4. OPERATING INSTRUCTIONS
 WARNING! ENSURE ADEQUATE VENTILATION. DO NOT SpRAy NEAR NAkED FLAMES.
4.1. Mask the area which is NOT to be painted.
4.2. Ensure the object to be painted is free from dust, grease and the surface has been prepared.
4.3. After mixing and thinning the paint, as instructed by the paint manufacturer, fill the paint cup (Fig.1.1) just
over half full.
Note: Mix thoroughly, making sure that the paint is free from lumps. It may be necessary to strain the paint
first.
4.4. Turn the air ON and test your spray on a test panel to get the “feel” of your air brush. Holding the air brush
about 6 inches from the surface press the trigger (Fig.1.2) down and gradually draw back moving the air
brush at a steady rate, parallel to the surface, (Fig.2). For the best result start the motion before
pressing the trigger and a follow through motion after releasing the trigger, (Fig.3).
4.5. Make any necessary spray adjustments. The paint spray pattern can be adjusted by turning the air
adjusting screw (Fig.1.3). The air adjusting screw is fully closed when it has been turned clockwise to the
stop point. The volume of paint dispensed can be adjusted by varying the backward movement of the
trigger (Fig.1.2) and can be pre-set using the micro adjust screw (Fig.1.4).
4.6. Apply paint in accordance with the paint manufacturers guidelines. Continue with this method until the
desired coverage is reached. DO NOT spray too heavily.
Note: when using quick drying paints, it is advisable to clean or immerse the fluid end of the air brush in a
compatible solvent between sprays.

5.1. Empty the paint cup and flush with a suitable solvent.
5.1.1. Fill the paint cup half full of a compatible solvent.
5.1.2. Spray the solvent into a suitable container, this will clean the needle and nozzle assembly. Hold a soft
cloth over the needle cap and spray again, this will force air and the compatible solvent back through the
air brush and clean the internal moving parts.
5.2. Should the air brush become clogged with paint, dismantle the air brush and clean the
component parts as follows: (Note: Numbers in brackets refer to item numbers on the parts diagram).
5.2.1. Turn off the air and disconnect the air hose from the air brush.
 WARNING! The fluid needle has a long sharp point and great care should be exercised when handling it.
5.2.2. Unscrew the adjusting screw (24) and the needle locking nut (19) within the adjusting handle, unscrew
the adjusting handle (21) and carefully slide off the needle.
5.2.3. Remove the needle locking guide (15) and spring (16) and carefully withdraw the fluid needle (20) and
place it somewhere safe to avoid bending it or damaging the sharp point.
5.2.4. Unscrew the needle cap (1) from the nozzle cap (2).
5.2.5. Loosen the nozzle assembly (3) with the spanner provided and unscrew it. If the nozzle needs to be
soaked in solvent remove the O-ring (4) as it may be damaged by the solvent.
5.2.6. Unscrew the air cap body (5) and remove O-ring (6).
5.2.7. The trigger (9) and lever guide (11) will be loose once the needle has been removed, take care to
note the correct position for the lever guide as the air brush will not operate properly if this guide is not
the correct way round.
5.2.8. To remove the needle guide (13), remove screw (39) and undo the stopper (14), the needle guide can
then be removed .
5.2.9. Any components with dried paint on them should be cleaned with a solvent suitable for the paint last
used and may need to be soaked for a while before the paint will come off. Take great care not to bend
the needle when cleaning it and avoid the sharp point.
5.2.10. The air inlet valve (25 to 34) and the fluid adjusting valve (35 to 38) assemblies can be removed and
cleaned without having to dismantle the main air brush, refer to parts diagram for order of assembly
5.3. Reassemble the cleaned air brush in the reverse order.
Check the condition of any O-rings and replace if damaged.
Take care refitting the fluid needle, DO NOT force or overtighten as this may damage the seat or the
needle.
