equipment

Description

The Compact Gravity feed Spraygun Kit complies to ATEX regulations 94/9/EC, protection

level; II 2 G X, Suitable for use in Zones 1 and 2

Important: : These Sprayguns are suitable for use with both waterbased and solvent based

coating materials. The design uses EPA compliant (Devilbiss Trans-Tech®) and HVLP

atomising technology to reduce overspray and improve coating efficiency. These guns are not

designed for use with highly corrosive and/or abrasive materials and if used with such materials

it must be expected that the need for cleaning and/or replacement of parts will be increased. If

there is any doubt regarding the suitability of a specific material contact your local Distributor or

ITW Finishing direct.

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.

Specification

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.

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

Preventative Maintenance

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 (For

recommended figures see

Specifications) 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.

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.
