INSTALLATION

SETTING

1. The ATOM ‘A’ air valve controls the atomizing air

pressure FAN ‘F’ valve reduces the spray pattern

size. To increase the pressure turn clockwise, 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.

3. For the arrangement of the parts, refer to the

exploded view on page 5.

STARTING UP

1. Turn the needle adjusting knob (25) clockwise

until the needle is fully closed.

2. Turn the FAN ‘F’ and ATOM ‘A’ air valves (13)

counter-clockwise to be full open.

3. Use the air cap chart above to set the air pressure

at the air regulator to achieve recommended

pressures above.

4. Turn the adjusting knob (25) counter clockwise to

obtain the desired fluid flow.

5. Test spray. If the finish is too dry or fine, reduce

the airflow by reducing the air inlet pressure or

by screwing the valve ATOM ‘A’ (13) in clockwise,

or increase the fluid flow using ratchet knob,

rotating counter clockwise.

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. Mount the spray gun using mounting stem ref.28 and secure it

with nut ref.29.

Important: The Spray gun must be grounded to dissipate any electrostatic charges

which may be created by fluid or air flows. This can be achieved through the Spray

gun mounting, or conductive air/fluid hoses. Electrical bond from the spray gun to

earth should be checked with an ohmmeter. A resistance of less than 106Ohms is

recommended.

Use separate filtered regulated air supplies for

atomizing and cylinder air. Connect the cylinder air

‘CYL AIR’ on top of the body via a control valve.

For fast cylinder operation the control valve should

be fitted as close to the gun as possible or an addi-

tional quick exhaust valve installed in the line.

Attach atomizing air hose to the inlet threaded

hole ‘FAN & ATOM AIR’ under the gun body.

Connect material hose(s) ‘P’ to the spray head. If

material re-circulation is required, remove plugs

(30) & (32). Fit standard connector (¼” BSPP) to

the spray head.

Recommended hose size up to 34 ft. (10 m) long:

Atomization Air = 0.315 in. (8 mm)

Cylinder Air = 0.236 in. (6 mm)

Material = 0.315 in. (8 mm)

AIR AND FLUID HOSES

See pages 11, 12, 13 and 14 for installation details.

Page 8 SB-2-586-E

INSTALLATION (CONTINUED)

START UP (continued)

6. If the finish is too wet, turn the ratchet 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 controlled by turning

adjusting valve FAN ‘F’ (13) clockwise.

8. The spray pattern will give the best results when

perpendicular to the target.

9. The recommended spray distance is 6’’ to 8’’

(150-220 mm).

10. Spray edges first. Overlap each spray 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.

MAINTENANCE

PREVENTIVE MAINTENANCE

1. 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

2. Ensure the nozzle of the fluid tip (2) is clean and

free from damage. Any build up of dried paint

can distort the spray pattern.

REPLACEMENT OF PARTS

TIP (2) & NEEDLE (18)

Remove the air cap (1) by unscrewing its retaining

ring counter- clockwise, remove the index ring if it

remains on the gun head (if fitted and used).

hexagonal spanner.

Unscrew the adjusting needle knob (25) fully in

counter-clockwise rotation, push the needle from

the front of the spay gun, carefully so to avoid

damage the needle end, then pull out the needle

(18) from the back.

If necessary, replace the needle and the tip, first

screw the tip with its air separator ring

(recommended torque between 9.5 to 12 Nm).

Use gun lube to lubricate all the surface of the

needle which will be in contact with the packing

and o ring. Slide the needle into the spray gun from

the back.

Fit the needle springs with its plastic pad (22,23,24)

and replace the needle adjusting knob (25).

PACKING SEAL (9)

Unscrew the air cap (1), tip (2) and its air separator

ring (3).

Unscrew the 4 screws (6) to disassemble the gun

head (8).

Push back the two packing seals (9) using a 5.5 mm

diameter rod from the front of the gun head. Clean

the packing location hole carefully with water or

solvent compatible with material being sprayed.

Fit new packing seals (9) with "U" face towards the

fluid passage.

Turn off air and coating supply and

relieve pressure in the supply lines,

before any maintenance operation.

Turn off air and coating supply and

relieve pressure in the supply lines, or

disconnect from airline and fluid line.

Page 9SB-2-586-E

REPLACEMENT OF PARTS (CONTINUED)

FAN & ATOM AIR VALVE (13)

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 12 mm internal groove for this purpose.

It is recommended to replace the o-ring (14) into the

gun body as soon you disassemble the Piston.

If necessary, when replacing the piston, slightly

lubricate the piston lip with petroleum jelly before

fitting into the gun body.

Before assembling, check the air valve

is in fully open position by unscrewing

it counter-clockwise.
