SAFETY WARNINGS

EE

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 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.

suitable for use with

.

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 nonoriginal 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.

EE

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

Installation

ohmeter. A resistance of less than 10 Ohms is recommended.

2. Attach the Cup Lid assembly (27) to the Fluid Inlet connector (15).

3. Position the Yoke at right angles to the Gun with the Cam lever (21) to the front (see picture). Make sure the vent hole in the lid is positioned under the Yoke and the hole in the diaphragm (25) is 180° to the Lid vent hole.

Operation

6

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 to the Lid assembly.

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

5. Turn spreader valve (5) counterclockwise 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).

Preventative Maintenance

1. Turn off air and relieve pressure in

the supply lines, or if using QD system, disconnect from airline.

2. Release Cup and raise the tube out

of the material. Trigger the Gun and allow material to drain back into the cup. Dispose of the surplus material.

3. Clean the cup. Remove the Drip free

diaphragm and clean. Replace the diaphragm if is split or damaged.

4. Check the breather hole in the Lid is

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

9. If finish is too wet reduce fluid flow by turning needle screw (7) clockwise or reducing the fluid pressure. 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.

not blocked.

5. 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

6. Ensure the tip of the nozzle (2) is

clean and free from damage. Build up of dried paint can distort the spray pattern.

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

Replacement of Parts

EE

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 counterclockwise before fitting to body.
