INSTALLATION

AIR AND FLUID HOSES

See pages 11 and 12 for installation details.

Use separate filtered regulated air supplies for atomizing and cylinder air. Connect all the air and fluid hoses to the manifold (1/8” NPT(f) cylinder air, 1/4” NPT(f) fan and atomizing air.) (See figure 1.)

• Cylinder air ‘C = Cyl’ via a control valve. For fast cylinder operation the control valve should be fitted as close to the gun as possible or an additional quick exhaust valve installed in the line.

• Separated atomizing and fan “F” & “A” air supply.

• If material re-circulation is not required, install 1/4" NPT plug into port ‘R’.

Recommended hose size up to 34 ft. (10 m) long: Atomization Air = 5/16" O.D. (8 mm) Cylinder Air = 1/4" O.D. (6 mm)

FIGURE 1

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 106 Ohms is recommended.

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.

SETTING

Check that the gun has all of the O-rings installed on the sealing surface and check that the locking device (28) is in the correct position to lock the spray gun on to the connecting plate.

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

pressure.

2. The FAN ‘F’ valve controls the spray pattern size.

3. Fluid flow is adjusted with the rear ratchet knob

(25).

For the arrangement of the parts, refer to the exploded view on page 5.

START 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 to set the air pressure at the air regulator to achieve recommended pressures.

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.

SB-2-590-D (11/2016) 7 / 14

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 reduced by turning adjusting valve FAN ‘F’ (13) clockwise.

8. The spray pattern will give the best results when perpendicular to the target.

MAINTENANCE

PREVENTIVE MAINTENANCE

Turn off air and coating supply and relieve pressure in the supply lines, or disconnect from airline and fluid line.

1. Unlock the spray gun from the base plate, remove it, and if available re-attach an alternative gun. Now the spray gun maintenance can be done outside the spray booth while production is still continuing.

9. The recommended spray distance is 6’’ to 8’’ (150-220 mm).

10. Spray edges first. Overlap each 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 use.

Remove the tip (2) and its air separator ring (3) by unscrewing counter- clockwise with 10mm 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 refitting the tip with its air separator ring (recommended torque between 9,5 to 12 Nm).

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 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

Turn off air and coating supply and relieve pressure in the supply lines, before any maintenance operation.

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).

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 packing seal (9) using a 5,5mm diameter rod from the front of the gun head. Clean the packing location hole carefully with adequate solvent.

Fit a new packing seal (9) U face towards the air passage.

SB-2-590-D (11/2016)8 / 14

REPLACEMENT OF PARTS (CONTINUED)

FAN & ATOM AIR VALVE (13)

Before assembling, check the air valve is in fully open position by unscrewing it counter-clockwise.

PISTON (15), O RING (16, 14 & 15C)

Unscrew the rear housing (19) at the back of the gun body counter clockwise, pull out the needle (18).

Use bent nose pliers “T” so to pull out the piston which has a 12mm internal groove for this purpose.

Piston “P+W” and two valve “V” will pull out at the same time. The ring “W” is located by pressing it onto the piston body and can not be removed from it.

The valve “V” can be removed easily from the piston ring by sliding it outward. We recommend to replace the full piston at the same time (Item number SPA-60x-K).

It’s recommended to replace all the O-rings (14, 16 & 15c) in the gun body as soon you disassemble the Piston from the gun.

Slightly lubricate the piston lip before fitting again into the gun body. Use petroleum jelly to lubricate the piston parts and o-rings.
