SAFETY WARNINGS

Fire and explosion

Solvents and coating materials can be highly flammable or combustible when sprayed.

ALWAYS refer to the coating material supplier’s 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 spray gun 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

are otherwise harmful to health. Always read all labels, safety data sheets and follow any

recommendations for the material before spraying. 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 spray gun.

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 spray gun 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 spray guns 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 used. Flush the equipment through with

appropriate solvent before use.

Fix the spray gun using mounting stem ref.28 and secure it with nut ref.29.

SETTING

1. The « ATOM » air valve control the atomizing air pressure

« FAN » reduces the spray pattern size. To increase the

pressure turn clockwise & reverse to reduce turn counter-

clockwise.

2. Fluid flow can be adjusted with the rear ratchet knob; fluid

flow is increased when you turn the knob counter-

clockwise.

STARTING-UP

1. Turn the needle adjusting knob (25) clockwise until the needle is fully closed.

2. Turn the “Fan” and “Atom air valves counter-clockwise to be full open.

3. Set the air pressure at the air regulator to achieve recommended pressures above.

4. Turn the adjusting knob counter clockwise to obtain the desired fluid flow.

5. Test spray. If the finish is too dry or fine, reduce airflow by reducing air inlet pressure or by the valve

(13 Atom) screwing it in clockwise, or increase fluid flow using ratchet knob rotating counter clockwise.

6. If the finish is too wet, turn the needle adjusting knob (25) in clockwise to reduce the fluid flow, or

reduce the fluid pressure. If the atomization is too coarse, increase inlet air pressure, or reduce fluid

flow.

7. The pattern size can be reduced by turning adjusting valve “Fan” (13) clockwise.

8. The spray pattern will give the best results when perpendicular to the target.

9. The recommended spray distance is 150-220 mm (6’’ to 8’’).

10. Spray edges first. Overlap each stroke a minimum of 50%. Move gun at a constant speed.

11. Always turn off air and fluid supply and relieve pressure and clean down when gun is not in us.

PREVENTIVE MAINTENANCE

Turn off air and coating supply and relieve pressure in the supply lines, before any maintenance

operation.

Tip (5) & needle (18)

Remove the air cap and its retaining ring by unscrewing by

¼ turn counter- clockwise (Fig 1).

Remove the tip and its baffle (5) by unscrewing by ¼ turn counter- clockwise (Fig 2). Unscrew the

adjusting needle knob fully in counter-clockwise rotation and pull out the needle at the back.

Make sure the vent hole is clear.

The fluid tip and baffle are permanently fitted together. There is no

possibility to separate them. The baffle will be damaged if you try to

dismantle.

FIG 1 FIG 2

PACKING

Unscrew the 4 screws to disassemble the gun head. Remove the packing bellows seal. Clean or

replace if the packing is damaged.

FAN & ATOM AIR VALVE (13)

Before assembling, check the air valve is in fully open position by

unscrewing it counter-clockwise.

Piston (15), o ring (16) & (14)

Unscrew the rear housing (19) at the back of the gun body counter

clockwise, pull out the needle (18).

Use bent nose pliers so to pull out the piston which has a 12mm

internal groove for this purpose.

It’s recommended to replace the o ring (14) into the gun body as soon

you disassemble the Piston.

When replacing the piston, slightly lubricate all the O rings before

fitting into the gun body.

PREVENTIVE MAINTENANCE

1. Turn off air and coating supply and relieve pressure in the supply lines, or disconnect from airline and

fluid line.

2. Remove air cap and clean (3). 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 fluid tip (5) of the nozzle is clean and free from damage especially the outside at the front

diameter. Any build up of dried paint can distort the spray pattern.
