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 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

be 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 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 106Ohms is recommended.

2. Air supply should be filtered and regulated.

3. Attach Cup assembly (22) by screwing into the Fluid Inlet of the spraygun. Tighen when fully

home.

Operation

1. Mix coating material to manufacturers instructions.

2. Fill the cup with the required amount of material. Fill to no more than 25mm (1“) from the top of

the cup. DO NOT OVERFILL.

3. Attach Cup Lid.

4. Turn needle adjusting screw (7) clockwise to prevent movement.

5. Turn spreader valve (5) counter-clockwise to fully open.

6. Adjust inlet air pressure to give 3 bar (44 psi) at the gun inlet with the gun triggered. (pressure

gauge attachment shown under Accessories is recommended for this).

7. Turn needle adjusting screw counter clockwise until first thread shows.

8. Test spray. If the finish is too dry reduce airflow by reducing air inlet pressure or by the Airflow

Valve (14). Screw the Adjusting Knob (14) in to reduce pressure.

9. If finish is too wet reduce fluid flow by turning needle screw (7) clockwise. If atomisation is too

coarse, increase inlet air pressure. If too fine reduce inlet pressure.

10. The pattern size can be reduced by turning adjusting valve (5) clockwise.

11. Hold gun perpendicular to surface being sprayed. Arcing or tilting may result in uneven coating.

12. The recommended spray distance is 150-200 mm (6”-8”).

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

14. Always turn off air supply and relieve pressure when gun is not in use.

Preventative Maintenance

1. Turn off air and relieve pressure in the supply lines, or if using QD system, disconnect from

airline.

2. Remove Cup Lid (20 )and empty coating material into a suitable container. Clean the gun and

cup, preferably in a gun wash machine. Clean the cup.

3. Check the breather hole in the Lid and the Drip Check Lid is not blocked.

4. Remove air cap (1) 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 (2) is clean and free from damage. Build up of dried paint can distort

the spray pattern.

6. Lubrication – stud/screw (6), needle (9) and air valve (11) should be oiled each day.

Replacement of Parts

Nozzle (2) and Needle (9) – Remove parts in the following order: 7, 8, 9, 1 and 2. Replace any worn or

damaged parts and re-assemble in reverse order. Recommended tightening torque for nozzle (2) 9.5-12

Nm (80-100 lbf in).

Packing – Remove parts 7, 8, 9. Unscrew cartridge (4). Fit new cartridge finger tight. Re-assemble

parts 9, 8, and 7 and tighten cartridge (4) with spanner sufficient to seal but to allow free movement of

needle. Lubricate with gun oil.

Air Valve Seal Kit (16) - (Refer to photos 1 to 28 and fig 2)

1. Remove Adjusting Knob (7), Spring (8), and Needle (9).

2. Loosen Housing (10).

3. Remove Housing (10) and Airvalve Spring.

4. Remove Valve (11).

5. Using Service Tool SPN-7, engage groove behind the Valve Seat.

6. Remove Valve Seat.

7. Push out the Front Airvalve Seal with a finger.

8. Turn the Gun upside down and let the Seal fall out.

9. Fit New Front Seal to Service Tool.

10. Fit new Seal to gunbody and press firmly to ensure Seal is engaged.

11. Fit New Valve Seat to Service Tool. Groove must face outwards.

12. Fit Valve Seat to Gunbody.

13. Remove Rear Airvalve Seal from housing (10) with a hooked instrument.

14. Fit new Seal to Service Tool.

15. Fit Seal to Housing (10).

16. Replace Valve (11).

17. Replace Valve Spring and screw in Housing (10).

18. Tighten Housing.

19. Fit Needle (9).

20. Fit Spring (8) and Knob (7).

21. Adjust Needle Packing (4) with Spanner sufficient to seal but to allow free movement of needle.

Lubricate with gun oil.

Spreader valve (5) – Caution: always ensure that the valve is in the fully open position by turning screw

fully counter-clockwise before fitting to body.
