

4. Adjust inlet air pressure to give 1.6 bar

(23psi) 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 (14) 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 (8)

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.

Nozzle (3) and Needle (12) – Remove

parts in the following order: 14, 13, 12,

1, 2 and 3. Examine the seal (4) and

replace if damaged. Replace any other

worn or damaged parts and re-assemble

in reverse order. Recommended

tightening torque for nozzle (3) 20-27

Nm (15-20 lbf ft)

Packing – Remove parts 14, 13, 12.

Unscrew cartridge (26). Fit new cartridge

finger tight. Re-assemble parts 12, 13,

and 14 and tighten Packing Nut (25) with

spanner sufficient to seal but to allow

free movement of needle. Lubricate with

gun oil.

Air valve – Remove parts 17, 16 and

15. Clean or replace Valve. Re-

assemble parts in reverse order.

Spreader valve – Caution: always

ensure that the valve is in the fully open

position by turning screw fully counter-

clockwise before fitting to body.
