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 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 Attach fluid supply hose to Fluid

Inlet (15).

1. Turn off air and coating supply and

relieve pressure in the supply lines,

or if using QD system, disconnect

from airline and fluid line.

2. 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

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

clean and free from damage. Build

up of dried paint can distort the

spray pattern.

4. Lubrication – stud/screw (6), needle

(9) and air valve (11) should be

oiled each day.

Preventative Maintenance

Operation

1. Mix coating material to

manufacturers instructions

2. Turn needle adjusting screw (7)

clockwise to prevent movement.

3. Turn spreader valve (5) counter-

clockwise to fully open.

4. Adjust inlet air pressure (For

recommended figures see

Specifications) at the gun inlet with

the gun triggered. (pressure gauge

attachment shown under

Accessories is recommended for

this).

5. Turn needle adjusting screw counter

clockwise until first thread shows.

6. 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.

7. 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.

8. The pattern size can be reduced by

turning adjusting valve (5) clockwise.

9. Hold gun perpendicular to surface

being sprayed. Arcing or tilting may

result in uneven coating.

10. The recommended spray distance is

150-200 mm (6”-8”).

11. Spray edges first. Overlap each

stroke a minimum of 50%. Move gun

at a constant speed.

12. Always turn off air and fluid supply

and relieve pressure when gun is not

in use.

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.
